I had lasik done many years ago, and I couldn't be more pleased.
I remember the night of the surgery, lying awake (because they make you take a nap right after the surgery so your eyes heal a bit). I was wearing these goggles (so you don't rub your eyes for the first day or so). I looked across the room and noticed the alarm clock read 3:00 AM. I put my head back on the pillow, stared at the ceiling, and felt frustrated that I couldn't sleep.
Then it hit me. I COULD READ THE ALARM CLOCK ACROSS THE ROOM! I woke up my wife and was bouncing off the walls. I ran to the window and started looking at the stars -- first time I'd seen them clearly in decades. Everything was so clear and crisp. It was absolutely AMAZING!
The next day, we discovered that I now have better than 20/20 vision. Whoohoooo! And things have remained crisp and sharp for many years.
True, when I hit about agd 45, I started needing reading glasses. But that's true of everyone whether or not they have lasik, because it's a different part of the eye involved. If I had remained near-sighted, my vision would have balanced out the need for reading glasses for another few years, but I'd need 'em eventually.
Would I do it all over again? YOU BET! In fact, I would have done it at an earlier age -- as soon as the doctors say my eyes had pretty much settled in their development. (Early 30s? I can't remember what they told me.)
I still get a kick out of buying regular old cheapie sunglasses off the rack.
