Capsulotomy.

The development of posterior capsule opacification secondary to extracapsular cataract extraction is a common occurrence. The patient complains of decreased visual acuity, glare, and sensitivity to light. The YAG laser posterior capsulotomy has become standard treatment for this anomaly: an opening is created in the opacified posterior capsule, which immediately improves visual acuity. This review describes the indications, preparation, procedure, follow-up, and complications associated with using a yttrium-aluminum-garnet (YAG) laser to perform capsulotomy.
