I had it done in 2001. I went in -270/-290 and came out 20/20 and 20/15. It was a bit pricey at the time I did it but if you discount buying glasses every 3-5 years, contact lenses and all that baggage plus the priceless experiences of never needing glasses or contacts again it was well worth it. It also helped my pool game which helped in those occasional tournaments and side action matches, so it was maybe even a cash flow positive experience for me
With the results I had I would recommend the procedure to anyone.
Some minor negs on the experience:
a) for the first 6 months or so night time lights had more halo around them. As time wore on the halo was less evident. Now I cant even say i notice it at all.
b) My night vision is a bit weaker than it was with glasses at night. It almost seems to me that my eyes receive less light because it seems to me that things get a bit darker closer in than I thought I was getting with glasses. I could be wrong on this, as I thinks its very very minor.
c) When they did my eyes, they used a machine that held your eye stable. They numbed my eyes and used these things that made me think of Clockwork Orange at the time to keep my eyelids open and then the machine decended down (i was laying flat on my back in this machinery). The machine that pressed down in my case pressed a hair too hard and burst some surface capillaries on my eye. Gave me a minor bloodshot eye, plus the experience of having this thing pressing down on your eye wasnt so cool. Definitely endurable but not something id want to do much more of. Maybe technology has advanced, and in your case and they dont do it this way still.
