Abstract: Active noise cancellation is employed to address unwanted acoustical noise generated by various equipment associated with an ophthalmic surgical system. Active noise cancellation may be used within a chassis of the ophthalmic surgical system, within an air compressor used with the ophthalmic surgical system, and within a reciprocating surgical probe used with the ophthalmic surgical system.

Abstract: A method and system provide a surgical system including a cassette, a console and an interferometric pressure sensing system coupled with the console. The cassette is for exchanging material with a patient and includes a wall and a reflector. The wall undergoes a deflection in response to a nonambient internal cassette pressure. The console is coupled with the cassette. The interferometric pressure sensing system is coupled with the console. The interferometric pressure sensing system includes a light source and a detector. The light source provides a first portion of light that is reflected off of the reflector and a second portion of light that bypasses the reflector. The first portion and the second portion of light are recombined to form an interference pattern. The deflection corresponds to a shift in the interference pattern detectable by the detector.

Abstract: Disclosed is a surgical footswitch, comprising a base, a pedal mounted to the base, and a variable air capacitor mechanically coupled to the pedal, such that movement of the pedal is operative to vary the capacitance of the variable air capacitor. The footswitch further comprises a capacitance-sensing controller circuit electrically connected to the variable air capacitor and configured to measure a capacitance of the variable air capacitor and to produce a control signal based on the measured capacitance, such that the control signal reflects a position of the pedal or a change in the position of the pedal, and a wireless interface electrically connected to the capacitance-sensing controller circuit and configured to wirelessly relay the control signal to a surgical console.

Abstract: An ophthalmic surgical system comprises: a camera optically coupled to a surgical microscope; a virtual reality (VR) headset worn by a surgeon; and a VR data processing unit configured to communicate with the surgical microscope, the VR headset, and an ophthalmic surgical apparatus, wherein the VR data processing unit is configured to: project a real time video screen of video received from the camera into the VR headset; project a patient information screen into the VR headset to provide the patient information directly to the surgeon during ophthalmic surgery; project a surgical apparatus information screen into the VR headset; project a surgical apparatus input control screen into the VR headset to provide the surgeon with direct control over the surgical apparatus; and control which ones of the screens are visible in the VR headset based inputs indicating head movements of the surgeon as detected by the VR headset.

Abstract: Embodiments of the present invention may allow each of the surgical steps of a surgical procedure to be defined and associated with a function of the surgical console using a GUI. The defined surgical procedure can then be saved and later invoked by a user of the surgical console to conduct the surgical procedure. When the saved surgical procedure is invoked representations of the defined surgical steps are displayed to the user using a GUI so the user can conduct the surgical procedure by navigating through the representations of the surgical steps such that when a representation of a surgical step is selected the surgical console is configured according to the functionality associated with that surgical step.

Abstract: Embodiments of the present invention provide a system and method for allowing a user to modify a surgical procedure. An embodiment of the method of the present invention can include: providing a GUI on a touch screen of a surgical console, said GUI comprising a representation of the surgical procedure and representations of one or more surgical steps, wherein the GUI allows a user to modify the representation of the surgical procedure by dragging and dropping representations of surgical steps using the touch screen; detecting that the representation of the surgical procedure has been modified; and modifying the surgical procedure to correspond to the modified representation of the surgical procedure.

Abstract: Embodiments of the present invention provide a system and method useful in setting up a complex ophthalmic surgical instrumentation and consumables associated therewith. One embodiment is directed to a surgical system capable of displaying a video showing setup instructions corresponding to a consumable or a consumable pack. Each pack may contain one or more consumables. Once a consumable is scanned, selected, or otherwise identified, the surgical system may operate to query a database to obtain Directions For Use (DFU) and other data associated with the consumable, update pack settings accordingly, and provide setup instructions in various modes, including the Wizard. The Wizard provides setup instructions (e.g., visual, audio, text, etc.) one step at a time and displays the next step in a pre-defined setup sequence only when the preceding step has been correctly and successfully completed.

The microsurgical system includes a computer, a foot controller operatively coupled to the computer, and a touch screen display operatively coupled to the computer. The foot controller has a plurality of switches. Each of the switches is for controlling a surgical function of the microsurgical system and for actuation by a user's foot. The touch screen display has the ability to display a graphic representation of the foot controller including the plurality of switches, and to display a list of surgical functions so that the list is associated with the graphical representation of one of the plurality of switches. By touching one of the surgical functions in the list, a user can exchange the surgical functions associated with any two of the plurality of switches on the foot controller.
