I got LASIK in Thailand (TRSC) in 2006; went from 20/80 and 20/60 to 20/10.
It did increase dryness for a year or two (but, I was also in a desert), and caused "halos" around lights at night, but that went away after a year or two.
Probably the best $2500 (for two eyes; wavefront!) I ever spent. I had a huge ($60/night) hotel suite at the Royal Meridien for a week, and took the hotel limo to/from the center, since I didn't want to deal with navigating Bangkok or taxis while blind. I could read by the next day, by setting my laptop to 80x24 full-screen mode, but mostly just drank, ate, and slept in my room for a couple days.
