Abstract: The present disclosure provides a head tracking control system including at least one marker positioned on a head of a surgeon. The system further includes an infrared camera including at least two infrared sensors and that detects infrared light reflected off the at least one marker and sends a signal corresponding to the detected light to a processor, and that executes instructions on the processor to detect a movement of the at least one marker. The system also includes an intelligent tracking system that executes instructions on the processor to determine if the detected movement of the at least one marker corresponds to a defined head movement of the surgeon. The system further includes an ophthalmic surgical microscope including the processor. If the detected movement of the at least one marker corresponds to the defined head movement of the surgeon, the processor executes instructions to control the ophthalmic surgical microscope.

Abstract: The present disclosure relates to high dexterity robotic manipulation systems for ophthalmic microsurgical procedures. In certain embodiments, a robotic surgical system includes a master apparatus controllably coupled to a slave apparatus. The slave apparatus mounts to a patient's head and includes a dual tripod structure having two pluralities of linear actuator links pivotally supporting a surgical tool. The motions of the actuator links are controlled by direct drive actuators to provide at least 6-DOF for the surgical tool. A passive articulating arm having a SCARA mechanism and four-bar parallelogram mechanism attaches to the slave apparatus and counterbalances the weight thereof when mounted on a patient. The surgical system also includes sensors communicatively coupled to the slave apparatus and master apparatus to enable force feedback and force control. Accordingly, the robotic surgical system enhances the dexterity of an operator and enables performance of medical procedures more easily than by hand.

Abstract: An ophthalmic assembly includes a frame, flange, and light emitter. The frame supports an optical lens. A first end of the flange is connected to the frame. A second end of the flange rests on a pars plana region of the sclera of a patient's eye. The light emitter is connected to the flange proximate the second end to direct light into a vitreous cavity of the patient's eye. This occurs through the sclera at the pars plana region and uniformly illuminates the vitreous. A transscleral illumination system includes the ophthalmic assembly and a processor in communication with the light emitter. A setting of the light emitter may be controllable via the processor, e.g., in response to a user input signal.

Abstract: An apparatus for implant into an eye. The apparatus may comprise a receptacle configured to receive an optic; a flange circumscribing the receptacle, the flange configured to be disposed in the ciliary sulcus of the eye; and a fenestration through the flange, the fenestration configured to allow aqueous humor to pass anteriorly from the ciliary body to the trabecular meshwork of the eye. Some or all of the apparatus may have an oleophobic coating. For example, some embodiments of the flange may have an oleophobic coating. In some embodiments, the fenestration may be inferior to the receptacle. Additionally, or alternatively, the apparatus may further comprise at least two haptics coupled to the flange.

Abstract: Aspects of the present disclosure relate to an integrated contact lens apparatus for ophthalmoscopic examination comprising a lens portion, an upper speculum portion, and a lower speculum portion, and methods of use thereof. The integrated contact lens apparatus facilitates improved visualization of the peripheral retina, including the superior and inferior hemiretinas, via both manual examination and wide-angle cameras that may utilize contact lenses for viewing. The integrated contact lens apparatus further prevents or reduces corneal drying and patient discomfort during examination.

Abstract: Embodiments of the present disclosure generally relate to an ophthalmic surgical probe for extrusion. In certain embodiments, the probe includes a beveled probe tip that increases the area of vacuum generation at a target site without increasing probe gauge, thus facilitating improved tissue engagement. In certain embodiments, the probe further includes one or more texturized surfaces for improved “grabbing” and manipulation of target tissues, and/or one or more surfaces formed of polymeric materials to reduce unwanted damage and enhance the safety of use thereof.

Abstract: Certain embodiments provide a method of generating a color-corrected ophthalmic image. The method comprises obtaining an ophthalmic image of an eye with a nuclear sclerotic cataract or a tinted intraocular lens (“IOL”). The method further comprises determining color-shift information associated with the ophthalmic image based on at least one of user input and by processing the obtained image, the color-shift information indicative of the extent to which color in the obtained image is to be corrected to at least partially remedy the effect of the nuclear sclerotic cataract or the tinted IOL on the color of the obtained image. The method further comprises color-correcting the ophthalmic image based on the color-shift information. The method further comprises generating the color-corrected ophthalmic image based on the color-correcting.

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.
