I have. The biggest thing to know is people have different results and reactions, so it is hard to compare. My aunt, myself, and one of my coworkers all went to the same doctor.
My aunt - Afterwards she said her eyes burned, but she was able to sleep it off, wake up and see a couple hours later. She had to use eye drops after and still uses them I believe. I think she has said she see halos from time to time? I don't.
My coworker - she didn't feel any burning and was fine. She also had to use quite a bit of eye drops, not sure if she still does.
Myself - Quite different. My eyes burned afterwards and I was trying to go to sleep (they tell you to do so after surgery, sleep off the burn and when you wake up you can see). Well I fortunately/unfortunately do not have dry eyes. Afterwards, my eyes were tearing up so badly because of the burning, it would not stop, so falling asleep was impossible and I felt the burn for awhile. Luckily I have rarely had to use any eye drops, only used the required medical ones they required (quite expensive for a teeny tiny bottle).
The bad for me, was that I have a great immune system and my eyes overhealed as they called it. They actually healed too quickly from the surgery and my eye sight regressed in one of my eyes (I can't remember which one). This was not immediate, this was a couple months later. It really never hurt my overall vision though because my other eye stepped up and allowed me to see clearly, it was just when trying to use the one eye on the tests that I did not do so well. Once my eye site stopped changing in the one eye, they did PRK.
I am now 20/20 and have been since the surgery. I would still do it again going through all of this. I said it before I had it, if I could have 1 year without glasses and contacts, I would do it in a heartbeat.
