Paula, my Mom has had a cataract operation in both of her eyes. The operation is not painful at all and she was awake through the whole thing. After the op, there are drops to put in her eyes but in a week, she will "see" a big difference. This type of operation is performed on thousands every day so no need to worry....although that's easier said than done especially when it's your Mother. Good luck and please keep us posted as to when it will happen.
