Abstract
A cutting tip for a rotary motor-driven cutting instrument for cataract surgery consists of a hollow stationary tube and a tubular cutter journaled therein and projecting therefrom, the cutting tip being open at its end and having concentric axially directed arcuate cutting edge portions. An annular passage extends between the concentric tubes, and the stationary tube has an orifice in the side close to the tip. An irrigating fluid is adapted to be discharged through the side opening of the stationary tube, and a suction connection to the internal tube is effective to remove severed tissue through the hollow rotatable internal cutter.
