It works (fixed my eyes and got me a jet slot), but it does hurt, and it takes a long time to heal. Look up Recurrent corneal errosion (i think that is what it is called). Basically, your eyes dry at night and the healing cells stick to your eyelid. if you open your eyes really fast in the morning after this happens, you basically tear the surface layer off, risk damaging your eyes, set back the healing time, and wake up everyone in your dorm with your banshee like screams.
For the first few months, use drops constantly. I would keep them with you at all times and use them regularly for atleast a year. Buy a humidifier for your room when you sleep.
Keep going in for checkups, but tell them if something hurts, especially when they're removing the protective contacts they put in after the surgery.
If you're going to do it, don't skimp. Get the best doctor/equipment you can find.
P.S. Don't watch video of the surgery or you'll never go through with it. As for the guy who had to go back. . . I had nightmares I'd have to go back for round 2.
