Abstract: Disclosed is a surgical footswitch, comprising a base, a pedal mounted to the base, and a variable air capacitor mechanically coupled to the pedal, such that movement of the pedal is operative to vary the capacitance of the variable air capacitor. The footswitch further comprises a capacitance-sensing controller circuit electrically connected to the variable air capacitor and configured to measure a capacitance of the variable air capacitor and to produce a control signal based on the measured capacitance, such that the control signal reflects a position of the pedal or a change in the position of the pedal, and a wireless interface electrically connected to the capacitance-sensing controller circuit and configured to wirelessly relay the control signal to a surgical console.

Abstract: Active noise cancellation is employed to address unwanted acoustical noise generated by various equipment associated with an ophthalmic surgical system. Active noise cancellation may be used within a chassis of the ophthalmic surgical system, within an air compressor used with the ophthalmic surgical system, and within a reciprocating surgical probe used with the ophthalmic surgical system.
