My wife and I had our eyes corrected at the same time. I opted for PRK, she went for LASIK. She was driving within 2 days, complaining about a little pain -- but really, essentially pain free. I was basically lying / sitting in a dark room, with a few T3s for about a week.
Both of us were at 20/20 on our first examinations. My eyes felt relatively normal by two weeks, at which point I was back at the gym, no problem. I think it was a week before i could work or drive again after the surgery. For the first six months or so there was a little haloing when driving at night, the eyes felt dry, and I was told to wear sunglasses every time I was outside. Which I sometimes did. For me, it would have been difficult to spend 8 hours a day at a computer for the first couple of weeks.
Now, my eyes don't feel any different from before the surgery (+2 years), although I notice occasionally if I'm really dehydrated that the vision gets a little blurred.
A decision like this is about evaluating risk. The risk of complications from either PRK or LASIK is really low. You can probably find a bunch of decent articles about this on pubmed. Lots and lots of procedures have been performed. If people were going blind in large numbers then (i) it would be all over the news, (ii) less people would have the surgery, and (iii) it would probably become illegal to perform. However, there are real risks, as some of the links have shown. You've just got to decide at what point does a risk become worthwhile, for something that's essentially a vanity surgery, is it 1 in 100, 1 in 1,000, 1 in 10,000, etc. ? How does it compare to the risks of everyday activities, like driving a motor vehicle, or crossing the road? Are you willing to accept the risk for the perceived benefit of the surgery.
I'm pretty happy with the decision I made to have PRK. I'm also sure there's many grapplers out there that have had LASIK, and have not and will not have any problems.
