METHOD AND APPARATUS FOR OCULAR PERFUSION

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.
