A mains electricity (AC-powered) ophthalmic device, that is a component of a system, that generates the energies (e.g., ultrasonic, piezoelectric, high frequency current) delivered through handpieces/tips that are introduced through an incision(s) made in the eye, for the purposes of performing combined phacoemulsification and/or vitrectomy (the removal and replacement of cataracts and/or the vitreous in anterior and posterior segment surgical procedures). It will typically be activated by the surgeon using a foot-switch and may include an irrigation/suction system for the removal of debris, a tamponade system (e.g., silicone and air), a diathermy device, and an intraocular illuminator.
