I don’t mean to appear dumb, but I have poor vision and am legally blind in right eye due to scarring from radial keratotomy surgery some 40 or so years ago! Had a cornea transplant in that right eye in 2003 but unsuccessful due to the incisions in my cornea opening up and requiring cornea stitches leading to severe astigmatism. Now, as far as the left eye, I had cataract surgery in left eye a few years ago but to my knowledge no lens to give me better vision was implanted! ?????
