The present invention provides a system and a method for managing occlusions and reducing eye tissue damage during phacoemulsification surgery. More specifically, the present invention provides automated control of the application of ultrasonic energy to a partial or full occlusion of a surgical tool. The present invention measures the vacuum pressure and automatically adjusts the application of ultrasonic energy when the vacuum pressure indicates an occlusion or an occlusion break.

Systems and methods for automated phacoemulsification

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.
