Application of a system parameter as a method and mechanism for controlling eye chamber stability

摘要

A method for operating a surgical system including placing a handpiece in an operative relationship with an eye for a surgical procedure. The method also comprises supplying irrigation fluid from an irrigation fluid source to the eye and applying vacuum from an aspiration source to the handpiece in order to aspirate the irrigation fluid from the eye through the handpiece. The method further comprises sensing a value of an occlusion indicating parameter corresponding to an occlusion of the handpiece and, from the sensing of the value, determining a duration of occlusion. The method additionally comprises controlling a controlled system parameter based at least in part on the duration of occlusion.
