A secondary cataract, also known as posterior capsule opacification (PCO), is a condition that can occur after cataract surgery. It happens when the back portion of the natural lens capsule, left intact during the initial surgery to hold the artificial lens in place, becomes cloudy over time.

Symptoms

This cloudiness can cause vision to become blurred again, similar to the symptoms of a cataract.

Treatment

Fortunately, secondary cataracts can be easily treated with a procedure called a YAG laser capsulotomy. During this outpatient procedure, a laser is used to create a small opening in the cloudy capsule, restoring clear vision without the need for an additional surgery.
