ABSTRACT:
A method is disclosed in which the suctioning of materials from a surgical zone, such as the human eye, is automatically controlled linearly by means of a pressure transducer continuously sensing the vacuum level of a debris receptacle (for collecting suctioned materials from the surgical zone) when material is being suctioned from the zone. The vacuum level in the debris receptacle is linearly varied when the vacuum level in the receptacle is either raised or lowered depending on the suctioning requirements from the surgical zone and whether or not the vacuum level in the receptacle is greater or lower than a previously determined and desirable vacuum level. The vacuum level of the receptacle may, in part, be controlled and varied, by means of a foot pedal operated by the surgeon.
