I had lasek done last sept (so about 14 months ago). The only thing I did was wish I got it done sooner. It has really improved my pool game, in the past year, I went from an average apaSL4 to a SL6 (8ball). I have not had a lot of issues with night halo's and glare, if you currently have astigmatism you probably already experience them anyways. I would suggest paying extra and getting the procedure where they use the laser to cut the flap open instead of the microblade. The procedure with the laser is actually called lasek instead of lasik,.... google lasek vs lasix and you can read all about it. Its more expensive, but you get better results and reduced night halos and etc.
The surgery itself is fairly painless, its more uncomfortable than anything, the suction that they use to keep your eye still slightly burns buts its over fairly quickly. The vision disturbances during the procedure are kinda neat when its not blacked out when they are putting the flap back in place.
Having said that the hours 1 through 4 after the surgery where absolute hell for me. They tell you to sleep through that, but I couldn't fall asleep, my eyes just keep watering and watering. I wanted to rub them in the worst way but I couldn't. (they give you goggles that you have to wear when you are sleeping for a week or two). I finally fell asleep after about hour 4 and woke up an hour or two later and was 95% improved. zero discomfort after day one (except those PITA goggles you have to wear at night).
My vision was 20/20 when I left after the surgery and at my follow up appointment a week later my vision improved to 20/10.
The only thing I would do different would be to insist I be given something stronger than tylenol/ ibuprofen right after the surgery to help sleep and alleviate discomfort. I have read that some eye doctors automatically prescribe it, and some don't think you need it. I would ask about that in your Preop and find one who will give you something to help.
Oh yeah, one more thing, don't use the drops with presevative in them, them will make your eyes itch. Get the drops that come in single dose vials. The brand I found best is called refresh plus, Costco and Sam's have a fairly good deal on them. Switching to those drops really made a big difference.
