1 00:00:00,280 --> 00:00:02,960 Speaker 1: Brought to you by the reinvented two thousand twelve Camray. 2 00:00:03,160 --> 00:00:08,920 Speaker 1: It's ready. Are you get in touch with technology with 3 00:00:09,000 --> 00:00:17,560 Speaker 1: tech Stuff from how stuff works dot com. Hello everyone, 4 00:00:17,600 --> 00:00:20,119 Speaker 1: welcome to tech Stuff. My name is Chris Polette, and 5 00:00:20,120 --> 00:00:22,760 Speaker 1: I am an editor at how stuff works dot com. 6 00:00:22,800 --> 00:00:25,919 Speaker 1: And I see sitting across from me as he typically is. 7 00:00:26,960 --> 00:00:29,240 Speaker 1: I think I can't tell. I don't war my glasses on, 8 00:00:29,320 --> 00:00:32,000 Speaker 1: but I think it's senior writer Jonathan Strickland. She'll be 9 00:00:32,120 --> 00:00:35,400 Speaker 1: the same except for bionic eyes. She lost the real 10 00:00:35,400 --> 00:00:40,480 Speaker 1: ones in the robot Wars. Nice. Thank you. Yeah. Today 11 00:00:40,520 --> 00:00:44,440 Speaker 1: we're going to talk about laser eye surgery. We've had 12 00:00:44,479 --> 00:00:46,839 Speaker 1: some people ask us about laser eye surgery and what 13 00:00:46,960 --> 00:00:50,159 Speaker 1: goes into it and exactly how are leasers used in 14 00:00:50,200 --> 00:00:52,559 Speaker 1: the process. But I think that's a record for your 15 00:00:52,680 --> 00:00:56,440 Speaker 1: use of that version of lasers. Yeah, and so we're 16 00:00:56,480 --> 00:00:58,800 Speaker 1: going to, uh, we're gonna kind of break it down 17 00:00:58,880 --> 00:01:02,640 Speaker 1: and talk about it goes into a laser eye surgery procedure. 18 00:01:02,720 --> 00:01:06,360 Speaker 1: And we should also mention I should mention that I 19 00:01:06,400 --> 00:01:08,959 Speaker 1: am very close to someone who has had laser eye surgery, 20 00:01:09,240 --> 00:01:12,000 Speaker 1: not right now, not like physically. I was going to 21 00:01:12,080 --> 00:01:16,000 Speaker 1: say my wife. My wife had laser eye surgery, um, 22 00:01:16,040 --> 00:01:20,360 Speaker 1: and she has been very happily moving around without the 23 00:01:20,760 --> 00:01:24,160 Speaker 1: you need for glasses for several years now. Um. And 24 00:01:24,200 --> 00:01:26,160 Speaker 1: it was very impressive to me because my wife is 25 00:01:26,200 --> 00:01:29,920 Speaker 1: not the sort of person who typically likes people, uh 26 00:01:30,040 --> 00:01:33,800 Speaker 1: you know, mesballs exactly. Yeah. She's that's not high on 27 00:01:33,840 --> 00:01:36,680 Speaker 1: our list of things to do today, but she did 28 00:01:36,680 --> 00:01:39,000 Speaker 1: it anyway. And we're going to kind of talk about 29 00:01:39,040 --> 00:01:42,399 Speaker 1: the process and what you have to do in order 30 00:01:42,440 --> 00:01:45,000 Speaker 1: to get laser eye surgery and what's actually being done 31 00:01:45,080 --> 00:01:48,320 Speaker 1: to you. Yeah, and I think probably the best place 32 00:01:48,360 --> 00:01:52,520 Speaker 1: to start is speaking of eyeballs, with the eyeball itself, yeah, 33 00:01:52,680 --> 00:01:54,560 Speaker 1: and why you might need laser eye surgery in the 34 00:01:54,560 --> 00:01:58,320 Speaker 1: first place, right, Uh. To to to understand this discussion, 35 00:01:58,320 --> 00:02:01,080 Speaker 1: you have to have at least a basic geography of 36 00:02:01,080 --> 00:02:06,080 Speaker 1: the eyeball. So let's talk a little bit about the eye. So, 37 00:02:06,080 --> 00:02:08,680 Speaker 1: so your your eye. The outer coating is this sort 38 00:02:08,720 --> 00:02:12,040 Speaker 1: of tough outer coating called the sclera, and that's sort 39 00:02:12,040 --> 00:02:14,840 Speaker 1: of what keeps the eyeball in its shape. It's it's 40 00:02:14,919 --> 00:02:17,960 Speaker 1: kind of the the well, it's just it's the outer layer. 41 00:02:18,080 --> 00:02:20,639 Speaker 1: And then part of this outer layer about I think 42 00:02:20,680 --> 00:02:24,480 Speaker 1: one sixth of it is the cornea, which is the 43 00:02:24,600 --> 00:02:27,680 Speaker 1: clear outer layer that goes over the part of your 44 00:02:27,680 --> 00:02:30,600 Speaker 1: eye where light actually passes through to get to you know, 45 00:02:30,840 --> 00:02:36,079 Speaker 1: your eyeball. So the cornea is, uh, it's kind of 46 00:02:36,160 --> 00:02:38,040 Speaker 1: like a window in a way, or if you want 47 00:02:38,040 --> 00:02:41,400 Speaker 1: to think of it like a a tablet device or something. 48 00:02:41,440 --> 00:02:45,160 Speaker 1: It's the gorilla glass. It's on the outside that texts 49 00:02:45,200 --> 00:02:49,200 Speaker 1: the the the innards, and then behind the cornea. Well, 50 00:02:49,240 --> 00:02:50,919 Speaker 1: first of all, you've got the sort of a watery, 51 00:02:51,040 --> 00:02:56,639 Speaker 1: clear liquid called the aqueous humor. Yeah, this goes back 52 00:02:56,680 --> 00:03:02,320 Speaker 1: to the old humor's uh idea that dates back centuries 53 00:03:02,400 --> 00:03:06,360 Speaker 1: where we used to think that our bodies we were 54 00:03:07,040 --> 00:03:11,640 Speaker 1: like we're governed by a well, a small group of 55 00:03:11,960 --> 00:03:17,880 Speaker 1: various liquids called humors. We've somewhat developed beyond that at 56 00:03:17,880 --> 00:03:20,520 Speaker 1: this point, although I do think it's it's funny that 57 00:03:20,880 --> 00:03:24,480 Speaker 1: even now we are referring to this particular liquid as 58 00:03:24,480 --> 00:03:27,639 Speaker 1: a humor. Yes, so, so the aqueous humor, it's it's 59 00:03:27,760 --> 00:03:31,079 Speaker 1: this clear, clear liquid that's behind the cornea. It's also 60 00:03:31,200 --> 00:03:33,000 Speaker 1: in front of the iris, and there's a little bit 61 00:03:33,000 --> 00:03:36,160 Speaker 1: behind the iris as well. So then that leads to 62 00:03:36,200 --> 00:03:40,160 Speaker 1: the question, what then is the iris. Well, that's the 63 00:03:40,440 --> 00:03:42,880 Speaker 1: that's the color part of your eye. So for example, 64 00:03:43,480 --> 00:03:47,480 Speaker 1: my iris is blue because it lacks a certain amount 65 00:03:47,480 --> 00:03:50,640 Speaker 1: of pigmentation, which makes it a blue color. My wife's 66 00:03:50,680 --> 00:03:54,560 Speaker 1: eyes are brown. And uh, this is the part of 67 00:03:54,600 --> 00:03:58,120 Speaker 1: the other acts as like an adjustable diaphragm around the pupil. 68 00:03:58,800 --> 00:04:03,600 Speaker 1: So the pupil is that's the dark center of your iris. 69 00:04:03,640 --> 00:04:08,040 Speaker 1: That's the little opening actually that allows light to pass through, right, 70 00:04:08,040 --> 00:04:11,480 Speaker 1: And of course that's the part that the uh enlarges 71 00:04:11,640 --> 00:04:14,000 Speaker 1: or get smaller depending on the amount of light in 72 00:04:14,040 --> 00:04:18,760 Speaker 1: the room. Yeah, it's it's it's really an ingenious kind 73 00:04:18,800 --> 00:04:21,040 Speaker 1: of approach. Really. It's it's the same sort of thing 74 00:04:21,040 --> 00:04:22,960 Speaker 1: that we do with cameras when we have an aperture, 75 00:04:23,600 --> 00:04:25,800 Speaker 1: you know, the aperture of a camera. And you may 76 00:04:25,800 --> 00:04:28,400 Speaker 1: remember this if you listen to our our podcast about 77 00:04:28,400 --> 00:04:31,640 Speaker 1: slow motion. We talked about the aperture quite a bit. Uh. 78 00:04:31,680 --> 00:04:34,800 Speaker 1: That's what allows you to adjust how much light comes 79 00:04:34,800 --> 00:04:38,400 Speaker 1: in through the camera's lens and hits the sensor. Uh, 80 00:04:38,520 --> 00:04:42,600 Speaker 1: same sort of idea here. The iris is what will 81 00:04:42,720 --> 00:04:46,279 Speaker 1: expand or contract around the pupil and thus control the 82 00:04:46,279 --> 00:04:47,920 Speaker 1: amount of light that comes in. So if you walk 83 00:04:47,960 --> 00:04:51,880 Speaker 1: into a dark room, then the it's going to the 84 00:04:51,880 --> 00:04:54,960 Speaker 1: the iris is going to allow more light to pass through. 85 00:04:54,960 --> 00:04:56,640 Speaker 1: It's going to allow more of the pupil to be 86 00:04:56,680 --> 00:04:58,880 Speaker 1: exposed so that you get more light so that you 87 00:04:58,920 --> 00:05:01,480 Speaker 1: can maneuver through because you're gonna be able to you 88 00:05:01,480 --> 00:05:03,440 Speaker 1: need to be able to see if you're in a 89 00:05:03,480 --> 00:05:06,520 Speaker 1: really bright environment. In order to protect the eye, that 90 00:05:06,800 --> 00:05:10,640 Speaker 1: diaphragm is gonna close around the pupil to restrict the 91 00:05:10,640 --> 00:05:13,839 Speaker 1: amount of light that comes in. Right, and of course 92 00:05:14,040 --> 00:05:19,599 Speaker 1: UM there there's more than one UM analog as far 93 00:05:19,640 --> 00:05:22,479 Speaker 1: as the eye and a camera shut. We were talking 94 00:05:22,520 --> 00:05:25,640 Speaker 1: about cameras not too long ago where we we talked 95 00:05:25,640 --> 00:05:28,440 Speaker 1: about the lens and how light passes through the lens 96 00:05:28,520 --> 00:05:32,320 Speaker 1: to the film on the other side, or or an 97 00:05:32,360 --> 00:05:35,080 Speaker 1: image censor in the case of a digital camera. Well, 98 00:05:35,080 --> 00:05:39,720 Speaker 1: in the eye, you've got the retina, which is um 99 00:05:39,760 --> 00:05:42,760 Speaker 1: if you will, on the on the back side of 100 00:05:42,800 --> 00:05:45,400 Speaker 1: the eye, which is what records the image as as 101 00:05:45,440 --> 00:05:48,480 Speaker 1: the light comes through the pupil. Right, You've got you've 102 00:05:48,480 --> 00:05:51,039 Speaker 1: got the pupil, that's the aperture. You also have a lens, 103 00:05:51,200 --> 00:05:53,400 Speaker 1: right behind the pupil. Right, So the lens, the lens 104 00:05:53,480 --> 00:05:56,400 Speaker 1: is what is focusing that light, directing that light so 105 00:05:56,440 --> 00:05:59,800 Speaker 1: that it it hits the focal point ideally, which is 106 00:05:59,839 --> 00:06:04,320 Speaker 1: the retina. And the retina contains certain kinds of cells, 107 00:06:04,440 --> 00:06:10,360 Speaker 1: rod cells and cone cells. These are light censoring light sensors. Essentially, Um, 108 00:06:10,440 --> 00:06:15,280 Speaker 1: he sells sense the presence of light, and uh, through 109 00:06:15,360 --> 00:06:18,960 Speaker 1: a chemical reaction, send that information to your brain and 110 00:06:18,960 --> 00:06:23,559 Speaker 1: then your brain says, hey, I recognize that that's a puppy. Also, 111 00:06:23,640 --> 00:06:27,440 Speaker 1: at interesting point, if you weren't familiar with this, uh, 112 00:06:27,480 --> 00:06:31,080 Speaker 1: the image that you see when you're looking at something 113 00:06:31,240 --> 00:06:34,640 Speaker 1: when it hits your retina, it's actually inverted, just as 114 00:06:34,680 --> 00:06:37,000 Speaker 1: it is in a camera. But yes, that's the So this, 115 00:06:37,000 --> 00:06:39,400 Speaker 1: this is the basic part of the eye. Now, what 116 00:06:39,600 --> 00:06:44,640 Speaker 1: happens when something is just not quite right? For example, Uh, Chris, 117 00:06:44,839 --> 00:06:46,680 Speaker 1: I don't know. Are you near sighted or far sighted? 118 00:06:46,880 --> 00:06:49,960 Speaker 1: I am myopic. I am also myopic. That means we 119 00:06:50,000 --> 00:06:52,440 Speaker 1: are both near sighted, and since we both have our 120 00:06:52,480 --> 00:06:54,720 Speaker 1: our glasses off at the moment, we're both a little blurry. 121 00:06:55,560 --> 00:07:00,960 Speaker 1: So myopia means that the focal point is hitting. Uh, 122 00:07:01,040 --> 00:07:04,160 Speaker 1: it's it's hitting before it gets to your retina. So 123 00:07:04,320 --> 00:07:07,720 Speaker 1: inside your eye there's a you know, the light is 124 00:07:07,800 --> 00:07:11,240 Speaker 1: being directed by the lens to your retina. Uh, those 125 00:07:11,400 --> 00:07:14,560 Speaker 1: the points of light are all converging, right, and that 126 00:07:14,600 --> 00:07:17,400 Speaker 1: point of convergence is the focal point. Now, the focal 127 00:07:17,440 --> 00:07:21,280 Speaker 1: point for those with myopia is in front of the retina. 128 00:07:21,720 --> 00:07:23,760 Speaker 1: It's not hating the retina just right. So that means 129 00:07:23,800 --> 00:07:26,720 Speaker 1: that when we start looking around things, things tend to 130 00:07:26,720 --> 00:07:29,440 Speaker 1: be the further way things are, the blurrier, they tend 131 00:07:29,520 --> 00:07:35,080 Speaker 1: to be. Yes. Um, Now, this can happen through various uh, 132 00:07:35,440 --> 00:07:39,600 Speaker 1: just well, irregularities. There could be irregularities in the cornea 133 00:07:39,760 --> 00:07:42,240 Speaker 1: that can cause this to happen, or in the lens itself, 134 00:07:42,760 --> 00:07:46,160 Speaker 1: or it could be that the eyeball itself is elongated. Yes, 135 00:07:46,400 --> 00:07:49,200 Speaker 1: so that the you know, if the eyeball was not elongated, 136 00:07:49,440 --> 00:07:51,119 Speaker 1: the focal point would be right there on the retina 137 00:07:51,160 --> 00:07:52,840 Speaker 1: where it's supposed to be in Everything will be fine, 138 00:07:52,880 --> 00:07:57,880 Speaker 1: but the eyeball has been stretched. Nice sound effect, thank you, 139 00:07:58,640 --> 00:08:01,560 Speaker 1: doesn't necessarily Jonathan Strict lines, it doesn't necessarily mean that 140 00:08:01,640 --> 00:08:03,960 Speaker 1: someone's actually gone in there and stretch your eyeball. It 141 00:08:03,960 --> 00:08:07,400 Speaker 1: just means that that's kind of the way it developed. Um, 142 00:08:07,440 --> 00:08:10,800 Speaker 1: now far sighting this, which is a hyperopia hyperropia, thank you, 143 00:08:10,840 --> 00:08:14,520 Speaker 1: I'm glad you're ready for that. One's ready? Yeah, hyperopia. 144 00:08:15,040 --> 00:08:19,119 Speaker 1: You've got the focal point that's that's actually behind the retina, 145 00:08:19,240 --> 00:08:22,240 Speaker 1: so when the lights hitting hitting the retina, it's not 146 00:08:22,920 --> 00:08:27,840 Speaker 1: converged on that point like it should be. And uh, hyperopia, 147 00:08:28,120 --> 00:08:33,640 Speaker 1: if you're hyper hyperopic, would that be correct? Hyperopic? Then 148 00:08:33,679 --> 00:08:36,040 Speaker 1: that would mean that you know, you would the the 149 00:08:36,760 --> 00:08:40,040 Speaker 1: closer something is, the more out of focus it is, 150 00:08:40,080 --> 00:08:43,360 Speaker 1: the further away it is, the clearer it is. Also 151 00:08:43,559 --> 00:08:48,840 Speaker 1: in addition to being myopic, I also have an astigmatism, 152 00:08:48,880 --> 00:08:52,040 Speaker 1: I too have an a stigmatism. I think he's just 153 00:08:52,040 --> 00:08:53,920 Speaker 1: just you know, doesn't want me to have one more 154 00:08:53,960 --> 00:08:56,920 Speaker 1: than he does. I only have one. Do you have 155 00:08:56,960 --> 00:09:03,000 Speaker 1: to know? I'm saying, are you and have an a stigmatism? 156 00:09:03,320 --> 00:09:09,160 Speaker 1: Me too? Me too? It just it happen anyway. And 157 00:09:09,160 --> 00:09:12,480 Speaker 1: and an a stigmatism, Um, you have a difference in 158 00:09:12,520 --> 00:09:16,080 Speaker 1: the shape of your cornea or the lens. And basically 159 00:09:16,120 --> 00:09:19,680 Speaker 1: what happens is it creates in effect two focal points 160 00:09:19,679 --> 00:09:24,319 Speaker 1: within your eye. UM. And so basically that sort of 161 00:09:24,360 --> 00:09:27,560 Speaker 1: confuses the way the light is traveling inside your eye, 162 00:09:27,559 --> 00:09:30,200 Speaker 1: and that um, you can have, as we were both 163 00:09:30,240 --> 00:09:32,800 Speaker 1: pointing out just a moment ago, you can have uh 164 00:09:32,840 --> 00:09:36,480 Speaker 1: an a stigmatism on top of another eye condition. Yes, 165 00:09:36,880 --> 00:09:40,400 Speaker 1: it's it's really an uneven curvature of the cornea or 166 00:09:40,600 --> 00:09:44,560 Speaker 1: or lens, and yeah, it's it. It can cause problems. 167 00:09:44,600 --> 00:09:50,080 Speaker 1: So the thing is that the humans are clever. Yeah, 168 00:09:50,160 --> 00:09:53,040 Speaker 1: and we figured out a long time ago that if 169 00:09:53,080 --> 00:09:57,120 Speaker 1: you use a lens of glass and it's curved just 170 00:09:57,280 --> 00:10:00,400 Speaker 1: the right way, the curvature of the glass us can 171 00:10:00,440 --> 00:10:05,360 Speaker 1: direct light so that it corrects for these problems. I 172 00:10:05,400 --> 00:10:08,400 Speaker 1: can't imagine the amount of trial and error it took 173 00:10:08,760 --> 00:10:14,160 Speaker 1: to be able to figure this out. But to correct 174 00:10:14,440 --> 00:10:17,440 Speaker 1: your your vision, you have to, you know, take into 175 00:10:17,480 --> 00:10:22,360 Speaker 1: account what the focal point is doing uh inside your eye. 176 00:10:22,800 --> 00:10:26,240 Speaker 1: So with it's a little bit different between myopia and 177 00:10:26,440 --> 00:10:30,040 Speaker 1: uh and hyperopia. But anyway, the curvature of the lens 178 00:10:30,080 --> 00:10:32,640 Speaker 1: depends upon the condition, right, you know, if it's going 179 00:10:32,679 --> 00:10:34,760 Speaker 1: to be a concave lens for one and a convex 180 00:10:34,880 --> 00:10:37,720 Speaker 1: lens for the other, And honestly, I can't remember the 181 00:10:37,760 --> 00:10:39,240 Speaker 1: one from the other. I guess I could stare at 182 00:10:39,240 --> 00:10:41,080 Speaker 1: my glasses long enough and try and figure it out. 183 00:10:41,120 --> 00:10:45,000 Speaker 1: But um, but the point being that that's what's going 184 00:10:45,040 --> 00:10:47,319 Speaker 1: to direct the light the right way into your eye 185 00:10:47,400 --> 00:10:51,400 Speaker 1: so that it corrects for whatever problem you already have. 186 00:10:52,320 --> 00:10:54,720 Speaker 1: And then, of course, well what if we didn't want 187 00:10:54,720 --> 00:10:58,440 Speaker 1: to wear glasses, what if we wanted something where it 188 00:10:58,520 --> 00:11:02,040 Speaker 1: wasn't you know, this this pair of frames sitting on 189 00:11:02,080 --> 00:11:04,600 Speaker 1: our face. Well that's when we started to come up, well, 190 00:11:04,400 --> 00:11:07,520 Speaker 1: we could maybe make a lens that could sit directly 191 00:11:07,640 --> 00:11:10,720 Speaker 1: on the eye and do the same sort of correction. 192 00:11:11,480 --> 00:11:17,360 Speaker 1: It's going to require a more precise approach because it's 193 00:11:17,360 --> 00:11:20,440 Speaker 1: going to be a much smaller lens that by definition, 194 00:11:20,480 --> 00:11:23,880 Speaker 1: I mean you can't have an enormous lens shoved into 195 00:11:23,920 --> 00:11:28,719 Speaker 1: your eye and expect any sort of comfort. So that's 196 00:11:28,720 --> 00:11:31,720 Speaker 1: where the contact lens idea came from, where we started 197 00:11:31,760 --> 00:11:35,520 Speaker 1: to kind of get you you apply these same kinds 198 00:11:35,520 --> 00:11:39,560 Speaker 1: of thought to a thin lens that could fit directly 199 00:11:39,559 --> 00:11:41,560 Speaker 1: on top of the eye. But then we thought, hey, 200 00:11:41,559 --> 00:11:45,360 Speaker 1: wait a minute, we're really just talking about lenses here. 201 00:11:45,400 --> 00:11:48,200 Speaker 1: Even even the cornea can act somewhat as a lens. 202 00:11:48,240 --> 00:11:52,120 Speaker 1: The cornea on your eye itself directs light. So what 203 00:11:52,280 --> 00:11:55,920 Speaker 1: if we were to reshape the cornia so that it 204 00:11:56,120 --> 00:12:00,160 Speaker 1: corrected for whatever problems we had as you know, as 205 00:12:00,160 --> 00:12:03,120 Speaker 1: far as vision problems are concerned. Uh, what if we 206 00:12:03,200 --> 00:12:06,240 Speaker 1: just did that, then we wouldn't have to wear contact 207 00:12:06,360 --> 00:12:09,160 Speaker 1: lenses or glasses or anything. And that's where the idea 208 00:12:09,280 --> 00:12:15,839 Speaker 1: for corrective surgery comes from. And um, and at its 209 00:12:16,040 --> 00:12:20,720 Speaker 1: very most basic level, what correct what this laser eye 210 00:12:20,760 --> 00:12:24,840 Speaker 1: surgery is doing is it's altering the shape of the 211 00:12:24,960 --> 00:12:28,040 Speaker 1: cornea so that directs light in a way that corrects 212 00:12:28,040 --> 00:12:31,880 Speaker 1: for whatever vision problem you have. That's that's the basic 213 00:12:32,400 --> 00:12:33,960 Speaker 1: you know, when you get down to it, that's what 214 00:12:34,080 --> 00:12:37,360 Speaker 1: laser eye surgery is all about. So it's just it's 215 00:12:37,400 --> 00:12:40,800 Speaker 1: that same principle behind grinding a lens so that you 216 00:12:40,840 --> 00:12:43,560 Speaker 1: can see, you know, in a pair of eyeglasses, but 217 00:12:43,600 --> 00:12:48,640 Speaker 1: now it's applied directly to our biology. It sadly does 218 00:12:48,679 --> 00:12:51,760 Speaker 1: not mean you will actually end up with laser shooting 219 00:12:51,760 --> 00:12:55,599 Speaker 1: out of your eyes, well at least not for most people. No, 220 00:12:56,679 --> 00:13:01,960 Speaker 1: I would think that's a pretty rare side effect. So, yeah, 221 00:13:02,000 --> 00:13:05,120 Speaker 1: where would you like to start with laser eye surgery? Well, 222 00:13:05,160 --> 00:13:07,400 Speaker 1: I was going to talk about sort of the process 223 00:13:07,440 --> 00:13:09,720 Speaker 1: you have to go through before you get laser eye 224 00:13:09,720 --> 00:13:12,640 Speaker 1: surgery done, and then we'll get into what is actually 225 00:13:12,640 --> 00:13:18,440 Speaker 1: going on in a laser eye surgery session. Yeah, because frankly, 226 00:13:18,520 --> 00:13:21,880 Speaker 1: it's it's reminds me of a lot of life events. 227 00:13:22,320 --> 00:13:25,760 Speaker 1: You know. The actual event itself doesn't really take all 228 00:13:25,760 --> 00:13:28,360 Speaker 1: that long. Laser eye surgery only takes a few minutes. 229 00:13:28,640 --> 00:13:32,000 Speaker 1: It can take less than half an hour total um. 230 00:13:32,040 --> 00:13:33,960 Speaker 1: But there is quite a bit of preparation that needs 231 00:13:34,040 --> 00:13:36,880 Speaker 1: that you need to go through beforehand to make sure 232 00:13:36,880 --> 00:13:41,400 Speaker 1: that everything goes smoothly um and preferably not panicky, which 233 00:13:41,440 --> 00:13:44,959 Speaker 1: is the reason that I haven't had it done. Yeah. 234 00:13:44,960 --> 00:13:46,640 Speaker 1: So the first thing you have to do is you 235 00:13:46,679 --> 00:13:49,719 Speaker 1: have to go through and we're talking about a reputable 236 00:13:50,240 --> 00:13:52,480 Speaker 1: laser eye surgeon. This is a good time for us 237 00:13:52,520 --> 00:13:55,240 Speaker 1: to point out there are a lot of different facilities 238 00:13:55,280 --> 00:14:00,280 Speaker 1: out there that offer laser eye surgery services. Do your research. Yes, 239 00:14:00,280 --> 00:14:03,600 Speaker 1: that's a great idea, because I know for a fact 240 00:14:03,720 --> 00:14:06,640 Speaker 1: that there are there's a few in Atlanta that have 241 00:14:06,880 --> 00:14:12,839 Speaker 1: a reputation for being less than honest, Like they'll the 242 00:14:13,080 --> 00:14:17,480 Speaker 1: what the they do is they'll offer this amazing sounding deal. 243 00:14:17,679 --> 00:14:20,280 Speaker 1: And of course we all know the phrase it sounds 244 00:14:20,320 --> 00:14:24,160 Speaker 1: too good to be true. It was probably on the internet. Um, 245 00:14:24,640 --> 00:14:26,720 Speaker 1: and the deal, the deal would be something like two 246 00:14:27,000 --> 00:14:30,960 Speaker 1: d I, which is about a tenth of what some 247 00:14:31,080 --> 00:14:34,920 Speaker 1: eye surgeries cost, you know, and you're thinking, wow, that's amazing, 248 00:14:34,960 --> 00:14:37,280 Speaker 1: and then you know it's got an official sounding name 249 00:14:37,360 --> 00:14:39,200 Speaker 1: and it's gonna be great. And then if you actually 250 00:14:39,200 --> 00:14:41,360 Speaker 1: start doing some research, you'll see that there's often a 251 00:14:41,400 --> 00:14:43,680 Speaker 1: lot of bait and switch involved where you'll go in 252 00:14:43,760 --> 00:14:49,000 Speaker 1: and they'll do this initial I exam and then they'll say, oh, well, 253 00:14:49,040 --> 00:14:53,080 Speaker 1: in your case, because you have this particular you know, 254 00:14:53,200 --> 00:14:57,120 Speaker 1: condition or whatever, it's actually gonna be closer to undred 255 00:14:57,160 --> 00:15:00,240 Speaker 1: per eye or and and just that alone is a 256 00:15:01,000 --> 00:15:02,480 Speaker 1: you know, first of all, that's kind of a shady 257 00:15:02,520 --> 00:15:05,200 Speaker 1: business practice. But beyond that, you don't want, you know, 258 00:15:05,240 --> 00:15:09,400 Speaker 1: you don't know how far their ethics extend into say, 259 00:15:09,640 --> 00:15:13,840 Speaker 1: not being a good doctor. So so in other words, 260 00:15:13,960 --> 00:15:19,040 Speaker 1: do your research. Yeah, quack alert. So, assuming that the 261 00:15:19,040 --> 00:15:22,720 Speaker 1: the facility has got a good reputation, uh, you go in, 262 00:15:22,880 --> 00:15:26,240 Speaker 1: you would get a very thorough eye exam, probably more 263 00:15:26,320 --> 00:15:29,480 Speaker 1: thorough in fact, I would are definitely more through than 264 00:15:29,520 --> 00:15:31,560 Speaker 1: you would get going to just get a pair of 265 00:15:31,600 --> 00:15:34,840 Speaker 1: glasses or contact lenses. I'm sure yes, because they have 266 00:15:34,960 --> 00:15:37,240 Speaker 1: to be they have to be very careful. Um, if 267 00:15:37,240 --> 00:15:41,239 Speaker 1: you're going to go for for lasic, for example, UM, 268 00:15:41,320 --> 00:15:43,960 Speaker 1: your eyes have to fall within a certain set of 269 00:15:43,960 --> 00:15:49,360 Speaker 1: parameters and they can treat myopia, hyperopia, and a stigmatism. 270 00:15:49,400 --> 00:15:52,120 Speaker 1: But it has to be within a certain range. Now, 271 00:15:52,120 --> 00:15:55,920 Speaker 1: of course that's measured in die opters. Um. That's that's 272 00:15:55,960 --> 00:15:58,720 Speaker 1: kind of the degrees of prescription. So you know, if 273 00:15:58,760 --> 00:16:01,640 Speaker 1: you hear someone say, oh, I've got minus three in 274 00:16:01,680 --> 00:16:04,520 Speaker 1: this I and minus two point seven five in that, 275 00:16:04,600 --> 00:16:07,960 Speaker 1: I the myopic. Yeah, their myopic. Yeah that a negative 276 00:16:08,040 --> 00:16:13,280 Speaker 1: number means myopia, a positive number is hyperopia. And then um, 277 00:16:13,400 --> 00:16:16,400 Speaker 1: a stigmatism can go either way. Yeah. Now, we we 278 00:16:16,480 --> 00:16:19,120 Speaker 1: do have a great article on how lasic works on 279 00:16:19,120 --> 00:16:23,680 Speaker 1: the website. Um and according to the research in there, UM, 280 00:16:23,920 --> 00:16:28,200 Speaker 1: myopia treatable with lasic can be from negative zero point 281 00:16:28,240 --> 00:16:30,920 Speaker 1: seven five to negative ten, which is that's a big, 282 00:16:31,680 --> 00:16:34,840 Speaker 1: big range. And and I should also add that depending 283 00:16:34,880 --> 00:16:37,160 Speaker 1: on which doctor you go to, they may tell you 284 00:16:37,200 --> 00:16:40,320 Speaker 1: that if your eyesight falls within you know, a certain range, 285 00:16:40,360 --> 00:16:44,040 Speaker 1: like saying, let's say the negative point seven five to 286 00:16:44,400 --> 00:16:47,000 Speaker 1: say negative one point five. They might say, you know what, 287 00:16:47,160 --> 00:16:50,120 Speaker 1: the the experience you're going to have, the the new 288 00:16:50,280 --> 00:16:52,320 Speaker 1: vision you're going to have, is may not be so 289 00:16:52,440 --> 00:16:56,720 Speaker 1: dramatic as to warrant laser eye surgery. Again, a reputable 290 00:16:57,040 --> 00:17:01,280 Speaker 1: UH clinic is going to tell you if the the 291 00:17:01,320 --> 00:17:03,840 Speaker 1: result is going to be truly noticeable or not. For 292 00:17:03,920 --> 00:17:06,920 Speaker 1: some people, it may not be. I for at least 293 00:17:07,240 --> 00:17:08,919 Speaker 1: years ago, when my wife could have done I was 294 00:17:09,040 --> 00:17:12,199 Speaker 1: right there on the the border like like, you know, 295 00:17:12,240 --> 00:17:14,080 Speaker 1: I could have gotten it done, but it may not 296 00:17:14,160 --> 00:17:16,480 Speaker 1: have been that dramatic. And when you're talking about that 297 00:17:16,520 --> 00:17:19,360 Speaker 1: kind of expense, really do you want to go in 298 00:17:19,440 --> 00:17:22,399 Speaker 1: for that. My wife, however, she had gotten to the 299 00:17:22,400 --> 00:17:24,800 Speaker 1: point of vision where they no longer use the eye chart. 300 00:17:25,080 --> 00:17:27,080 Speaker 1: They would say how many fingers am I holding up? 301 00:17:27,720 --> 00:17:32,440 Speaker 1: So she was an ideal candidate. Well you have to 302 00:17:32,480 --> 00:17:37,560 Speaker 1: hold some up? Um? Yeah, whoa, you need some surgery. 303 00:17:38,040 --> 00:17:41,320 Speaker 1: Hyperopia that they can treat with lacing ranges from plus 304 00:17:41,440 --> 00:17:43,399 Speaker 1: zero point seven five to plus four and then they 305 00:17:43,400 --> 00:17:45,960 Speaker 1: can treat a stigmatism for plus or minus zero point 306 00:17:46,040 --> 00:17:49,360 Speaker 1: seven five to plus or minus four. Um. So that's 307 00:17:49,359 --> 00:17:52,000 Speaker 1: a pretty a pretty decent range of vision that they 308 00:17:52,080 --> 00:17:54,920 Speaker 1: can they can correct. Um. They also look at the 309 00:17:55,200 --> 00:18:00,520 Speaker 1: cornea thickness. It has to be five microns or greater UM. 310 00:18:00,560 --> 00:18:03,000 Speaker 1: That will explain why the cornea has to be at 311 00:18:03,119 --> 00:18:05,239 Speaker 1: least that thick coming up. And that's going to be 312 00:18:05,280 --> 00:18:10,240 Speaker 1: the the squiggly squirmy part where we're both like, okay, 313 00:18:10,280 --> 00:18:14,600 Speaker 1: so here's what happens next. I'll be going out for water, Chris, 314 00:18:14,760 --> 00:18:17,320 Speaker 1: Chris might Chris might go bye bye for about for 315 00:18:17,400 --> 00:18:20,720 Speaker 1: about five minutes that thud. Yeah, But there are other 316 00:18:20,720 --> 00:18:23,920 Speaker 1: types of laser eye surgery that you can pursue if 317 00:18:24,000 --> 00:18:26,760 Speaker 1: your cornea is not of that thickness, if it's if 318 00:18:26,800 --> 00:18:29,200 Speaker 1: it's thinner than that, there are other types of laser 319 00:18:29,200 --> 00:18:34,040 Speaker 1: eye surgery you can look into, so to speak. Um. 320 00:18:34,119 --> 00:18:38,240 Speaker 1: And then your pupil uh should be no more than 321 00:18:38,320 --> 00:18:42,800 Speaker 1: six point five millimeters in diameter UM, although you know 322 00:18:42,880 --> 00:18:46,160 Speaker 1: there are advances now that allow you to work with 323 00:18:46,280 --> 00:18:49,320 Speaker 1: up to eight point five UM. Also, so if you've 324 00:18:49,400 --> 00:18:52,960 Speaker 1: been Diesel from that that movie where he's got those 325 00:18:53,119 --> 00:18:57,040 Speaker 1: huge corneas, the huge pupils, that just wouldn't work. Lady 326 00:18:57,080 --> 00:18:59,720 Speaker 1: Gaga from that that one video, Yeah there you go. Yeah, 327 00:18:59,760 --> 00:19:04,280 Speaker 1: those those folks, I'm sorry, or practically any Disney character, 328 00:19:05,040 --> 00:19:07,879 Speaker 1: because I mean, have you seen Tangled. That girl's eyes 329 00:19:07,920 --> 00:19:12,440 Speaker 1: are huge. Yeah, Sailor Moon's not gonna have it done either. Um. 330 00:19:12,480 --> 00:19:15,920 Speaker 1: So yeah. And also if you're pregnant, have heart problems, 331 00:19:15,920 --> 00:19:20,160 Speaker 1: severe heart problems anyway, Um, if you're taking drugs such 332 00:19:20,160 --> 00:19:26,280 Speaker 1: as medicine for migraines or acne, um, you have a 333 00:19:26,320 --> 00:19:30,439 Speaker 1: condition called kara to conas. I'm hoping I'm pronouncing it right. 334 00:19:30,480 --> 00:19:32,439 Speaker 1: I didn't check the pronunciation, but that's a thinning of 335 00:19:32,480 --> 00:19:36,480 Speaker 1: the cornea condition. And um, actually I might be Uh, 336 00:19:36,520 --> 00:19:40,879 Speaker 1: I might not be eligible either because certain conditions like 337 00:19:40,920 --> 00:19:45,040 Speaker 1: autoimmune diseases, one of which I have, UM, vascular disease, 338 00:19:45,240 --> 00:19:48,240 Speaker 1: different kinds of eye diseases, and diabetes. All these things 339 00:19:48,400 --> 00:19:52,640 Speaker 1: might prevent you from going through with a lasic procedure. Um. 340 00:19:52,720 --> 00:19:54,359 Speaker 1: So these are things that the doctor is going to 341 00:19:54,400 --> 00:19:57,080 Speaker 1: have to talk to you about. Um, and I would 342 00:19:57,160 --> 00:20:00,840 Speaker 1: encourage history. Yeah. You need to be honest too, because 343 00:20:00,960 --> 00:20:03,800 Speaker 1: you know, even though you may not want to wear glasses, uh, 344 00:20:03,920 --> 00:20:06,280 Speaker 1: you know, this is serious business and you could end 345 00:20:06,359 --> 00:20:08,520 Speaker 1: up with results that you are not happy with. It 346 00:20:08,600 --> 00:20:11,760 Speaker 1: can be complications as well, I mean even yes, you know, 347 00:20:11,880 --> 00:20:14,800 Speaker 1: it could be that everything goes well, but uh, you 348 00:20:14,960 --> 00:20:18,280 Speaker 1: have some complications during the healing process, and if your 349 00:20:18,320 --> 00:20:21,560 Speaker 1: medical history means that you can't have certain kinds of 350 00:20:21,640 --> 00:20:25,360 Speaker 1: drugs to to help that healing process along, that could 351 00:20:25,440 --> 00:20:27,600 Speaker 1: be an even bigger problem down the road. So yeah, 352 00:20:27,640 --> 00:20:30,600 Speaker 1: it's very important. And then the actual exam, you're going 353 00:20:30,640 --> 00:20:33,120 Speaker 1: to be looking through lots of different devices that are 354 00:20:33,119 --> 00:20:37,160 Speaker 1: going to be measuring how your eyes are receiving light. 355 00:20:37,440 --> 00:20:40,720 Speaker 1: And there's actually technically mapping out your eyes the inside 356 00:20:40,760 --> 00:20:44,960 Speaker 1: of your eyes. Um. There's a thing called a corneal topographer. Yes, 357 00:20:45,080 --> 00:20:47,159 Speaker 1: that's where they type on your eyes, right, that's a 358 00:20:47,160 --> 00:20:53,600 Speaker 1: typograph back topographer. It actually maps the cornea, so it's 359 00:20:53,640 --> 00:20:59,040 Speaker 1: it's looking at the actual shape and thickness of the cornea. Um, 360 00:20:59,119 --> 00:21:02,199 Speaker 1: and it's too uh to really determine exactly how the 361 00:21:02,280 --> 00:21:06,240 Speaker 1: light is behaving once it hits that part of your eye. Um. 362 00:21:06,280 --> 00:21:11,040 Speaker 1: There's also the pupilometer, which is another device that's looking 363 00:21:11,080 --> 00:21:13,119 Speaker 1: specifically at your pupil I mean there's not a big 364 00:21:13,160 --> 00:21:17,200 Speaker 1: surprise there, right, you have a student in your eyeball. Yeah, 365 00:21:17,320 --> 00:21:22,240 Speaker 1: and then the their software very powerful software, but working 366 00:21:22,240 --> 00:21:25,040 Speaker 1: behind the scenes, that's mapping out your eye so that 367 00:21:25,680 --> 00:21:29,840 Speaker 1: the surgeon is going to know exactly what sort of 368 00:21:29,840 --> 00:21:32,520 Speaker 1: of adjustments they're going to need to make to your 369 00:21:32,560 --> 00:21:37,320 Speaker 1: cornea in order for it to um to direct light 370 00:21:37,400 --> 00:21:39,159 Speaker 1: the way you need it to be so that you 371 00:21:39,160 --> 00:21:42,120 Speaker 1: don't have to wear glasses or contact lenses anymore. So 372 00:21:42,160 --> 00:21:45,840 Speaker 1: it's it's pretty complex stuff. I mean, it's um pretty 373 00:21:45,840 --> 00:21:49,200 Speaker 1: fascinating to see. And also a laser eye surgery procedure 374 00:21:49,280 --> 00:21:55,320 Speaker 1: often requires two people, a surgeon and a patient, well 375 00:21:55,440 --> 00:21:59,920 Speaker 1: beyond the patient to people to actually to do the procedure. 376 00:22:00,320 --> 00:22:03,560 Speaker 1: The surgeon and then there's usually a an operator who's 377 00:22:03,600 --> 00:22:07,960 Speaker 1: working on one of the laser machines. And so now 378 00:22:08,000 --> 00:22:11,280 Speaker 1: we've now we've talked about the process where let's say 379 00:22:11,280 --> 00:22:14,240 Speaker 1: that you've gone through you've had your eye exam, you've 380 00:22:14,280 --> 00:22:17,480 Speaker 1: done your medical history, and they've determined your what is 381 00:22:17,480 --> 00:22:20,200 Speaker 1: called an ideal candidate. Now that does not mean you 382 00:22:20,240 --> 00:22:23,000 Speaker 1: are the perfect person to have had laser eye surgery. 383 00:22:23,080 --> 00:22:26,280 Speaker 1: It just means that you fit those parameters that uh, 384 00:22:26,520 --> 00:22:28,960 Speaker 1: you don't have anything outlying any of those parameters that 385 00:22:29,000 --> 00:22:32,080 Speaker 1: would that would cause concern. It appears that it will 386 00:22:32,119 --> 00:22:35,960 Speaker 1: work out. Yes, Uh, now is the time where you 387 00:22:36,000 --> 00:22:39,639 Speaker 1: start to um to to actually go through the surgery itself. 388 00:22:39,720 --> 00:22:42,239 Speaker 1: And I think I think we can walk through the 389 00:22:42,320 --> 00:22:47,080 Speaker 1: laser process because that's still fairly common. I mean that's 390 00:22:47,119 --> 00:22:49,280 Speaker 1: that's actually probably one of the most common forms of 391 00:22:49,359 --> 00:22:52,240 Speaker 1: laser eye surgery out there. But we'll also talk about 392 00:22:52,280 --> 00:22:56,200 Speaker 1: how the other kinds are a little different. So, um So, first, 393 00:22:56,200 --> 00:22:58,720 Speaker 1: when you arrive to get your laser eye surgery done, 394 00:22:58,880 --> 00:23:02,240 Speaker 1: one thing that's happens fairly frequently is that they offer 395 00:23:02,320 --> 00:23:05,800 Speaker 1: you something to calm your nerves. Yes, because it turns 396 00:23:05,800 --> 00:23:08,240 Speaker 1: out when a lot of people, when they're thinking they're 397 00:23:08,240 --> 00:23:10,080 Speaker 1: going to be laying down on the table with someone 398 00:23:10,119 --> 00:23:13,480 Speaker 1: shooting laser beams into their eyes, they get a little anxious. 399 00:23:13,920 --> 00:23:16,240 Speaker 1: I can't imagine why. Actually, that's not the part that 400 00:23:16,280 --> 00:23:19,280 Speaker 1: makes me anxious, but we'll get into that. Um So, 401 00:23:19,359 --> 00:23:21,920 Speaker 1: you know it's the part immediately before the laser gets 402 00:23:21,920 --> 00:23:23,880 Speaker 1: shut into your eye. That would be the part. Yeah, 403 00:23:23,880 --> 00:23:26,240 Speaker 1: that's the part where it gets I'll score me so 404 00:23:26,480 --> 00:23:28,159 Speaker 1: and yeah, I mean basically they're going to set up 405 00:23:28,160 --> 00:23:31,440 Speaker 1: an appointment when you do your prep work. I don't 406 00:23:31,480 --> 00:23:33,920 Speaker 1: think that they actually would take you back immediately and 407 00:23:33,960 --> 00:23:35,800 Speaker 1: go all right, you look good, let's go. No, No, 408 00:23:35,960 --> 00:23:39,479 Speaker 1: it's usually it's usually a day or two between. Speaking 409 00:23:39,520 --> 00:23:42,399 Speaker 1: from my wife's experience, she went in and had the 410 00:23:43,040 --> 00:23:46,840 Speaker 1: um the work that there up work done, and then 411 00:23:47,000 --> 00:23:48,560 Speaker 1: it was a couple of days later after they had 412 00:23:48,600 --> 00:23:50,639 Speaker 1: had a chance to really look at the data and 413 00:23:51,000 --> 00:23:53,159 Speaker 1: they arranged for the time. And you also have to 414 00:23:53,280 --> 00:23:56,160 Speaker 1: go there with someone else to drive you home. Yes, 415 00:23:56,280 --> 00:23:58,200 Speaker 1: because you will not be able to use your eyeballs. 416 00:23:58,359 --> 00:24:00,920 Speaker 1: Yeah for that. Yeah, because actually you're going to have 417 00:24:01,040 --> 00:24:05,040 Speaker 1: some limited eyeball use ately afterwards. You can't put your 418 00:24:05,040 --> 00:24:08,480 Speaker 1: weight on them. Yeah, exactly. Um, use some eye crutches, 419 00:24:09,119 --> 00:24:13,480 Speaker 1: So I crunches. Um are those apple products? Um? No, 420 00:24:13,600 --> 00:24:18,080 Speaker 1: it's not the lower case I E. I see. Um. 421 00:24:18,400 --> 00:24:21,280 Speaker 1: So the next thing they're gonna do, once you're you're 422 00:24:21,840 --> 00:24:23,879 Speaker 1: sure you want to go through this, of course, they 423 00:24:23,920 --> 00:24:25,840 Speaker 1: also make you sign a waiver saying that you understand 424 00:24:25,880 --> 00:24:28,440 Speaker 1: that there are things going on where they're gonna shoot 425 00:24:28,480 --> 00:24:32,240 Speaker 1: lasers in your eyeballs and uh, there are risks involved 426 00:24:32,280 --> 00:24:34,720 Speaker 1: with that, and part of this depends a lot on 427 00:24:34,800 --> 00:24:39,360 Speaker 1: your cooperation, like still and and not running from the office. Screaming. 428 00:24:40,080 --> 00:24:43,399 Speaker 1: Um again, I'm just imagining what would happen with me. 429 00:24:43,760 --> 00:24:48,399 Speaker 1: They assuming your your nerves of steel are holding, are holding, 430 00:24:48,720 --> 00:24:51,480 Speaker 1: they will go ahead and put some topical anesthetic in 431 00:24:51,560 --> 00:24:54,040 Speaker 1: your eyes. Yes, so this is to numb your eyes 432 00:24:54,720 --> 00:24:58,159 Speaker 1: because they will need to touch them and uh. And 433 00:24:58,320 --> 00:25:00,840 Speaker 1: once you're once that started to take effect, you're lead 434 00:25:00,880 --> 00:25:04,280 Speaker 1: into the operating room where you lay down on a table. 435 00:25:04,280 --> 00:25:08,280 Speaker 1: It's usually a padded table and they position you so 436 00:25:08,520 --> 00:25:11,920 Speaker 1: that you're going to be under the machine that goes 437 00:25:12,000 --> 00:25:16,960 Speaker 1: ping and uh and and then they have to well, 438 00:25:17,000 --> 00:25:19,320 Speaker 1: they have to secure your eyelids so that you're not 439 00:25:19,359 --> 00:25:21,680 Speaker 1: going to be blinking. Yes, because you cannot blink, so 440 00:25:21,840 --> 00:25:25,200 Speaker 1: they may be using usually a combination of things. There's 441 00:25:25,240 --> 00:25:28,720 Speaker 1: usually some sort of tape that's safe to put on 442 00:25:28,920 --> 00:25:31,960 Speaker 1: your your eyelids to keep your eyes open. There's also 443 00:25:32,000 --> 00:25:35,439 Speaker 1: a device that will sit on top of the bottom 444 00:25:35,480 --> 00:25:37,560 Speaker 1: part and top part of your eyelids to keep those 445 00:25:38,080 --> 00:25:41,680 Speaker 1: them stationary. Um. This looks a lot like the device 446 00:25:41,760 --> 00:25:46,000 Speaker 1: that was used in a famous documentary called a clockwork orange. Um. Yeah, 447 00:25:46,040 --> 00:25:48,200 Speaker 1: it's a little freaky. If you're looking at someone who's 448 00:25:48,240 --> 00:25:51,520 Speaker 1: getting this done. The eyelids speculum. Yeah. Yeah, it's to 449 00:25:51,760 --> 00:25:53,960 Speaker 1: hold those eyelids in place, because of course, if you 450 00:25:54,000 --> 00:25:56,280 Speaker 1: blink what the laser is going, it's gonna totally mess 451 00:25:56,359 --> 00:25:58,840 Speaker 1: up the procedure. So they have to they have to 452 00:25:59,280 --> 00:26:04,959 Speaker 1: stabilize and keep your eyelids from moving. Um and uh. 453 00:26:05,359 --> 00:26:09,920 Speaker 1: They also put down a ring around your eye that 454 00:26:10,920 --> 00:26:13,119 Speaker 1: that stops you from being able to move your eye around. 455 00:26:13,400 --> 00:26:17,720 Speaker 1: You're you're looking directly up or directly straight straight ahead 456 00:26:18,320 --> 00:26:19,760 Speaker 1: is the best way of putting it. Not up as 457 00:26:19,840 --> 00:26:22,919 Speaker 1: in your eyes are turned up, but looking straightforward. It's 458 00:26:22,920 --> 00:26:24,840 Speaker 1: just because you're laying on your back, it just happens 459 00:26:24,840 --> 00:26:29,400 Speaker 1: to be up. And then as they the next step 460 00:26:29,480 --> 00:26:33,240 Speaker 1: is the squigly part. Are you ready, Chris, Okay, So 461 00:26:34,720 --> 00:26:39,320 Speaker 1: they pull out the microcra tome Yes, see they have to. 462 00:26:39,840 --> 00:26:44,480 Speaker 1: They're gonna put some marks on your cornea to identify 463 00:26:44,600 --> 00:26:48,359 Speaker 1: where it is, whether they're where they're going to use 464 00:26:48,480 --> 00:26:53,800 Speaker 1: the microcarra tome um. Basically, when you're dealing with something 465 00:26:53,840 --> 00:26:57,200 Speaker 1: as sensitive as vision, and you know, the professionals want 466 00:26:57,240 --> 00:26:58,760 Speaker 1: to do a good job, they're going to want to 467 00:26:58,800 --> 00:27:00,800 Speaker 1: be as accurate as possible, so they're going to mark 468 00:27:00,840 --> 00:27:06,080 Speaker 1: your cornea to make sure that they use the microcarratone right, 469 00:27:06,119 --> 00:27:08,879 Speaker 1: I don't even want to talk about it, Micart. What 470 00:27:09,000 --> 00:27:11,840 Speaker 1: it was. It's a surgical instrument. Okay, It's a blade, 471 00:27:12,400 --> 00:27:17,440 Speaker 1: a very thin blade, and this blade is used to 472 00:27:17,680 --> 00:27:21,640 Speaker 1: cut a flap in your cornia, which is then pulled 473 00:27:21,880 --> 00:27:26,920 Speaker 1: back so that the laser can shape the corn This 474 00:27:27,119 --> 00:27:30,040 Speaker 1: is this is this is entertaining and painful to watch. 475 00:27:30,160 --> 00:27:33,040 Speaker 1: This is the part that grosses me out. I'm sorry. Okay, 476 00:27:33,119 --> 00:27:37,119 Speaker 1: So yeah, so there's actually this and this is lazing. 477 00:27:37,280 --> 00:27:39,399 Speaker 1: There are other versions of laser ey surgery that do 478 00:27:39,560 --> 00:27:41,360 Speaker 1: not use this, and some of them don't even use 479 00:27:41,520 --> 00:27:45,960 Speaker 1: a microcarratone blade. They have a special laser that will 480 00:27:46,000 --> 00:27:49,080 Speaker 1: cut this flap. But in lazing eye surgery, there is 481 00:27:49,160 --> 00:27:51,520 Speaker 1: a flap that's cut and pulled back so that the 482 00:27:51,600 --> 00:27:54,160 Speaker 1: laser can start to shape the cornea without that outer 483 00:27:54,359 --> 00:27:59,840 Speaker 1: layer in place. And and so at this point, the 484 00:28:00,560 --> 00:28:03,760 Speaker 1: the laser, which is um called an uh well it 485 00:28:03,840 --> 00:28:06,520 Speaker 1: is an ex semer or x simer E x C 486 00:28:06,760 --> 00:28:09,120 Speaker 1: I M E R. Actually did not look up the pronunciation. 487 00:28:10,119 --> 00:28:12,240 Speaker 1: But this is the laser that does the actual shaping. 488 00:28:12,720 --> 00:28:17,119 Speaker 1: It starts to vaporize parts of the cornea. And what's 489 00:28:17,160 --> 00:28:22,360 Speaker 1: doing is it's shooting ultraviolet UH blasts and the lasers 490 00:28:22,400 --> 00:28:24,320 Speaker 1: in the ultra violet lank range, which means you can't 491 00:28:24,320 --> 00:28:27,720 Speaker 1: see it, right, it's outside the range of human sight UM. 492 00:28:27,960 --> 00:28:32,040 Speaker 1: And what it's doing is is exciting uh the molecules 493 00:28:32,200 --> 00:28:34,520 Speaker 1: in the cornea to the point where the molecular bonds 494 00:28:34,600 --> 00:28:37,359 Speaker 1: break down. So it's actually that's what I talk about 495 00:28:37,359 --> 00:28:40,920 Speaker 1: when vaporizing. It's not heating the eyeball up. Actually, a 496 00:28:41,000 --> 00:28:43,640 Speaker 1: cool laser I expect you to break down. And when 497 00:28:43,640 --> 00:28:45,720 Speaker 1: I mean cool laser, I don't mean that it's like 498 00:28:45,880 --> 00:28:48,880 Speaker 1: super awesome, although it is. I mean it doesn't heat 499 00:28:49,240 --> 00:28:51,960 Speaker 1: up the tissue. Now, remember earlier I mentioned that your 500 00:28:52,120 --> 00:28:55,040 Speaker 1: cornea has to be five microns are greater when they 501 00:28:55,040 --> 00:28:59,160 Speaker 1: start this procedure, and that's because when they're done using 502 00:28:59,200 --> 00:29:05,560 Speaker 1: this laser, there has to be between two microns of 503 00:29:05,760 --> 00:29:09,160 Speaker 1: thickness once they're done. Yeah, so there has to be 504 00:29:09,280 --> 00:29:11,800 Speaker 1: enough for them to leave the proper amount once they're finished, 505 00:29:11,840 --> 00:29:14,640 Speaker 1: otherwise you can't do this. So now, now using this 506 00:29:14,840 --> 00:29:19,280 Speaker 1: laser to vaporize these molecular bonds and to reshape your cornea. 507 00:29:19,480 --> 00:29:23,760 Speaker 1: That's essentially the same thing on on a grand concept 508 00:29:23,880 --> 00:29:29,000 Speaker 1: level as grinding a glasses lens. So that's gonna been light. 509 00:29:29,040 --> 00:29:30,680 Speaker 1: The way way it's the same thing is just we're 510 00:29:30,760 --> 00:29:32,960 Speaker 1: using lasers and your actual eye to do it, which 511 00:29:33,000 --> 00:29:37,760 Speaker 1: is pretty phenomenally awesome. It's also kind of scary. Um 512 00:29:37,880 --> 00:29:40,320 Speaker 1: not at the end of it. After it might take 513 00:29:40,640 --> 00:29:44,400 Speaker 1: I don't know, seventeen to twenty seconds to do this, Chris, 514 00:29:44,520 --> 00:29:47,840 Speaker 1: because be okay, okay, yeah, per ie. Um. They then 515 00:29:48,200 --> 00:29:52,120 Speaker 1: replace the flap back down on your eye and it heals. 516 00:29:52,600 --> 00:29:55,320 Speaker 1: I mean, it sets down in place and is is 517 00:29:56,080 --> 00:29:59,320 Speaker 1: healing as soon as it touches back down. That is 518 00:29:59,360 --> 00:30:01,959 Speaker 1: one of the very cool things I think about that. Um. 519 00:30:02,080 --> 00:30:05,840 Speaker 1: They the doctor will also probably put a little antibiotic 520 00:30:05,920 --> 00:30:07,840 Speaker 1: on the flap just to make sure that there are 521 00:30:07,880 --> 00:30:11,720 Speaker 1: no bacteria getting in there. Yeah, but but it maybe 522 00:30:11,720 --> 00:30:14,800 Speaker 1: it starts to to heal, which is pretty phenomenal. Um. 523 00:30:15,520 --> 00:30:19,320 Speaker 1: The the whole process only takes, like I said, about 524 00:30:19,360 --> 00:30:22,720 Speaker 1: twenty seconds per eye. Uh and uh. Usually when you're 525 00:30:23,000 --> 00:30:25,360 Speaker 1: down there, you'll hear people talk about how the doctor 526 00:30:25,400 --> 00:30:28,040 Speaker 1: told him to look at, say like a blinking red light. 527 00:30:28,800 --> 00:30:31,440 Speaker 1: That red light is not the laser. That's just a 528 00:30:31,560 --> 00:30:35,120 Speaker 1: light that let's focus folk. Yeah, you're supposed to focus 529 00:30:35,240 --> 00:30:37,760 Speaker 1: on that while this ultra violet laser is blast in 530 00:30:37,840 --> 00:30:41,600 Speaker 1: your your cornea way. Um. And then once the flap 531 00:30:41,680 --> 00:30:44,280 Speaker 1: comes down, you're usually you're given several different kinds of 532 00:30:44,360 --> 00:30:49,120 Speaker 1: eye drops before you leave. Uh. There's a moisturizing eye drop, 533 00:30:49,200 --> 00:30:52,400 Speaker 1: because after you get this process done, your eyes are 534 00:30:52,440 --> 00:30:55,720 Speaker 1: gonna have a little bit of difficulty uh, generating the 535 00:30:55,880 --> 00:30:58,000 Speaker 1: right kind of moisture to keep your eyes comfortable, so 536 00:30:58,080 --> 00:30:59,920 Speaker 1: you're gonna have to actually endit. Eye drops in on 537 00:31:00,000 --> 00:31:03,200 Speaker 1: a pretty regular basis. In fact, the first couple of days, 538 00:31:03,320 --> 00:31:05,880 Speaker 1: it's it's like every hour you've got to add eye drops, 539 00:31:06,280 --> 00:31:09,120 Speaker 1: and then as the time goes on, you have to 540 00:31:09,520 --> 00:31:11,959 Speaker 1: use them less and less frequently. And my wife at 541 00:31:12,000 --> 00:31:15,560 Speaker 1: this point rarely ever uses eye drops, but for the 542 00:31:15,640 --> 00:31:18,720 Speaker 1: first year she was using them on on a fairly 543 00:31:18,760 --> 00:31:21,880 Speaker 1: regular basis, although that that schedule changed over time, like 544 00:31:21,960 --> 00:31:23,960 Speaker 1: after the first three months, it didn't need to be 545 00:31:24,080 --> 00:31:27,000 Speaker 1: as frequent, um, and now it's it's rare when she 546 00:31:27,080 --> 00:31:30,520 Speaker 1: needs them, but occasionally she does. Uh. And then you 547 00:31:30,640 --> 00:31:32,840 Speaker 1: might also have antibotic eye drops that you might have 548 00:31:32,920 --> 00:31:35,600 Speaker 1: to add every now and then. And some places apparently 549 00:31:35,680 --> 00:31:37,920 Speaker 1: put give you a kind of gel that you put 550 00:31:38,000 --> 00:31:40,280 Speaker 1: on the inside of your lower eyelids so that when 551 00:31:40,320 --> 00:31:43,560 Speaker 1: you're asleep, it keeps your eye moisturized while you're sleeping. 552 00:31:43,600 --> 00:31:46,560 Speaker 1: My wife, I don't remember her getting that, UM. I 553 00:31:46,600 --> 00:31:48,920 Speaker 1: should have asked her before I left the house this morning, 554 00:31:49,000 --> 00:31:52,040 Speaker 1: but I do not recall her getting that kind of stuff. 555 00:31:52,040 --> 00:31:53,920 Speaker 1: I do remember the other kinds of eye drops though. 556 00:31:55,080 --> 00:31:58,480 Speaker 1: And then they of course schedule, as you know, a 557 00:31:58,520 --> 00:32:03,200 Speaker 1: lot of surgical procedures. UM. They also schedule regular appointments, 558 00:32:03,320 --> 00:32:06,240 Speaker 1: even even as as soon as the next day, to 559 00:32:06,400 --> 00:32:12,520 Speaker 1: make sure okay UM. And then gradually as time goes on, uh, 560 00:32:13,040 --> 00:32:15,160 Speaker 1: you know, they check less frequently. You know, there'll be 561 00:32:15,240 --> 00:32:17,880 Speaker 1: a year check up, but you know it's one day, 562 00:32:18,000 --> 00:32:20,680 Speaker 1: and then they'll check the next week, the next month, UM, 563 00:32:21,080 --> 00:32:24,680 Speaker 1: an increasing increasingly longer periods, just to make sure everything 564 00:32:24,760 --> 00:32:26,239 Speaker 1: is healing the way it's supposed to, Just to make 565 00:32:26,240 --> 00:32:29,280 Speaker 1: sure that there are um, that your eyes are doing 566 00:32:29,360 --> 00:32:31,680 Speaker 1: what they're supposed to do when you're not suffering any 567 00:32:31,960 --> 00:32:34,400 Speaker 1: ill effects from the surgery. Because in the case of 568 00:32:34,800 --> 00:32:38,280 Speaker 1: I mean, there there are times when the flap can 569 00:32:38,320 --> 00:32:40,640 Speaker 1: get a wrinkle in it. Yeah, I was wondering if 570 00:32:40,680 --> 00:32:42,760 Speaker 1: we're going to get into that. Yeah, that can happens 571 00:32:42,840 --> 00:32:44,480 Speaker 1: like that. That can cause a little bit of blurry 572 00:32:44,600 --> 00:32:48,840 Speaker 1: vision and may require a second surgical procedure in order 573 00:32:48,880 --> 00:32:53,880 Speaker 1: to get it straightened out, so so speak. Um. Also, 574 00:32:54,040 --> 00:32:56,960 Speaker 1: you know there's a possibility that they may remove too 575 00:32:57,040 --> 00:33:03,440 Speaker 1: little or too much of the corn. Yeah. Uh, yeah, 576 00:33:03,520 --> 00:33:05,240 Speaker 1: they have to be That's why they have that's why 577 00:33:05,280 --> 00:33:08,320 Speaker 1: they're doing that whole long pre ops sections so that 578 00:33:08,440 --> 00:33:12,280 Speaker 1: they can determine that as precisely as possible to to 579 00:33:12,400 --> 00:33:15,440 Speaker 1: reduce that risk as much as they can. And of course, 580 00:33:15,480 --> 00:33:17,960 Speaker 1: again this also depends a lot on the patient. You 581 00:33:18,120 --> 00:33:19,880 Speaker 1: have to be able to lay there and be still 582 00:33:20,000 --> 00:33:22,440 Speaker 1: while your eye is being held open and lasers are 583 00:33:22,480 --> 00:33:24,480 Speaker 1: being shot into it after someone's cut a flap in it. 584 00:33:25,560 --> 00:33:27,200 Speaker 1: It's a little it's a bit of a challenge for 585 00:33:27,280 --> 00:33:30,080 Speaker 1: some of us. Um. Let's talk really quickly about some 586 00:33:30,160 --> 00:33:32,560 Speaker 1: of the other kinds of laser eye surgery besides lazing. 587 00:33:33,920 --> 00:33:36,960 Speaker 1: The one of the the precursors to lazing, and it's 588 00:33:36,960 --> 00:33:39,120 Speaker 1: still in use in a lot of places, is PRK 589 00:33:39,640 --> 00:33:44,720 Speaker 1: laser ice surgery. Or photo refractive care TEC to me, Wow, 590 00:33:44,920 --> 00:33:46,240 Speaker 1: I didn't know I was gonna be able to say that. 591 00:33:46,560 --> 00:33:50,480 Speaker 1: In this one, they actually scrape away the outermost layer 592 00:33:50,520 --> 00:33:54,200 Speaker 1: of the cornea with the laser and then reshape the 593 00:33:54,280 --> 00:33:59,360 Speaker 1: tissue on the underlying surface of the cornea UM and 594 00:33:59,440 --> 00:34:01,360 Speaker 1: then they have and then you have to allow the 595 00:34:02,200 --> 00:34:05,560 Speaker 1: the protective layer that was scraped off to grow back, 596 00:34:05,720 --> 00:34:08,520 Speaker 1: So there's actually a longer healing period with PRK than 597 00:34:08,560 --> 00:34:12,239 Speaker 1: with lazing. They can use that process to h to 598 00:34:12,400 --> 00:34:15,600 Speaker 1: work on near sidedness and a stigmatism at the same time, however, 599 00:34:15,680 --> 00:34:19,759 Speaker 1: which is nice. Yep. And uh, then there's lazac with 600 00:34:19,920 --> 00:34:22,839 Speaker 1: an e. The lasic we're talking about is with an eye, 601 00:34:23,920 --> 00:34:27,480 Speaker 1: but LAZAC is a slightly more advanced version of PRK 602 00:34:27,640 --> 00:34:31,520 Speaker 1: that uses um alcohol and solution to soften and then 603 00:34:31,640 --> 00:34:35,640 Speaker 1: remove the epithelium, which is that protective layer, the almost 604 00:34:35,719 --> 00:34:41,560 Speaker 1: layer of the cornea. Yeah, LASAC is laser epithelial curatatamliusis Yeah, 605 00:34:42,120 --> 00:34:44,239 Speaker 1: I think I didn't mangle that terribly yep. And then 606 00:34:44,280 --> 00:34:47,960 Speaker 1: there's epilasac, the modified version of that that uses a 607 00:34:48,040 --> 00:34:53,120 Speaker 1: separator so that the because then in the traditional lazec 608 00:34:53,160 --> 00:34:57,640 Speaker 1: you're actually removing the epithelium entirely, and epilasic you're creating 609 00:34:57,680 --> 00:35:01,000 Speaker 1: a separator so that you preserve that epithelium and then 610 00:35:01,080 --> 00:35:03,279 Speaker 1: replace it on the ice. So it's like you take 611 00:35:03,320 --> 00:35:05,640 Speaker 1: the cover off, fiddle around a bit, and put the 612 00:35:05,680 --> 00:35:09,239 Speaker 1: cover back on. It's probably a better eye surgeons out 613 00:35:09,280 --> 00:35:12,400 Speaker 1: there just love me for saying that. Um. There's l 614 00:35:12,440 --> 00:35:18,399 Speaker 1: t K or laser thermo keratoplasty. Uh. Now that it's 615 00:35:18,480 --> 00:35:22,120 Speaker 1: used mainly for far sightedness and a stigmatism, and in 616 00:35:22,239 --> 00:35:24,640 Speaker 1: this case they actually are using heat. They're using the 617 00:35:24,760 --> 00:35:28,040 Speaker 1: heat of a laser beam to shrink and reshape the 618 00:35:28,160 --> 00:35:31,480 Speaker 1: cornea rather than removing it, so they're actually reshaping it. 619 00:35:31,560 --> 00:35:35,480 Speaker 1: They're pushing the stuff around as opposed to cutting it away. Um. 620 00:35:35,719 --> 00:35:38,799 Speaker 1: And it's supposedly a much faster healing process than most 621 00:35:38,880 --> 00:35:42,640 Speaker 1: other kinds of corrective surgery, and it's generally considered to 622 00:35:42,680 --> 00:35:49,960 Speaker 1: be less invasive. So it's uh, that's an interesting approach. 623 00:35:50,040 --> 00:35:55,240 Speaker 1: There's also there's a custom view lazic, conventional intra lazic, 624 00:35:55,440 --> 00:35:59,320 Speaker 1: custom view intra lazic. These are all variations on the 625 00:35:59,440 --> 00:36:04,279 Speaker 1: basic lasic approach. Basic LAZIC, and there are of course 626 00:36:04,360 --> 00:36:07,600 Speaker 1: complications with some of these. We mentioned some before. I've 627 00:36:07,680 --> 00:36:11,160 Speaker 1: I've known people to undergo LASIC and complain of some 628 00:36:11,239 --> 00:36:14,440 Speaker 1: problems with night vision where they see halos. There's a 629 00:36:14,480 --> 00:36:18,960 Speaker 1: lot of that where everyone looks like master chief no. Um. 630 00:36:19,160 --> 00:36:21,200 Speaker 1: Basically when you look at a light source, it looks 631 00:36:21,239 --> 00:36:25,120 Speaker 1: like it has shimmering circle around it. Yeah. Yeah, especially 632 00:36:25,200 --> 00:36:27,080 Speaker 1: things for like if you're driving at night and you'll 633 00:36:27,120 --> 00:36:30,600 Speaker 1: know no halos around headlights, things like that. Or you're 634 00:36:30,640 --> 00:36:33,920 Speaker 1: sensitive to bright light. Yeah, yeah, you're light sensitivity. Especially 635 00:36:34,000 --> 00:36:36,560 Speaker 1: for the first few days, it's probably gonna be a little, uh, 636 00:36:36,880 --> 00:36:39,200 Speaker 1: a little rough. But for some people it just it 637 00:36:39,320 --> 00:36:41,880 Speaker 1: stays that way. So like my wife, she wears sunglasses 638 00:36:41,880 --> 00:36:44,799 Speaker 1: a lot more frequently than she used to. And uh 639 00:36:45,200 --> 00:36:50,120 Speaker 1: for for some people too, I've heard that in some cases, uh, 640 00:36:50,239 --> 00:36:54,000 Speaker 1: it is possible for your eyes basically to slowly regress 641 00:36:54,080 --> 00:36:58,400 Speaker 1: to where they were before. Um. I don't know exactly 642 00:36:58,440 --> 00:37:00,280 Speaker 1: why that is. You know, I have read report works 643 00:37:00,440 --> 00:37:04,040 Speaker 1: that that it happens. Um. But and you know, some 644 00:37:04,160 --> 00:37:07,360 Speaker 1: people who have and you know, enjoyed the benefits of 645 00:37:07,400 --> 00:37:09,680 Speaker 1: the surgery for years. And then there are others who 646 00:37:10,400 --> 00:37:13,560 Speaker 1: gradually returned to uh to the way they were before. 647 00:37:13,880 --> 00:37:16,360 Speaker 1: I'm sure that it probably since since part of the 648 00:37:16,400 --> 00:37:19,120 Speaker 1: cornea has been removed, I would imagine that it's probably 649 00:37:19,160 --> 00:37:22,680 Speaker 1: not as uh drastic change so it was. But I've 650 00:37:22,719 --> 00:37:25,400 Speaker 1: I've read that that that can happen. I would imagine 651 00:37:25,440 --> 00:37:27,400 Speaker 1: if you have some sort of condition that continues to 652 00:37:27,719 --> 00:37:30,239 Speaker 1: change the shape of your eyeball, that would be it 653 00:37:30,280 --> 00:37:32,359 Speaker 1: would be a big problem because the focal point would 654 00:37:32,360 --> 00:37:35,759 Speaker 1: constantly be changing then or gradually be changing. Yes, well, 655 00:37:35,800 --> 00:37:38,320 Speaker 1: I think that wraps up this discussion about laser eye surgery, 656 00:37:38,440 --> 00:37:42,520 Speaker 1: which I was it was interesting.
