摘要：
A controller for a phacoemulsification system having a handpiece an irrigation fluid source configured to supply an irrigation fluid to the eye an aspiration source configured to aspirate the irrigation fluid from the eye through the handpiece and a controller comprising a duration timer configured to provide a duration of an occlusion, the controller configured to: sense a value of an occlusion indicating parameter corresponding to an occlusion of the handpiece measure a time since the occlusion of the handpiece and control the aspiration source to the handpiece based at least in part on the measured time since the occlusion. The occlusion indicating parameter may be a vacuum level, an irrigation flow rate, and/or an aspiration flow rate.
