Hi,
I just found this article:

I had PRK laser surgery in 2000 with no negative effects. At that time, I vaguely remember something about the US Navy allowing their pilots to get laser surgery. Also, (and I'm certainly no medical authority) I remember being tested with some sort of drops that fully dilate your pupil. I was told that the corrected area, when you have surgery, is approximately 8mm. If your pupil dilates more than 8mm, you will see coronas around lights at night. If it doesn't, you won't. Apparently, some less reputeably shops will not do this test as it will discourage some of their customers....oops, I mean patients. The hazing is a little harder to predict, but from what I remember PRK has (or had at that time - things change) a lower chance of this sort of complication. PRK hurts like hell though.
Anyways, I'm dragging this all from my imperfect memory
Cheers
