Laser Vision Surgery for Developers?

cyclops asks: "I have been contemplating about going for LASIK surgery for a couple of years. I want to get rid of my dependency on glasses or lenses because I really find them cumbersome. The main thing that is stopping me now is that like you, programming is my livelihood and thus I spent a major part of my day staring into the monitor. I have readthat there is always a certain percentage of patients not regaining 20/20 vision but it's OK for them since most of them don't need that sharp vision during work. I am about to consult with a LASIK surgeon but I would love to hear anecdotal evidence about your experiences, to hear if it works out for you eventually. (I have stable myopia of -5.50 and astimagtism of -1.00 for 3 years already)." Ask Slashdot has handled this issue in the past in two previous articles: this one from 1999, and a related article from 2000. With at least 2 years since the last time this question was posed, how has medical technology improved in this aspect? For those unwilling or unable to take advantage of Laser Surgery, have other viable alternatives arisen in the past two years?

Then there's the risk

[hatless]

Me, I wear glasses, ones with a pretty thick lens on the left at that. The frames get a little in the way of my peripheral vision. But I don't want Lasik. Why? Because of the failure rate--even if it's somehow down to only 1%, and I'm not sure it is.

Forget worrying about not achieving the 20/20 vision you want and that many people get from it. Worry instead about the real risk of corneal damage that will leave your vision worse than it was before, with permanent starbursts and haloes like you're looking through scratched, scuffed glasses all the time.

Will this happen to you? Probably not. In fact, if you have the sort of vision that Lasik corrects, you have a well over 95% chance of getting the great vision without glasses that you want. It's just that if you draw the short straw, you could find your ability to read a screen pretty thoroughly ruined, with or without glasses.

Weigh the benefits against the risks, and if you decide to do it, note that most surgeons have you sign a boilerplate contract that bars you from suing them if your vision is ruined. Who's the real winner?

Wrong

I had LASIK 2 years ago and have no night vision problems. For the first couple months, there was a slight 'ghosting' effect around bright lights at night. That has completely disappeared. My night vision before the surgery was excellent and it continues to be so.

I'd be careful about wildly comparing everythings "danger factors" with driving at rush hour. Especially eye surgery. It is morbid, but chances are high that in a car accident you either won't really have to handle the results or get over it rather quickly. In eye surgery however, you're quite unlikely to die if the surgeon hits the "disintegrate" button, but you'll probably be blind as a mole for the rest of your life. Now, I would think that most of us are at an age where it would be very difficult at least to adopt to a completely changed lifestyle, especially if your defect was rather minor beforehand (nothing really requiring glass bricks).

I don't want to say that eye surgery is a bad thing. It has its merit in repairing defects that are otherwise incorrectible. But if it's (ab)used as purely cosmetic surgery, then I think the dangers outweigh the use.

Also note that my sight is rather good (-1.0 on both eyes, with a nasty embryonal core in the left which makes me see double on this eye), and so I might be unqualified to say this. But what I know is that every kind of surgery has very real dangers and that it should be regarded as a last resort.

Better than contacts but sometimes "normal" is bad

[GlenRaphael]

Personally, I think that if there is any chance at all that a cosmetic surgery will prevent me from doing serious computer work, then the cosmetic surgery is not worth it.

If you wear contact lenses, there is a small chance you may permanently screw up your eyesight due to a scratched and/or infected cornea. The risks of serious negative outcome associated with LASIK are smaller than the normal risks associated with contact lenses, so people who wear contacts now are probably on net helping their odds of keeping decent eyesight if they get LASIK.

Me? I got LASIK a few years ago. Best $4400 I ever spent. The main caveat I might add is that for a computer geek sometime it sucks to have "normal" vision. Back when I was nearsighted it was possible for me to read ultra-fine print. I could print program listings 8 or 16 pages to one side of a laser-printed page and still read it. I could squint a bit and easily make out individual pixels on my Newton or CRT monitor - often useful when doing graphic work.

Now, my vision is just normal. Meaning I no longer need glasses to read stuff 20 feet away, but the flip side is I can't take them off to read stuff 2 inches away. Sometimes I miss that ability.

Re:Don't - just don't

A friend of mine is a senior uni researcher in optometry. She's told me that the flap of cornea that they open up in order to do the surgery never heals properly and that even mild trauma is able to re-open the cut. This can result in infection, scarring and permanent damage. She wears glasses and preaches openly against this technology.

Hmm... conflict of interest? Optometrists are largely in danger of becoming an obsolete species thanks to vision correction surgery. I detect some possible bias here. Mild trauma is NOT going to open up the cut, any more than mild trauma is likely to rebreak a formerly broken bone, any more than mild trauma is likely to open a cut that healed on your skin years ago. LASIK is fairly prevalent now, and I've NEVER heard of a single case of the corneal flap avulsing, let alone see one (and I see lots of bad car accidents every day, none of which complain of vision loss without other severe trauma to the eye, i.e. denucleations, hyphemas, etc.).

Basically, I'd take your friend with a grain of salt. Get more than one side of the story, preferable one whose livelihood isn't endangered by the new technology.

A: This is not OT.
B:I chose to comment at this level because you're talking about my prescription, or close to it - 10.0 and 10.5 nearsighted, with a couple of diopters of astigmatism.... at least, it was. It was a scary decision, but i figured the chances of permanent crippling vision damage was miniscule, and the chance of some degradation was still pretty small. I figured i could wear even worse coke-bottle-bottoms, switch to a larger font, and maybe squint a bit, maybe even use a screen reader, for my job. On a mountainside, glasses can be a real hassle. Fogging in the cold, sliding down your nose in the heat, and, the possibility of them falling off and leaving me hoping for a high-altitude rescue (contacts are even worse when you're that far out on your own) made me take the chance.
I had to go with PRK, as my cornea is only about as thick as the flap they cut for LASIK. During my post-procedure phase, I accidentally took the cortisone drops a few days too long, and ended up making myself slightly farsighted. I'm only 39, so i've still got good focal range, and can focus down to about 8 inches, but I'm going to need reading glasses sooner than I should have. I still don't regret it. I'm a solid 20:15, and can jump out of bed in the middle of the night seeing perfectly.
Note that if you're much past 10, nobody will do you, so it can't get rid of 2-inch-thick lenses. What it comes down to is your own priorities, what losses you can live with, what risks you can stomach. If you're a couch potato, barfly, gamer, or otherwise sedentary, vision correcting surgery is probably a waste of time, stress, money, and karma. For me, not a day passes where I don't think about it and giggle about the fact that I'm no longer a cripple when I sleep.
