ABSTRACT:
Apparatus for us in intraocular surgical procedures utilizes a plurality of flexible conduits and a control valve to selectively supply an infusion cannula with either fluid or air. The air and fluid are pressurized for infusion by a continuous infusion air pump and supplied to the valve by parallel lengths of flexible tubing. The apparatus may be used to monitor and control the infusion pressure or to switch the infusion agent in a minimal time.
