Abstract
A surgical system for the treatment of ocular problems including a surgical cassette, a surgical console operatively coupled to the surgical cassette and further including a processor, a vacuum source positioned in-line with a vacuum regulator and a mass air flow controller, and a tank fluidly connected to the mass air flow controller, wherein the processor is configured to calculate an air flow set point in accordance with a received at least one user-defined fluid flow rate set point; and wherein the mass air flow controller modulates air flow from the tank to the vacuum source in accordance with the received the air flow set point to meet a user-defined fluid flow rate.
