I had cataract surgery done which took 3 to 4 times as long as normal. By this taking that long the numbness had wore off half the way though and the pain was very painful. I told them I was in a lot of pain and her answer was we will be done in a little while. This was my mistake for taking Dr. Burton's word that she was very good and not checking her experience out myself. I now have to use reading glasses for every thing within 4 feet of me. I have never wore glasses in my 70 years before. It is very different to do normal things but I guess I will have to deal with it the rest of my life. Not very satisfied with results.
