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.

1-37. (canceled)
A system for removing material from within an eye, the system comprising:
- a probe having a distal tip insertable into the eye the tip and having an aspiration port;
- a console coupled with the port along an aspiration pathway, wherein the console comprises a processor and a pump system, and wherein the pump system comprises a first pump and a second pump for providing a first pump aspiration level and a second aspiration level that is higher than the first aspiration level;
- and wherein the processor is configured to cycle between the aspiration levels sufficiently for transient-induced effects of the aspiration level to help break-up the material for aspiration through the port.
