But each eye must be able to correct to 20/20 individually, otherwise you'd need a waiver. Lots of people with strong prescription glasses, and a variety of laser surgeries flying in the US.
Overseas, it can be a very different story, potentially more stringent. I'm moving this another forum for that reason.
I had PRK and have worked in China and now work in Europe since I had the surgery. In the States it was pretty simple. In China and in Europe I had to do a contrast sensitivity test in order to qualify. The contrast sensitivity test is just to see how well you can see in low light/low contrast settings.
