Abstract
An instrument for ophthalmic surgery to remove cataractous-lens tissue has an elongate stem which enables external manipulation at its proximal end and which at its distal end presents a cutter adjacent a transiently open cavity into which cut or chopped tissue can be manipulated. The instrument provides for selectively operated closure of the thus-loaded cavity, an event which must occur before laser radiation can issue within the cavity, in fragmenting or emulsifying reduction of cut or chopped tissue within the cavity. Thus, reduced, the fragmented material is extracted by an aspirating flow of liquid. This process is repeated until the capsulary bag has been cleared of cataractous material, be it nuclear or cortical.
