Let us know how it's gone Ranger,have long been interested in having mine done but am too chicken.Have just gone for some contact lenses as a compromise.
Didn't know about the 'no exercise' period,how long is it?
No exercise for 7 days afterwards, I imagine they do not want to risk you jumping around too much and shaking your cornea loose, I would imagine getting similar advice after any surgery ('cause that is what it is)
As for people being worried about it, the best I can explain it was as uncomfortable (not painful) at the very beginning when they fold back the front of your eye as they use a vacuum, I think, to lift it away and so there is a bit of pressure. The actual laser bit is fine with my entire procedure lasted less than 10 minutes, I was in the place less than 1 hour beginning to end.
As for after effects (I am now on day 3) vision was perfect 3ish hours after, the only 'pain' was similar to wearing my contacts too long and the only worry in the morning when I wake up and think "S*** I've fallen asleep in my lenses, oh that's right I can see now" and I now have better than 20/20 vision. All in all very impressed
