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.

An apparatus for extracting fragments of cataract tissue comprising: a probe with a tube having an aspirating opening and an irrigating opening at one end thereof adapted for insertion into the eye through an incision for supplying an irrigating liquid to the interior of said eye through said irrigating opening and aspirating that liquid and fragments of cataract tissue through said aspirating opening; and means for dislodging fragments of cataract tissue at said aspirating opening which have not passed through said aspirating opening including a member mounted on an exterior surface of said tube adjacent to said aspirating opening for controllable movement into contact with a fragment which has not passed through said aspirating opening for applying a force to the fragment to break up the fragment and means for moving said member into contact with the fragment, said means for dislodging fragments of cataract tissue further including means for vibrating said tube.
