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.

1-27. (canceled)
A phacoemulsification system, comprising:
- a probe having a distal tip insertable into an eye, the tip energizable with ultrasonic energy and 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, and 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, transmit time coordinated command signals to energize the tip with the ultrasonic energy and switch between the pumping rates.
