Abstract
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.
