If you are going to blame anyone, I would blame your surgeon who performed the initial procedure. I had PRK done to my eyes when I was a firefighter over ten years ago and I still see great. However, my doctor clearly explained the pros and cons of each procedure (LASIK/PRK). You doctor should have measured the thickness of your wife's cornea as well. This would have let her know if she was a good candidate for the LASIK surgery. With LASIK, creating that "flap" is an incision of the epithelial layer of the eye. In most people this does not 100 percent heal. This should have been clearly explained. I hope the best for your wife and a speedy recovery.
