YAG Capsulotomy
A "YAG" is a procedure used to treat posterior capsular opacification (sometimes known as a secondary cataract). This is a clouding of the remaining capsular tissue that develops postoperatively in as many as half of cataract removal operations. Symptoms of posterior capsular opacification are similar to those of a cataract, including blurred vision and increased glare. The procedure takes seconds, and once performed will never need to be done again.
