I had it done after going to a lot of different places and reading a lot about the procedure. There is different versions of the same procedure as well different procedures and different technology out there.
I choose TLC in Toronto. They were much, much more expensive than $400 CND per eye but their technology was more advanced and was the best fit for my needs. Strong prescription (-7 per eye), astigmatism, large pupils, one pupil that is slightly large than the other due to a sports injury, I had a lot going on with my eyes that made it far from routine.
Anyhow, for me the end result was amazing, life changing. I'm so glad I did it. I'd strongly recommend it for anybody who's eyes are bad enough to warrant the slight risk and expense. But you really do need to research who does it.
Specifically about risk - In the lobby of TLC offices they had a book with all the stats. Chances of this, chances of that and the numbers were all really good. Everyone possible bad occurrence had really insignificant risk. It was always numbers like 1 in 100,000, 1 in 55,000 etc. and I also recall that each possible pitfall had TLC rate of complications beside it and in every case it was 0.
