Abstract
A system for performing surgery on a patient's eye includes a handpiece constructed for insertion into the eye, a control module, and a foot pedal module. The control module includes at least one control arranged for setting at least one parameter of operation of the handpiece (e.g., aspiration rate, intensity of phaco-power, etc.). The foot pedal module includes a foot pedal with which operation of the handpiece is controllable in accordance with the parameter set by the control in the control module. For example, the foot pedal may be used to vary the aspiration rate or the intensity of phaco-power up to the maximum set by a control on the control module. The foot pedal module includes circuitry for controlling operation of the handpiece in response to depression of the foot pedal and in accordance with the parameter set by the control in the control module. That is, processing circuitry is located in the foot pedal module rather than the control module, which enables the control module to be relatively compact.
