Performing Cataract Surgery. Most cataracts are highly treatable. Cataract surgery is one of the most common surgeries performed in the United States, with approximately 98% of patients experiencing improved vision if there are no other eye conditions present.
Cataract surgery successfully restores vision in the majority of people who have the procedure. People who've had cataract surgery may develop a secondary cataract. The medical term for this common complication is known as posterior capsule opacification (PCO). This happens when the back of the lens capsule â the part of the lens that wasn't removed during surgery and that now supports the lens implant â becomes cloudy and impairs your vision.
