I had this done about 20 years ago. Your eye will be dry for a while, maybe a few months, use wetting drops. Your eye has probably dried out in the wind. Cutting the flap cuts the nerves that send signals to the brain to make tears. But it does usually get better.
I was a -12.00 diopter , I saw 20/20 for two years then had to get glasses again. Couldn't have it done again, said since my eyes were so bad I didn't have enough cornea left to take any more off.
I'm still glad I had it done. I can see about 20/40 (without glasses) during daylight although my low light vision isn't as good. My eye doctor told me they do a better job today than they did then on the low light thing, they treat a larger area of the cornea.
If you have progressive myopia(nearsightedness), meaning your eyes get worse every year, they will still get worse. The surgery doesn't do anything to fix what is causing it, just cuts a permanent contact lens out of the cornea of the eye.
My next eye surgery will be for cataracts, LOL, so not too concerned about my Lasik.
I know a lot of people that have had Lasik and they all love it.
The good places around here are about $4,000 for both eyes. My wife and I had ours done at Duke University. Some may be as low as $2,500 but I would stay with the most experienced doctors. Some of these doctors have done more than 10,000 of these procedures.
