摘要： Ocular perfusion during intraocular surgery of the anterior or posterior ocular cavity is optimized through the method of using a gas pump having a discernible and controllable output pressure to pressurize a reservoir of liquid infusate, which is supplied under pressure to a surgical infusion instrument for perfusion of the selected ocular chamber (Gas Forced Liquid Infusion, GFLI). The infusate selection and the infusate pressure can be controlled with a high degree of accuracy and both can be rapidly varied by audible command. Preferentially a human sensible indication of pressure is constantly available at the gas pump.

摘要： 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.
