Abstract:
1. Apparatus for the removal of lens tissue, said apparatus comprising: a first handpiece including a laser emitting probe sized for insertion into a lens capsule and radiating a lens therein, said laser emitting probe including a lumen for introducing an irrigation fluid into said lens capsule; and a second handpiece including a vibrated needle for insertion into said lens capsule and emulsifying lens tissue, said vibrated needle including a lumen therethrough for aspiration of emulsified lens tissue and irrigation fluid; a power source for providing pulsed electrical power to the second handpiece; an input for enabling a surgeon to select an amplitude of the electrical pulses; a control console, interconnected with both the first handpiece and second handpiece for controlling simultaneous and sequential operation of the first handpiece and second handpiece and in response to the selected pulse amplitude for controlling a pulse duty cycle of power supplied to the second handpiece, an off duty cycle being controlled to ensure heat dissipation before a subsequent pulse is activated.
