Having the rear capsule become cloudy is pretty normal following cataract surgery. There is a YAG laser procedure called YAG capsulotomy where they put a hole in the area that is clouded up. The prosthetic lense stays in place and the cloudiness is gone. You can expect a floater that shifts around following the surgery.

I got cataract surgery in one eye a few years ago. I am much younger than the average patient. It's not as good as what you have naturally when you are young but it sure beats what you have with a cataract. In my case, the floater did become mostly unnoticeable within a year. It didn't really impede my daily life before that.
