During cataract surgery, your doctor replaces the clouded, blurry lens with an artificial one to correct vision. However, after surgery, many people experience a gradual clouding of vision within the first few years. This condition is known as after-cataract or secondary membrane.
A procedure called a posterior capsulotomy, using an Nd: YAG laser, can be performed to remove the back lining of the lens capsule and let light pass through to the retina. The laser creates an opening in the back lining and helps remove cloudiness.
The capsulotomy is a painless procedure that only requires the same numbing drops used during a routine eye exam. It is considered a safe procedure and most people experience improved vision and reduced glare right away.
