I guess I did not realize a cornea can do this on its own. Well with that you would not be a candidate for laser surgery, and also do not wear contact lenses. The danger must be that for any reason a perforated cornea may cost you your vision. The good thing about a corneal transplant is that the cornea has no nerve or blood supply. The cornea is the only tissue in the body that can be transplanted without fear of rejection.
