Posterior Capsular Opacification
Posterior capsular opacification (PCO) is a common problem that can occur after cataract surgery. The capsule that is present behind the lens becomes hazy and needs treatment to see well again.
Normal Capsule
During cataract surgery, the cloudy natural lens of the eye is removed and replaced with an artificial lens called an intraocular lens (IOL). The IOL is typically placed in a thin, transparent capsule that surrounds the natural lens, called the lens capsule.
Opacified Capsule (PCO)
PCO occurs when cells from the natural lens that were not removed during cataract surgery start to grow and multiply on the back surface of the lens capsule, causing cloudiness or opacification. This can cause blurry vision, glare, and difficulty seeing in low light conditions.
Treatment: Yag Capsulotomy
A YAG capsulotomy is performed using a specialized laser called a YAG laser. The laser creates a small opening in the cloudy posterior capsule, allowing light to pass through and restoring clear vision. The procedure takes a few minutes and is usually painless, with minimal recovery time. The procedure is typically done on an outpatient basis and does not require any incisions or anesthesia.
Patient View Yag Laser
This is a patient's view of the Yag Laser. The chin sits on the chin rest with the forehead against the band. There are handles to hold for stability. A contact lens is usually placed on the eye for stabilization as well as improved accuracy.
The Treatment
After a YAG capsulotomy, the cloudy capsule does not reform, and the procedure generally provides permanent improvement in vision. It is considered a safe and effective treatment for PCO. However, as with any medical procedure, there are potential risks and complications, which should be discussed with your eye doctor.
