A METHOD AND A SYSTEM FOR PERFORMING CATARACT SURGERY

摘要

A system for surgically removing a cataract (20) from an eye (10) includes a cryomanipulator (50) having a body (52) and a head (66) with a cryogenic tip (72) for freeze-gripping and manipulating material in an eye. The cryomanipulator may include a surgical tip (70), a heating device (74) and an irrigation/suction sleeve (54). The system further includes a cataract removing device (CRD) (204) for breaking up the cataract while it is frozen by the cryomanipulator. The CRD includes a drilling unit (230) having a rotatable drill blade (246) for breaking up the caractact and a housing having irrigation irrigation and aspiration conduits (256). A method of using the system includes the freeze-gripping and breaking up of the cataract followed by irrigation and aspiration of the fluid and the cataract fragments with the CRD and/or the cryomanipulator.
