Posterior Capsular Opacification, Secondary Cataract, (after cataract)


Posterior capsular opacification (PCO), also known as secondary cataract or after cataract, is a condition in which the back part of the lens capsule, which holds the artificial lens in place after cataract surgery, becomes cloudy or opaque. This can cause a decrease in vision and may require further treatment to restore clear vision.
