<p>Ocular perfusion during intraocular surgery of the anterior or posterior ocular cavity is optimized through the method of using an air gas pump (13) having a discernible and controllable output pressure (18) to pressurize a reservoir of liquid infusate, which is supplied under pressure to a surgical infusion instrument (29) 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 (37). Preferentially a human sensible indication of pressure is constantly available at the gas pump (13).</p> |
