phacoemulsification 

Procedure for removal of the crystalline lens in cataract surgery, which consists of emulsifying and aspirating the contents of the lens with the use of a low-frequency ultrasonic needle inserted into the eye near the limbus. This technique usually produces more rapid wound healing and early stabilization of refractive error with less astigmatism, due to the small incision. However, this technique may damage the corneal endothelium if excessive ultrasound is used. Following removal of the lens cortex and nucleus, an intraocular lens may be implanted within the remaining lens capsule. The lens is folded and inserted through a small incision (e.g. 3.2 mm) using a special injector. This procedure is preferred over other cataract extraction techniques due to both the rapid wound healing and the lower incidence of potentially vision threatening side effects (e.g. retinal detachment). See after-cataract; biometry of the eye; cataract extraction; intraocular lens; iridectomy.
