Laser posterior capsulotomy, or YAG laser capsulotomy, is a noninvasive procedure performed on the eye to remove the opacification (cloudiness) that develops on the posterior capsule of the lens of the eye after extraction of a cataract.
Laser posterior capsulotomy is performed with Nd:YAG laser, which uses a wavelength to disrupt the opacification on the posterior lens capsule.
It does not occur when an anterior chamber lens is implanted, because in this procedure the capsule is usually extracted along with the cataract, and a lens is attached to the iris in the front part of the eye, called the anterior chamber.
