What is a YAG?

YAG capsulotomy is an outpatient laser procedure performed on an eye to improve blurry vision caused by a posterior capsular opacity. A posterior capsular opacity is a painless hazy film that can form behind a lens implant after cataract surgery. Other names for this condition include secondary cataract, after-cataract, posterior capsular membrane, or posterior capsular fibrosis. The opacity develops in the posterior capsule, the clear membrane that supports the lens implant after cataract surgery. It may form in as little as one week to several years after routine, uncomplicated cataract surgery. Common symptoms are decreased vision, haze, distortion, and glare. Vision may be similar to what it was when the cataract was present. The membrane is not dangerous and will not cause any permanent loss of vision.

YAG is short for yttrium, aluminum, and garnet, which are the elements used to give the laser its energy. This particular laser can be accurately focused to create a precise central opening in the cloudy posterior capsular membrane without any incisions. The YAG laser is attached to a microscope that’s very similar to the one used by your eye doctor to examine your eyes in the office. This allows the procedure to be performed comfortably in the sitting position. Anesthetic drops are used to numb the eye, and the procedure only takes a few minutes to perform. Typically there is no discomfort, and normal activities can be immediately resumed. Vision improves within the first few days. The procedure is highly successful, however there are very small risks, including floaters and the rare chance of a retinal tear or detachment.
