Well, you presumably read how bad my eyes were. My corneas are going to take a while to re-thicken, if they ever do. My doc said I could expect my vision to remain more-or-less as is 'til i hit late middle age. If/when it starts to deteriorate, I may have to correct it somewhat with contacts or glasses. But so long as it is within normal realms of short-sightedness, I'll be perfectly happy with the treatment. As I said, without contacts/glasses, I was completely helpless. Couldn't shave myself.
That said, LASIK approval ratings from patients are well above 90%, with most of the complaints coming from people with unrealistic expectations. Let's not shy away from every medical advance of the 20th/21st centuries because not enough time has passed for us to see every last long-term ramification. There haven't been enough studies on ANYTHING.
