<p>A method useful in a process for cataractous lens removal for operating phacoemulsifier apparatus having a vacuum pump and a fluid irrigation pump in order to simultaneously control vacuum, for aspiration, and fluid flow, for irrigation, to a phacoemulsifier handpiece (16). The method includes selecting a vacuum limit for aspiration; selecting a fluid flow limit for irrigation; assigning a linear relationship between a remotely disposed control lever (14) and vacuum provided to the handpiece (16) by the vacuum pump between zero and the vacuum limit; supplying vacuum to the handpiece (16) by actuating the control lever (14); and controlling the fluid flow to the handpiece (16) in response to the level of vacuum provided to the handpiece (16) so that as more vacuum is provided, less fluid flow than the fluid flow limit is provided to the handpiece (16).</p> |
