My wife had cateract surgery about four years ago. Ever since the surgery she has seen a triple image of light sources. She has had three doctors look and say that the lens looks fine. However, nobody has seemed to want to try to find out what the problem actually is. She now needs a capsulectomy, and we are afraid to proceed with that until we can figure out what the ghost image problem is. What tests can be done besides a simple visual inspection? She even has her retinal photos, and on the image that shows the exterior of the eye you can see the light source and two ghost images on the eye that has had the lens replacement.
