摘要
The present application relates to a phacoemulsification system, comprising: a surgical handpiece; an irrigation fluid source adapted to supply irrigation fluid to the eye; an aspiration source adapted to aspirate the irrigation fluid from the eye through the handpiece; and a control unit comprising a flow rate sensor, wherein the flow rate sensor is configured to sense a flow rate corresponding to an occlusion of the handpiece; wherein the control unit is configured to control a vacuum based in part on the flow rate corresponding to the occlusion; and wherein the control unit is configured to control the vacuum by lowering the maximum level of vacuum level allowed during a surgical procedure.
