Phacoemulsification Units, Cataract Extraction

Definition : Ophthalmic surgery units designed for removal of cataractous lenses by the insertion of a probe that cuts and emulsifies the lenses using ultrasonic waves (phacoemulsification). These units consist of a hollow probe (i.e., a phaco probe) that includes an irrigation sleeve, an oscillating tip that converts electric energy into ultrasonic waves, and a channel for aspiration of lens fragments; the units also include a vacuum pump and controls for the output levels, irrigation rate, and mode of operation. Phacoemulsification units are used in ophthalmic offices for cataract extraction surgery.
