After the Ophthamologist looked into my eyes, he told me that both of my IOL's were moving in the membrane, the right more than the left, and that's why I have the visual distortions. He did laser surgery to open the hole in the back of the membrane on the right eye as far as he could which improved the situation somewhat, but didn't solve the problem. He suggested surgery, but also told me to wait and see if it becomes worse. He said, "I am not going to mess with a 20/20 eye, have it checked every three months" Is this the right approach?
I think it highly unlikely the IOL is moving. The IOL is in the capsular bag and the bag is held in place by small ligaments (zonules). There are numerous causes of the problem you describe. One common is the capsular bag turning cloudy (not the IOL). I suggest you see your eye MD surgeon to evaluate the possible causes and treatments.
