I had cataracts and had both eyes implanted with Rezoom lens. Since the second operation, I have had double vision. This is now over four weeks. When does it go away. At first, I had to hold on to my son's shoulder to walk in the store, like the blind walk. However, it is somewhat better, as I can see most of the time, but I have not attempted to drive at night. I see halo's around all lights. I have not attempted to play tennis anymore, as I do not know which ball to hit. After paying additional for the lens (over what insurance did not cover) I am quite disappointed. Is it the lens or the doctor?
