DEAR DOCTOR K: I am having cataract surgery in a few weeks. Can you describe the possible complications?
DEAR READER: A cataract is a clouding of the normally clear lens of the eye. As the condition worsens, you may experience blurred or dim vision, increased glare, double vision, nearsightedness and worsening night vision. Surgery is the only effective cure. During cataract surgery, the doctor removes the clouded lens and replaces it with a clear artificial lens. (I've put an illustration of the procedure at the end of this post.)
