    摘要： The present application relates to 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 (48; 57) and a second pump (48; 57) adapted to provide a first pump rate and a second pump rate. The system is characterized in that the second pump is capable of a higher pump rate than the first pump, wherein the second pump rate is higher than the first pump rate; and in that, according to a first aspect, 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, or in that, according to a second aspect, 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.

    摘要： The present application relates to a system for removing material from within an eye, the system comprising: a probe having a distal tip insertable into the eye 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 (48; 57) and a second pump (48; 57) adapted to provide a first pump aspiration level and a second aspiration level. The system is characterized in that the second pump is capable of a higher pump rate than the first pump, wherein the second aspiration level is higher than the first aspiration level; and in that 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.
