phacoemulsification

A surgeon performs phacoemulsification on a patient's eye.

Definition

Noun: - A surgical procedure for cataract removal: A modern, minimally invasive form of extracapsular cataract surgery. In this procedure, an ultrasonic probe is used to break the cloudy lens (cataract) into tiny fragments, which are then suctioned out through a small tube. The natural lens capsule is typically left intact to support a new artificial intraocular lens.
