A vitrectomy apparatus is provided, including a pressure source, a cut valve connected to the pressure source, the cut valve configured to be turned on and off to provide pressure to selectively extend and retract a vitrectomy cutting device, a sensor configured to sense pressure provided from the cut valve, and a controller configured to control operation of the cut valve based on pressure sensed by the sensor. The controller is configured to monitor pressures encountered and alter cut valve timing based on pressure conditions previously encountered.

Methods and apparatuses for automatically switching different aspiration levels to an ocular probe are disclosed herein. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level. Control feed back of the pumps may be varied according to set thresholds.

Automatically switching different aspiration levels and/or pumps to an ocular probe

Methods and systems for automatically pulsing different aspiration levels to an ocular probe are disclosed. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level, and applied to the probe in a pulsed manner.

Automatically pulsing different aspiration levels to an ocular probe

The present invention relates generally to providing pressurized infusion of liquids and, more particularly, is directed to providing a stable and pressurized flow of irrigation fluid to the eye during surgery.

System and method for providing pressurized infusion

A vitrectomy apparatus is provided, including a pressure source, a cut valve connected to the pressure source, the cut valve configured to be turned on and off to provide pressure to selectively extend and retract a vitrectomy cutting device, a sensor configured to sense pressure provided from the cut valve, and a controller configured to control operation of the cut valve based on pressure sensed by the sensor.

Vitrectomy surgical apparatus

A phacoemulsification system and method, and a surgical foot pedal device, system and method. The present invention may include a console comprising a plurality of modes for at least one physically associated surgical instrument, and a foot pedal communicatively associated with said console and suitable for varying ones of the plurality of modes. The foot pedal may include a housing comprising the communicative association, and comprising at least one potentiometer and at least two top switches for the varying of the ones of the plurality of modes, a treadle rotatably mounted within the housing and suitable for depressing the at least one potentiometer, and at least two side switches movably associated with the treadle for the varying of the ones of the plurality of modes.
