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.

1-13. (canceled)
A system for removing tissue from within an eye, comprising:
- a probe having a distal tip insertable into the eye the tip having an aspiration port;
- and
- a console coupled with the port along an aspiration pathway, wherein the console comprises a processor and a pump system, wherein the pump system comprises a first pump and a second pump for providing a first pump rate and a second pump rate that is higher than the first pump rate;
- and wherein the processor is configured to, during pumping of aspiration flow along the aspiration pathway at the first pump rate and in response to insufficient occlusion of the aspiration pathway, generate a command signal so as to induce pumping of the aspiration flow along the aspiration pathway at the second pump rate.
