I had PRK done a month or so ago. For pilots or other active people, I'd strongly recommend getting the PRK procedure done over LASIK, since there is no cut in your eye. Read about the differences. You really want to do your research with this procedure.
My vision is now 20/20 and 20/15, up from 20/400. I got the procedure done because I want to join a division of the military that requires nearly perfect uncorrected vision. The procedure itself was painless, however the recovery was awful. The pain was intense, and you don't know the outcome of the procedure until about a week later. According to the doctor, my recovery was very rapid compared to the average population, which is what I would expect, since I'm in pretty excellent shape. LASIK apparently has a much easier recovery although you have a cut in your eyeball for the rest of your life. The Navy has decided that this is not acceptable, and I did too.
For most people I'm not sure if I would recommend the procedure. If contacts work for you, why wouldn't you stick with them? That being said, I really love waking up and being able to see, not having to deal with glasses and contacts, having better than perfect vision, and the fact that I'm now eligible for a whole lot more things than I was before. If you don't have that last bit, or care, it may not be worth the risk of complications. Nothing is guaranteed, and in the end they are your eyes. The one other thing I will add, is GO TO THE BEST DOCTOR around. Ask other eye doctors and surgeons who they send their problems to, and go to that doctor. If you can't afford the best, don't get the procedure done at all. Your vision is not the place for 2 for 1 eyeball deals, or shady mall store doctors.
