Abstract
Methods and systems for automatically pulsing different aspiration levels to an ocular probe are disclosed. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level, and applied to the probe in a pulsed manner.

31. A method for applying aspiration to a probe device, comprising:
-
applying a low flow-rate aspiration from a first pump to an aspiration port of a phacoemulsification device; detecting that the aspiration port is sufficiently occluded; and cycling a high flow-rate aspiration with a high-flow rate reflux from the first pump to the aspiration port. - View Dependent Claims (32, 33, 34, 35)

36. A method for removing material from an eye, comprising:
-
applying a first aspiration level to an aspiration port of a probe within an eye; applying a second aspiration level higher than the first aspiration level to the port; and cycling between the aspiration levels sufficiently for transient-induced effects of the aspiration level to help break-up the material for aspiration through the port. - View Dependent Claims (37)
