At least that is what my ophthalmologist says. To summarize:
Age 8 -- got glasses
Age 9 -- got contacts
Age 40 -- got LASIK. I was at 20/400 and after LASIK life was wonderful. I was 20/15 in the right eye and 20/50 in the left. I could have had my left done again, but nearsighted in one and farsighted in the other worked for me.
Age 48 -- got shingles on the right side of my face. I got over that without too many problems, but developed iritis in my right (far vision) eye. Many weeks of steroid eye drops starting 6 times a day and tapering fixed that, but my vision never got back to 20/15.
Now -- a few weeks ago I developed blurry vision in my right eye, like a film. I go in to the doctor today and after spending lots of time looking at my eye said he had never seen what I have -- basically a film over my cornea. He said it is sometimes seen immediately (like a week) post LASIK but we are at 12 years and counting for me. So now I am back on 6 times a day steroid drops and see him again in a week. My vision is at the point I cannot drive. Thankfully my near vision is fine so I can work, read and do internet stuff.
