摘要：
A phacoemulsification system for operating a surgical handpiece having a handpiece； an irrigation fluid source for supplying irrigation fluid to the eye； an aspiration source coupled to the handpiece in order to aspirate the irrigation fluid from the eye through the handpiece； and a controller for controlling a vacuum in the handpiece, the controller comprising: a sensor for sensing the vacuum in the handpiece； an occlusion parameter, the occlusion parameter being a vacuum level corresponding to an occlusion of the handpiece or a flow rate corresponding to an occlusion of the handpiece； a maximum allowable vacuum level in the handpiece, the maximum allowable vacuum level having at least a first predetermined level； and a trigger value that is set based in part on the occlusion parameter.
