This apparatus is a device for removal of cataracts from the eyes of patient. The apparatus includes a hand piece, with an irrigation water line, a vacuum line and a power line provided therein, are all connected with the hand piece. Within the hand piece the vacuum line is attached to a tube, identified as the horn, concentric with the outer shell of the hand piece. Through a hooks and slider joint, bayonet type or threaded joint in the front end, the horn connects with a surgical needle. At the front end of the irrigation tube it discharges water into a chamber, which irrigation water passes between the needle and an outer sleeve and into the anterior chamber of the eye. Ultrasonic waves transmitted to the horn are conveyed to the tip of the needle where the axial vibrations of the tip may be used to comminute cataract material.
