Vision Correction Surgery
I, for one, with 20/400 in the left eye and 20/70 in the right and a bifocals wearer, would love to have vision correction surgery, but I don't fancy the outcome if it goes wrong. And, it can. Check out this
website and you'll see what I mean (sorry - bad pun).
Notwithstanding all the frightening effects of eye surgery gone bad, I, as a pilot, would be especially afraid of glare, night vision loss, and double vision.
Another point is vision correction surgery won't do much for you if you're at the age where you need reading glasses. Some eye surgeons can set up monocular close vision to eliminate that need, meaning that you would use one eye only for close vision. In my $0.02 opinion, that doesn't make sense, so, for close vision, you'll still need reading glasses, so what is the point of getting it? The idea is to eliminate the need for glasses and/or contacts altogether.
There are non-surgical procedures for improving vision, such as
Ortho-K. Also see
this story. Ortho-K involves one wearing a series of contact lenses to change your cornea to improve your vision. It's actually an older procedure, although the contact lenses have improved. You still have to wear them every night or your vision will regress to where it was. I could live with that. I asked my optometrist about the treatment and she wasn't too keen about it. She also said that Ortho-K does not eliminate the need for reading glasses.
Finally, from what I understand, all you need to have a corrective lens restriction removed from your medical is to have your opthalmologist fill out the FAA Report of Eye Exam form and send it in to Oklahoma City. I also understand that the airlines have really relaxed their anti-eye surgery bias. Most care only that you have your First. That is a major change from even ten years ago.
Hope that helps. Good luck with whatever you decide to do.
