I had it done 12 years ago after wearing glasses for 10 years. I had each eye done individually. I have had no problems with vision for all that time and see better than 20/20 in my left eye which was my worst eye.
The procedure was painless for me and gave me great results. I have 2 friends that had it done at a different place at a much cheaper price. One had diabetes and the procedure didn't work 100 percent the first time and had the choice to go back to fix it but didn't. The other person had some problem with their eyes that he said would eventually make him color blind. His vision improved but he did not go back to try a second time.
A woman that also went to the less expensive place got it done about 7 years ago and also had success like me.
