Occurring in a small proportion of patients, posterior capsular opacification (PCO), also known as “Secondary Cataract” or “After-Cataract,” occurs when the lens capsule (the membrane that supports the lens implant) becomes cloudy following cataract surgery.
The artificial lens implanted in your eye during cataract surgery is clear allowing light rays to pass through and focus precisely on the retina. The eye’s lens is located inside of a thin membrane, like a pocket, called the capsule. Occasionally, the capsule that holds the IOL can become cloudy. As with a cataract, when light passes through this cloudy capsule, it no longer focuses clearly on the retina; and, objects appear hazy or blurred.
Laser Treatment for Secondary Cataracts
With YAG laser capsulotomy your ophthalmologist will use a laser to create an opening in the back of your eye’s cloudy lens capsule. Light can pass through the lens and focus properly on the retina allowing you to see clearly again.
