I ve had keratitis in my left eye, due to having the shingles, for over 10 years. In 2013 I had cataract surgery on both eyes. Everything seemed to be doing fine until the fall of 2016 when I noticed objects were blurry in the left eye which had keratitis. Now I have the same problem in my right. My question to you is, Could it be a problem having surgery on my left eye again?
