    Abstract: A stereoscopic imaging platform includes a stereoscopic camera configured to record left and right images of a target site. A robotic arm is operatively connected to the stereoscopic camera, the robotic arm being adapted to selectively move the stereoscopic camera relative to the target. The stereoscopic camera includes a lens assembly having at least one lens and defining a working distance. The lens assembly has at least one focus motor adapted to move the at least one lens to selectively vary the working distance. A controller is adapted to selectively execute one or more automatic focusing modes for the stereoscopic camera. The automatic focusing modes include a continuous autofocus mode adapted to maintain a focus of the at least one stereoscopic image while the robotic arm is moving the stereoscopic camera and the target site is moving along at least an axial direction.

    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 via two or more through channels. 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 flow 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: Certain embodiments disclosed herein provide a surgical cassette including a housing, one or more retaining rings coupled to the housing, and one or more valve assemblies coupled to the housing by the one or more retaining rings. The one or more valve assemblies configured to control fluid communication between one or more channels within the housing. Each valve assembly includes a valve body having a first end, a second end, a cylindrical surface connecting the first end and second end, and a valve elastomer. The valve elastomer includes a first side configured to couple the valve elastomer to the second end of the valve body and a second side having a recessed surface configured to engage with the housing to form a seal with a base of the housing and reduce mechanical stress across the valve elastomer during rotation of the valve assembly.

    Abstract: Techniques for controlling data access using machine learning are provided. In one aspect, first, second, and third training data sets are generated from a set of historical access records and a set of historical data records, where the access records correspond to requests for data and comprise information identifying whether the request satisfies one or more data access rules, and the data records correspond to data elements and comprise information identifying whether the data element satisfies the one or more data access rules. One or more machine learning models are trained based on the first, second, and third training data sets to generate an output identifying whether requests for data should be granted.

    Abstract: Certain embodiments provide a vitrectomy probe including a housing, an actuator disposed inside the housing, a cutter coupled to the actuator and extending from the housing and an air turbine disposed inside the housing. The air turbine includes a rotor and a plurality of turbine blades coupled to the rotor. The vitrectomy probe includes a valve body interfacing with the rotor. During rotation of the air turbine, air is selectively routed to and from the actuator according to a rotational position of the rotor in relation to the valve body, thereby reciprocating the cutter.

    Abstract: A control system for an ultrasonic hand piece is provided. The control system includes an irrigation pressure sensor configured to measure a pressure of an irrigation fluid, an ultrasonic power source configured to provide power to an ultrasonic transducer, and a controller. The controller is configured to receive a selection of an ultrasonic power modality, generate a control signal based on the selected ultrasonic power modality, provide the control signal to the ultrasonic power source, determine an irrigation flow rate from a measured irrigation pressure provided by the irrigation pressure sensor, calculate a thermal index value based on the irrigation flow rate and the selected ultrasonic power modality, and, in response to the thermal index value reaching a threshold value, adjust the control signal based on the thermal index value. The ultrasonic power modality is one of a two dimensional power modality and a three dimensional power modality.
