Though there are not many complications, there is a possibility of a “secondary cataract”. In a few cases, months or years after cataract surgery, the posterior portion of the lens capsule that is left inside the eye during surgery for safety reasons becomes hazy, causing vision to again become blurred. This “secondary cataract” (also called posterior capsular opacification) usually can be easily treated with a less invasive follow-up procedure called a YAG laser capsulotomy. In most cases, this 15-minute procedure effectively restores clear vision.
