I went through it a year ago, then again 6 months ago.
The surgery itself is painless and it’s hard to screw up as long as you have a competent doctor and you follow his/her insturctions. The worse thing during the surgery is being nervous. THat and the fact you can’t just close your eyes and pretend it’s not happening(well, one eye is covered, the other is held open with a special device).
The worst part is the evening of the surgery. You will not be allowed to drive yourself (so have a SO or friend drive you there and back). Once you finish, your eye(or eyes, if you got both done) are dry, icthy and irrated. You are NOT allowed to rub them for several days and are asked to wear googles while you sleep to make sure you don’t do it while you are asleep. Where I went, I got a medical kit, with pain pills, sleeping pills, and various kids of eyedrops to help the pain. You don’t have to use any of them, but there are there if you need them.
Basically, the night it happens, going to bed early is a good idea(since your vision goes in and out for the evening(which makes it really hard to watch TV or Read, and the aforementioned pain). My eyes felt normal the next day in both cases.
Usaually you’ll be asked to come back for appointments at regular intervals for checkups(at least I did). Unless something goes horribly wrong, you won’t need glasses anymore, or less dreadful, you won’t need ones nearly as thick.
However, there are several risks invovled. There’s a low chance(less then 10%, can’t remember the exact number) that the surgery will make your vision worse and any good clinc/doctor will inform you of these risks and make sure you understand them before you pay. I was asked to watch a 10 minute video detailing all the risks and was asked if I understood and to sign a waiver to that effect. They should also test your eyes and vision to make sure you aren’t at risk for this these kinds of problems.
Another problem, though less dangerous, is that people with large pupils have a greater chance of having issues with lights in the Dark (Haloing, which can affect your night driving). I have medium-largish pupils and did have some issues with this, but nothing that created problems in my life. Most people it goes away after 6 months. Some people it will stick around forever(those with large pupils are prone to this).
Again, this depends on your Doctor/Clinic, but if you don’t get your eyes fixed all the way to 20/20 (and some people will never be able to get all the way there, 20/25 being the best it can be corrected too), you will probably be able to get an enhancement to take it the rest of the way. Some places will likely charge for the 2nd surgery, while others (like the one I went to, basically said everything for a year was covered by the intial payment. Making the 2nd surgery essentially free )
But I’m sorry…I disgress. I wasn’t sure how much you wanted to know. I apologize if I bored you.
My case was this. Went in Last Spring with medium-largish pupils and Coke-bottle glasses, but was still a good candidate. Told because of vision problmes since I was a kid, I’d never be 20/20, but rather a best of 20/25.
Signed the papers, payed them, and went through it. The next day, no glasses and saw a lot better then I could without glasses before. However, as time passed, I noticed that I still couldn’t see as well as could before with glasses. Late last year, after many checkups, I was told I had only been corrected about halfway between where I started out and best case enhancement.
I did it again. Now I’m about 20/20 or so and the haloing at night is not noticable(Or I’ve gotten so used to it that I don’t notice). I’ve been released from regular checkups(now just annual). No glasses other then sunglasses (I’m still a bit light sensitive because of my pupil size and that will probably never go away. However, I don’t mind because sunglasses are a hell of a lot cooler then regular ones).
Lastly (Hold in there, I’m almost done), I can’t back this up from personal experince, from what I’ve been told, apparently it does get slightly trickier around the age of 40 due to natural eyesight decay. However, that’s probably been dicussed with you.
gets off the soapbox
Sorry for the long digression. I hope this helps you.
