Well,
I think this topic has been covered before. But here goes my .02 worth.
I had the operation performed in Canada. Numerous reasons, but primarily because the doctor had numerous years of experience and was the designer for the first Lasik equipment. Not that he uses that equipment anymore, but you get the idea.
I was completely 20/20 within hours of the operation. I was 20/100 and 20/80 in left/right eyes respectively. I also had an astigmatism in both eyes. No evidence of that within hours as well.
I did alot of research before undertaking this project. I called the Canadian BBB about this clinic, I contacted former patients with eyesight issues similar to mine. Most importantly, you've got to have the FAA forms filled out to the letter of the pre/post op testing on your eyes. You have to be cleared by your FAA Medical Doc before flying again as well.
Cost was $2000 US. That included pre/post op exams with a local optometrist. The clinic paid him directly.
I've put my mother in touch with the clinic I used and their integrity is surprising. They told her she wasn't a good candidate and they wouldn't perform the surgery for her. Whereas, her local St. Louis doctor was more than willing do to it for $6000.
No. she didn't do it based on her conversations with the Canadian clinic.
Hope this helps, Happy Landings.
