    Abstract: The systems and methods described herein provide improved techniques for OCT guided robotic ophthalmic procedures. A method includes receiving, during OCT scanning of an eye, position data of a plurality of galvanometer scanners from a plurality of absolute and incremental encoders coupled to the corresponding galvanometer scanners. The method further includes receiving scan data related to one or more tissues of the eye. The method further includes determining, a set of first positions of the one or more tissues of the eye in a first 3D coordinate system. The method further includes determining, based on the set of first positions and a mapping between the first and a second 3D coordinate systems, a position in the second 3D coordinate system for a surgical instrument coupled to a robotic device. The method includes causing the robotic device to move the surgical instrument to the position in the second 3D coordinate system.

    Abstract: Certain embodiments describe an endoilluminator having a tube that includes an interior compartment between a proximal end and a distal end of the tube, wherein the distal end of the tube is configured to be inserted into an eye. The endoilluminator also includes a handpiece coupled to a light source and the proximal end of the tube, wherein the endoilluminator is configured to filter an incident component of light transmitted by the light source and emit a polarized component of the transmitted light through the distal end of the tube.

    Abstract: A lens holder for an ophthalmic procedure is provided. The lens holder includes: a rim configured to hold a lens; and a flange coupled to the rim, the flange including a first surface configured to be positioned on an ocular surface of an eye and an opposing second surface. The flange includes one or more conjunctiva capture features extending from the first surface to the second surface of the flange, and the one or more conjunctiva capture features are configured to be latched on to one or more portions of conjunctiva of the eye.

    Abstract: Certain embodiments provide a method of performing ocular biometry. The method includes performing phacoemulsification to emulsify and remove an internal lens of an eye. The method further includes performing vitrectomy to remove vitreous from the eye. The method also includes placing a trial in a lens capsule of the eye. The method further includes performing biometry with a first biometry system to provide measurements including at least one of an axial length of the eye, a curvature of a cornea of the eye, and toric axis. The method also includes removing the trial from the lens capsule.

    Abstract: A system for treating a media opacity in a vitreous media of an eye includes a visualization module adapted to provide visualization data of a portion of the eye via one or more viewing beams. The system includes a laser module adapted to selectively generate a treatment beam directed towards the media opacity in order to disrupt the media opacity. The laser module and the visualization module have a shared aperture for guiding the treatment beam and the one or more viewing beams towards the eye, the shared aperture being centered about a central axis. A controller is configured to acquire one or more defining parameters of the media opacity and determine when the media opacity is with a predefined target zone of a real-time viewing window. The media opacity is treated with the treatment beam when the media opacity is within the predefined target zone.

    Abstract: The present disclosure relates to high dexterity manipulation systems for microsurgical procedures. The surgical system includes a master apparatus controllably coupled to a slave apparatus configured to couple to a patient's head with a dual tripod structure having two pluralities of linear actuator links pivotally supporting a surgical tool shaft. The motions of the linear actuator links are controlled to provide at least 6 degrees of freedom for the surgical tool shaft. The slave apparatus may further include a redundant axis rotatable tool shaft, thus enabling 7 degrees of freedom for a surgical tool. The surgical system includes sensors enabling forces of interaction between the slave apparatus and its environment to be reflected back to the master apparatus. Forces imparted onto the master apparatus by an operator can be fed forward to control the slave apparatus and scaled down to reduce the forces on target tissues.

    Abstract: In certain embodiments, a fluidic pump system includes a brushless slotless direct current (BSDC) motor mechanically coupled to a fluidic pump, and a motor controller communicably coupled to the BSDC motor. The BSDC motor is configured to drive the fluidic pump, and the motor controller is configured to generate command signals to drive the BSDC motor. The fluidic pump system further includes commutation circuitry coupled to the BSDC motor that is configured to provide digital sine-wave commutation of the BSDC motor and to provide an indication of movement of the BSDC motor to the motor controller.

    Abstract: The present disclosure provides a scene camera system including a scene camera that includes a lens and may detect light reflected off an exterior of an eye into the lens and send a signal corresponding to the detected light to a processor. The system further includes a main camera that may detect light reflected off an interior structure of the eye and send a signal corresponding to the detected light to the processor. The system also includes an image processing system including the processor that executes instructions to produce a scene camera digital image of the eye and a main camera digital image of the eye. The system further includes a multiple picture-in-picture display that displays the scene camera digital image of the eye and the main camera digital image of the eye concurrently.
