black spots after cataract surgery

My 85 year old mom had cataract surgery about 1 month ago and she has been seeing black spots eversince. The spots are both small and big. She was told by her surgen that after few weeks she should be better. But after 1 months she has not improved. What should she do and what is the treatment for this black spots?

There are a number of causes of black spots. The two most common  1. vitreous floaters, black spots that move when the eye moves and are present most of the time  2. negative dysphotopsia that are due to the IOL, especially multifocal IOLs.

There are other causes. If they are getting worse ask for a second opinion
