Ultrasonic and cryogenic 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 and cryogenic instrumentation include hand-held instruments with the cryogenic instrumentation adapted to first freeze the cataract lens and after the cataract lens has unfrozen the ultrasonic instrumentation is adapted by 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 lens is removed.
