摘要：
A vitrectomy apparatus (300) is provided, including a pressure source (310), a cut valve (316) 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 (315) configured to sense pressure provided from the cut valve, and a controller (320) 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.
