Abstract: An ophthalmic surgical system includes a robotic arm disposed above a patient's eye. A positioning camera is disposed on the robotic arm and positioned to visualize the patient's eye. A processor is electrically coupled to the positioning camera. The processor is configured to receive an indication of a position of the robotic arm relative to a fixed datum, determine a focal length between the positioning camera and the patient's eye, compare the focal length to the position of the robotic arm, and determine a patient eye level relative to the fixed datum.

Abstract: Ophthalmic surgical systems and methods for displaying graphical user interfaces in ophthalmic surgical systems are disclosed. An example ophthalmic surgical system has alternative setup conditions, and a host computer is configured to detect the setup condition and to display on a display screen a graphical user interface corresponding to the detected setup condition. The alternative setup conditions may be based upon a configuration of an ophthalmic surgical console and/or based upon which type of fluidics cassette is installed on the ophthalmic surgical console. In some embodiments, the host computer is configured to display on the display screen a graphical user interface that graphically indicates the instrument ports that are available and/or that are not available for instrument connections in the detected setup condition.

Abstract: A surgical system for wirelessly charging a foot controller is described. The surgical system includes a surgical console. The surgical system also includes a foot controller wirelessly coupled to the surgical console and adapted to control one or more operations of the surgical console. The surgical system further includes a charging apparatus coupled to the surgical console and adapted to wirelessly charge the foot controller.

Abstract: The present disclosure generally relates to fluid control valves for delivering and/or aspirating fluid during ophthalmic surgeries and procedures. In one embodiment, a valve assembly includes a first portion configured to fluidly couple with a gas supply line and a second portion configured to fluidly couple with a liquid supply line and an infusion line. The first portion and the second portion are partitioned or separated from each other by a filter having a hydrophobic membrane configured to prevent the flow of liquids therethrough while allowing the free flow of gas. Accordingly, an infusion liquid may be flown through the second portion while gases may be simultaneously aspirated through the first portion, without any liquids travelling into the gas supply line. The gas supply line may thus be utilized to vent or purge gases from the infusion line before or during performance of surgical procedures.

Abstract: A surgical console has a receptacle for receiving a surgical fluidics cassette. The receptacle has a light source that transmits light to light pipes in the surgical fluidics cassette. The light pipes transmit light to a light transmissive optical interface surrounded by an opaque frame in the surgical fluidics cassette. The opaque frame is located at a fluid level detection system in the cassette. The system illuminates fluidic connectors on the surgical fluidics cassette without interfering with the fluid level detection system of a surgical console.

Abstract: The present disclosure provides a capsulotomy device having a unique insertion sleeve configuration comprising beveling and two notches at the distal end of the insertion sleeve. The unique configuration assures that the motion the capsulotomy loop comprising the heating element goes through during deployment from and retraction into the insertion sleeve is minimized and predictable.

Abstract: In various embodiments, a device for delivering pressurized irrigation may include a squeeze plate and a pressure sensor module. The squeeze plate may move relative to the pressure sensor module to apply pressure to a flexible container (e.g., a bag of irrigation fluid) between the squeeze plate and the pressure sensor module. The pressure sensor module may include a pressure sensor to measure a force exerted on the pressure sensor module by the flexible container as pressure is applied to the flexible container from the squeeze plate. In some embodiments, the pressure sensor module may include a bag contact plate and the pressure sensor may measure a force exerted on the bag contact plate by the flexible container located between the bag contact plate and the squeeze plate. In some embodiments, the pressure sensor may sense a pressure associated with the flexible container without an intervening bag contact plate.
