I had Lasik about 15 years ago and it worked, but I had side effects with night vision that still bother me.
Bright objects (like traffic lights) against a dark background caused ghosting, basically double vision that only occurs in certain circumstances. I used to love to look at the night sky and that doesn't really work anymore, it's hard to play outfield under the lights, etc.
I told the doctor who performed the surgery about it and he swore that he had never heard of it before and that I didn't have double vision because it didn't happen all the time...I could type "ghosting" into google at the time and have hundreds of hits. Basically, my doctor was a massive jerk who lied and denied.
I will admit that I didn't help my own healing process by going for a long bike ride with ski goggles on...doctor OKed the ride with goggles, but he probably didn't mean vented goggles like I used. I was experiencing ghosting before that and I suspect it wouldn't have gone away even without the ride.
This was back in the day of using a blade to make the initial cut, I think that is done with a laser these days and probably heals a lot cleaner.
I was probably a poor candidate for the surgery as I was almost turned away at my initial eval because they couldn't get a good scan due to my large irises and pupils...they finally got something they thought was good after many tries, but I probably should have just left at that point.
It's great to not have to wear glasses, but the ghosting is a PITA to this day. Can't really do anything short of another surgery to try to fix it...
