phacoemulsification

 [fak″o-e-mul″sĭ-fĭ-ka´shun]
a technique of cataract extraction, utilizing high-frequency ultrasonic vibrations to fragment the lens combined with controlled irrigation to maintain normal pressure in the anterior chamber, and suction to remove lens fragments and irrigating fluid.

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.

[sup][6] revealed that transplanted corneal grafts after ECCE had a lower endothelial cell loss rate than that of transplanted corneal grafts after phacoemulsification. The endothelium should be carefully evaluated when choosing a surgical technique for cataract removal in both normal and transplanted corneal grafts.
