1. A system for removing material from within an eye, the system comprising:
- a probe having a distal tip insertable into the eye, wherein the tip comprises an aspiration port and an irrigation port;
a console coupled with the aspiration port along an aspiration pathway, wherein the console comprises a processor and a pump system for providing a first pump rate and a second pump rate higher than the first pump rate, and an irrigation system for providing a variable irrigation rate,wherein the processor is configured to;
automatically switch from the first pump rate to the second pump rate,vary the irrigation rate according to the pump rates,determine whether the second pump rate exceeds a maximum irrigation rate of the irrigation system, anddecrease an aspiration rate to the aspiration port of the probe to match the irrigation rate of the irrigation system responsive to determining that the second pump rate exceeds the maximum irrigation rate of the irrigation system.

Abstract
Methods and apparatuses for automatically switching different aspiration levels to an ocular probe are disclosed herein. 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. Control feed back of the pumps may be varied according to set thresholds.
