I had Femto Lasik because of high astigmatism in 2008 and it was one of the best decisions I ever made. Despite the warnings from my FAA AME and usual yada dada on the Internet, I decided to go for it and have no regrets.
I mostly did it to improve quality of life (sports etc) away from the controls. I was grounded for a while and after my surgeon declared me fully functional again I had to inform the FAA and show up at my AME. I am on FAA and HKCAD first class medical again and the limitation of 'wearing corrective lenses or spectacles and second set available' was removed...
