Abstract:
1. A handpiece system for multiple phacoemulsification techniques, said handpiece system comprising: a housing having a distal end adapted for scalably and releasably engaging a plurality of at least two different interchangeable nose cones; a sonic generator disposed within said housing; a horn having a body connected to said sonic generator and a needle for radiating sonic energy into an eye for fragmenting eye tissue, said horn including a lumen, passing through the needle and body, for aspiration of fluid and fragmented eye tissue; a first interchangeable nose cone sealably and releasably engaging the housing distal end and configured to perform a bimanual phacoemulsification procedure in which irrigation fluid does not pass over the needle and into the eye; and a second different interchangeable nose cone sealably and releasably engaging the housing distal end for establishing an annulus surrounding said needle, said second nose cone including an inlet for receiving irrigation fluid and enabling the irrigation fluid to pass over said needle and into the eye.
