Posterior Capsule Opacification
The lens capsule is the thin, elastic-like bag that holds the intraocular lens (IOL) in position after cataract surgery. During the operation, the front (anterior) portion of the lens capsule is carefully opened and the cataract is removed. The IOL is inserted into the remaining (posterior) portion of the capsule.

The remaining portion of the capsule becomes clouded in about 25% of cataract surgery patients. When this occurs, patients experience symptoms similar to those from the original cataract. That's why posterior capsule opacification is also known as secondary cataract.

SIGNS AND SYMPTOMS
•Gradual decrease of vision
•Blurred vision
•Glare from lights and sun
DETECTION AND DIAGNOSIS
The doctor can diagnose posterior capsule opacification during a routine eye exam using a slit lamp microscope. It is more easily detected if the pupil are dilated. Potential acuity testing is often performed to determine the expected improvement of vision.

TREATMENT
A simple procedure called a YAG posterior capsulotomy is performed to restore vision lost from the clouded capsule. The YAG is a type of cold laser used to create a small opening in the center of the capsule, allowing a clear area for light to enter the eye. The procedure is painless, requires no anesthesia, and has very little risk since no incision is required.

After the dilating drops wear off from the procedure, most patients notice an immediate improvement in vision. The improvement each person experiences is dependent on the extent of the capsular clouding and the overall eye health.
