A foot controller for use with ophthalmic surgical equipment includes a foot controller having a door . Door covers a surgical switch when door is in a closed position, and door is a shroud for a surgical switch when door is in an open position. A door-position sensor disables activation of the surgical switch , except when the door is in an open position.

Foot controller with ophthalmic surgery interlock circuit and method

A collection reservoir includes a rigid-walled cassette adapted for connection to aspiration tubing The cassette also includes a pair of electrodes positioned so that the electrodes are electrically connectable to a flow meter In operation, the electrodes are exposed to the fluid and tissue being aspirated from the surgical site so that the flow meter indicates a flow rate of the fluid and tissue from the surgical site.

Collection reservoir for use with flow meter control system

An ophthalmic surgical pump system includes a collection reservoir and a venturi pump for creating a vacuum level for aspirating fluid and tissue from a surgical site to the collection reservoir Aspiration tubing connects to each of a surgical handpiece and the collection reservoir A flow meter is electrically connected to either the aspiration tube or the collection reservoir . Control circuitry is connected to the flow meter and to the venturi pump for varying a vacuum level of the pump to maintain a desired flow rate of the fluid and tissue being aspirated from the surgical site.

Aspiration flow meter and control

An ophthalmic irrigation/aspiration venting system that vents a portion of an aspiration circuit by drawing sterile air from a bag. The bag is provided with an air reservoir member to ensure that an adequate air volume is available.

Air venting in ophthalmic irrigation/aspiration system via closed bag system

An ophthalmic illumination system is provided that emits a light that is controllably variable in color. Because the light originates from LEDs, less heat is generated from the emitted light as compared to conventional ophthalmic illumination systems using tungsten or discharge sources.

Variable multiple color LED illumination system

An ophthalmic irrigation/aspiration system that permits selection among or between various venting modes.

Ophthalmic aspiration system with selectable vent method

A method for testing multifocal intraocular lenses and intraocular lenses having designed-in optical aberrations. The method includes the providing of a nullifying lens having an optical zone configured such that light passing through the optical zone and through the intraocular lens is focused at a single plane if the intraocular lens does not contain any fabrication flaws. The invention further includes a nullifying lens constructed such that light passing through the nullifying lens and through an intraocular lens is focused at a single plane if the intraocular lens does not contain any fabrication flaws.
