Posterior Capsulotomy Surgery (YAG) – Overview

In some cases, the part of the lens covering that supports the IOL (called the capsule) can become cloudy several months or years after the first cataract was removed. This is called an “after cataract” or “secondary cataract.” If this occurs and blurs your vision, our doctors will make an opening in the center of the cloudy capsule with a laser to allow light to pass through the lens properly again. This procedure, called a posterior capsulotomy, takes about five minutes in our doctor’s office and requires no recovery period. Fortunately, a YAG laser can treat posterior capsule opacity safely, effectively and painlessly. This procedure, known as YAG laser capsulotomy, often can be performed in your doctor’s office.

YAG laser capsulotomy involves just a few simple steps: 

  • Usually the eye is dilated before the procedure, with dilating eye drops.                                           
  • A laser removes the hazy posterior capsule from your line of sight without making an incision or “touching” the eye.
  • anti-inflammatory eye drops following the procedure.
