Berkeley Bioengineering Ocutome invented by Conor O’Malley, MD and Ralph Heinz, pneumatically operated, axial motion, bellows actuated. The cutter, infusion cannula and endoilluminator utilized separate 20-gauge ports. Three-port vitrectomy rapidly replaced the VISC and RotoExtractor because infusion was always available, the endoilluminator could be used with scissors, forceps, extrusion cannulas, endophotocoagulation probes, and other tools.
