I am a 45 year old male. 25 years ago, I had radial keratotomy on both eyes. After a year, I had for the second time in my left. Later, BCVA in left became 9/10 and right 10/10. Now over a month, I am experiencing a blurry vision in the left with occasional headache and left eye pain. Three weeks ago, I had an eye examination and the left eye vision was 4/10 and right 9/10 not correcting both with glasses. My doctor informed me that there is a higher degree of corneal opacity in the left eye and less in the right. He also saw a coloring matter in the cornea. The RK, 4 incisions, were performed at the age of 16 and now I am 45. My doctor told me that my blurry vision is due to abnormal cornea and the only solution for my case is to try to fix the vision with contact lenses. The results were negative when I tried all kind of lenses such as scleral, soft, hard, etc., the left was only 6/10 and 9/10 right. My doctor said that there is no chance for PTK or corneal transplant. What treatment can I opt for? I have attached my investigation reports, so you can have a better understanding of my problem. Any suggestion will be helpful. I would like to know, is there a chance of glaucoma? Thanks and looking forward for your response.
