I had radial keratotomy (RK) in 1984- vision was great for about 20 years and then I needed glasses which has not been a problem. Now that I am in my 70’s, I need cataract surgery. I had a severe dry eye problem which has been corrected and according to my ophthalmologist my eyes are now very healthy and he would approve cataract surgery. What are the differences in the surgery with someone who had RK versus someone with a “normal” cornea that has never been altered with RK? Are there more risks involved with the surgery itself, any possible side effects that would be a continued problem after surgery? Do you recommend any reading materials that might give me more information? Thank you for your time.
