Why do I need distance glasses when I had radial keratotomy over twenty years ago?
MAR 20, 2016
I had radial keratotomy (or RK, a surgery to correct nearsightedness) in 1994 with great results. I have noticed over the last year or so that I am becoming nearsighted. I am 60 and figured I would be needing reading glasses, not distance glasses. I'm concerned about what is happening and don't have access to the doctor who performed the RK. Is this normal? Should I be concerned?
This to be expected by both the continued change in shape of the eye due to RK and age. RK tends to give you a better depth of focus, so reading vision can remain or get better into your ‘50s in some cases. Distance vision tends to get worse because the RK flattens the central cornea—this is even worse at high altitudes as in visiting the mountains in Colorado. Eventually the hardening of the lens that occurs with age will lead to cataract. When the cataract is removed and replaced with the artificial lens implant, this can help with the disparity between distance and near. Please go to an ophthalmologist (it does not have to be the one who did the surgery) and get a baseline "view" of what is going on.
