Abstract: Certain aspects of the present disclosure provide a surgical system comprising a pump motor configured to couple to a pump for pumping material through a probe, wherein the probe is connected to the pump through a connector. The surgical system also comprises a control module configured to determine a real-time flow rate through the probe and adjust a current pump rate of the pump to achieve a target flow rate, wherein the current pump rate is adjusted based on the real-time flow rate.

Abstract: Systems and methods are disclosed for measuring fluid pressure in an ophthalmic surgical system. An example system comprises a fluid flow path and a pressure sensor system for measuring pressure in the fluid flow path. The pressure sensor system comprises a conductive, movable diaphragm having a first side and a second side, the first side of the diaphragm facing the fluid flow path, and an eddy current position sensor positioned on the second side of the diaphragm without contacting the diaphragm. The eddy current position sensor comprises a position sensor coil activatable by high frequency alternating current and signal conditioning electronics capable of sensing inductance or impedance or resonant frequency variation in the position sensor coil as a gap between the diaphragm and the position sensor coil changes and of translating that variation into a displacement signal correlated to fluid pressure. A method of measuring fluid pressure may be performed using one or more of the systems described herein.

Abstract: According to certain embodiments, a surgical cassette for an ophthalmic surgical system comprises an irrigation conduit that is in fluid communication with a handpiece and carries fluid toward a surgical site. An aspiration conduit is in fluid communication with the handpiece and carries fluid away from the surgical site. An aspiration pump creates a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit towards a drain reservoir. A reservoir couples with a pressure-vacuum source to manage the reservoir pressure. A valve is in fluid communication with the aspiration conduit and the reservoir, and provides one or more channels between the aspiration conduit and the reservoir. Each sensor detects a pressure associated with the surgical site. A computer controls the valve in response to the pressure detected by the one or more pressure sensors to mitigate a pressure or volume change.

Abstract: A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on an estimated flow value modified by a compensation factor.

Abstract: Systems and methods for monitoring for an occlusion in an aspiration line during an ophthalmic surgical procedure. An ophthalmic surgical system may include a first aspiration pump located in a handpiece, a second aspiration pump located away from the handpiece such as in a console, and a pressure sensor located between the first aspiration pump and the second aspiration pump. The pressure sensor is adapted to monitor for an occlusion in the aspiration line upstream of the first aspiration pump. The second aspiration pump may be operated at the same flow rate as the first aspiration pump and/or to maintain a constant pressure between the second aspiration pump and the first aspiration pump. Systems and methods as disclosed allow for a handpiece pump located close to the working tip while providing reliable occlusion detection with a pressure sensor located away from the handpiece.
