Description

ABSTRACT:
Apparatus and method for extracting cataract tissue in which the cataract is first softened by focusing laser radiation thereon and subsequently a tube inserted through an incision to a position adjacent the cataract. An irrigating liquid is supplied through one portion of the tube and the liquid and cataract fragments removed via an aspirating opening adjacent the tube opening. Fragments which do not readily pass through the aspirating opening are dislodged by vibration or broken up by a paddle like member pivotally mounted adjacent the aspirating opening to engage the fragment and apply a force to break up the same.
