After cataract surgery or other ocular operations, after-effects sometime occur which interfere with vision. One is the clouding or opacification of the posterior lens capsule (the supporting tissue behind the lens implant). If your vision is impaired by this opacification, your surgeon may use what's known as a YAG laser. With a YAG laser posterior capsulotomy, converging laser beams are aimed directly at the hazy lens capsule, and as they meet they cut a small hole in the capsule. This allows light to pass through again, restoring your vision to the way it was not long after your initial cataract surgery. This procedure only takes a minute or two and there is no need to use a blade to make an incision or cut into the eye with this laser.
Other uses for the YAG Laser include:
