ABSTRACT:
Ultrasonic instrumentation for the removal of unwanted tissue material from an animal, such as a human, and more particularly, adapted for the removal of cataracts, in surgical operations. The ultrasonic instrumentation includes a hand-held instrument adapted to have a vibrating tool to reduce the volume of the cataract and thereafter, through the simultaneous introduction of a fluid and creating a flow, the cataract mass exits through the incision around the vibrating tool until all of the unwanted tissue forming the cataract is removed. The cataract may be removed substantially intact or by forming a plurality of masses.
