I had PRK in November and like most people, the procedure was quick and painless, but the next few days were a bit uncomfortable and it takes some time for your eyes to heal so get lots of rest, and use your drops and medication as recommended and you will be fine. Definitely worth it though since my vision is perfect at this point. I'm at the Naval Academy and I have had classmates who have had both Lasik and PRK so I think the military may be accepting Lasik for aviators. But I would double check that.
