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.

A Phacoemulsification surgical system provides a live video feed from a camera that is attached to a surgical microscope. The live video feed is shown as part of a graphical user interface (GUI) of phacoemulsification surgical console either in a picture in picture or a full-screen format. The video feed is either static or displayed on-demand as needed during a surgical procedure. The displaying of a live video feed directly on the phacoemulsification surgical console allows for surgical assistants to interact with the live video feed and phacoemulsification surgical system parameters and/or GUI controls without having to refocus on an external object between near and far distances.

Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.
