Your best bet is likely to get an independent second opinion. How long has it been since your surgery? What is your glasses prescription and what is your vision with them on?
As for seeing the edge of your lens - I had this problem after cataract surgery six years ago and my surgeon too tried to pretend he didn't know what I was talking about. It is called dysphotopsia a very disappointing result after cataract surgery. I have just had my second eye done a week ago by a different surgeon and he was able to use a lens that has avoided this problem. Hope you can find a solution to the problems you are facing. Seeing the edge of the lens and loss of peripheral vision are the symptoms I still have six years post surgery. Artificial lighting makes the symptoms worse.
I also have this after my cataract surgery. Both eyes like have a spasm effect when I am in sunlight or florescent light. It feels like my lenses are moving across my eyes when I look to the side. My surgeon has brushed it off and the other doctor said I am seeing the edges of the lens and my brain will have to get used to it and it will be better. Well my brain never got used to the PVD flashes and floaters 5 months ago. None of the people I know ever had any problem with "seeing the edges of their lens. I am so happy to be able to see clearly but this is really bothersome and slightly nauseating as my vision keeps shifting all over the place and as a photographer it as really messed me up for outdoor shooting. Did yours ever get better and how do you get a straight answer from your doctor.
No, I asked again and they said I just had to give it time for my brain to adjust. It hasn't. Being under florescent lights is the worse. I asked about going to see another Dr at the university but they kind of brushed that off also and just keep telling me it is normal. Then why am I the only one of the people I know that have this issue.
