I had RK surgery 7 1/2 years ago. For about 6 years it was perfect. Then I started needing reading glasses which was okay. About a year ago my vision started fluctuating. I didn't know what was happening. I couldn't focus. I went to a doctor who said, "here's a prescription for glasses. come back in two years." I did not get the rx filled. I went to another doctor. It seems that my cornea is flattening even more while I sleep and I cannot see in the mornings. I mean "I cannot see" I cannot focus. It is awful. I have to use 250+ readers. Then I put on progressive glasses that I have just in case. A new doctor has given me contact lenses to try in the mornings or to sleep in so that I can function. I wear them 4 + hours and then don't need them. But everyday is different. It is so unpredictable. I'm so depressed. It is difficult to work and to concentrate. HELP. Has anyone else experienced this? Or heard of it? My doctor is very supportive, but he hasn't had any other patients with this problem.
