Automatically switching different aspiration levels and/or pumps to an ocular probe

A system for removing material from within an eye, the system comprising:

• a probe having a distal tip insertable into the eye, wherein the distal tip comprises an aspiration 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 via a first pump and a second pump rate via a second pump that is higher than the first pump rate;
• and
• wherein the processor is configured to automatically switch from the first pump rate to the second pump rate, to begin a ramp-up of the second pump before a ramp-down of the first pump such that a flow rate while providing the first pump rate is matched to a flow rate when switching from the first pump rate to the second pump rate, to control aspiration through the probe by tracking a vacuum level up to a threshold, and to control aspiration through the probe by tracking a flow rate through the probe when the threshold has been passed.
