I had it done the day before Thanksgiving this year. Unfortunately mine didn't get corrected perfectly and I'll probably have to have it redone. I opted for the lifetime insurance on it though, which trust me is a good thing. I'm about 20/30 in both eyes now with trouble reading things clearly from more than a few feet away. The nighttime halo effect is annoying as hell too. I also definately recommend not watching anyone else have the procedure done right before you, I watched the person in front of me and when it was my turn I started panicking a little. I'm 26 btw and had it done at Lasikplus in Alpharetta, Ga.
I'd definately still do it again, but the fact that I don't see as good as I did while wearing glasses is quite aggrivating. Also the constant need for eye drops is a bit of a pain.
As far as the flap healing, it doesn't heal, because they can never cut it again, if you have to have it redone they wiggle it loose apparantly. And I don't know what my 20/whatever rating was before the surgery, but my prescription was about -7.0 in both eyes.
