Abstract: The systems and methods described herein provide improved techniques for displaying imaging markers for verifying biometry. A method includes receiving an indication to initiate a first optical coherence tomography (OCT) scanning of an eye; initiating, based on the received indication, the first OCT scanning of the eye; generating, based on the first OCT scanning, a first OCT image of the eye; detecting, based on the first OCT image, a retinal pigment epithelium (RPE) and a fovea in the eye; based on the detecting, causing a first enhanced OCT image to be displayed to a user, the first enhanced OCT image displaying: a first virtual marker segmenting at least a portion of the detected RPE, and a second virtual marker, where the second virtual marker visually identifies a location of the detected fovea, and where the second virtual marker is a radial line through the location of the detected fovea.

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: A robotic system includes a base, a support column, and a selective-compliance-articulated robot arm (SCARA) connected to the base via the support column. The SCARA is configured with ophthalmic visualization-specific kinematics. The SCARA includes first, second, and third revolute joints. A first link is connected to the base via the first revolute joint. A second link is connected to the first link via the second revolute joint, has a distal end connected to the third revolute joint, and is configured as a four-bar mechanism. The second link is connectable to a microscope. A linear actuator is connected to the second link. In response to electronic control signals from an electronic control unit, the linear actuator controls vertical motion of the SCARA. None of the revolute joints of the SCARA functions in an anti-gravity mode.

Abstract: Certain aspects of the present disclosure provide a voice-controlled system for controlling devices and systems in a surgical setting. The voice-controlled system includes at least one microphone and at least one loudspeaker distributed within the surgical setting to receive and audibly respond to voice commands from operating staff. In certain aspects, the at least one microphone and at least one loudspeaker include a phased microphone array and a phased loudspeaker array that are coordinated and synchronized to perform active noise reduction, echo cancellation, and directional determination of sound sources. The voice-controlled system performs tasks, such as activation of surgical devices, based on verbal interactions with the operating staff through the at least one microphone and at least one loudspeaker. In certain aspects, the voice-controlled system is configured to recognize, decipher, and prioritize natural language commands from different operating staff, and further provides pre-programming of device settings and operating staff pre-sets.

Abstract: A visualization system includes a housing assembly having a head unit configured to be at least partially directed towards a target site. An optical coherence tomography (OCT) module and a stereoscopic camera are located in the housing assembly. A controller is in communication with the OCT module and the stereoscopic camera. The controller is adapted to acquire left OCT data and right OCT data of the target site, via the OCT module, and synchronously acquire left camera data and right camera data of the target site, via the stereoscopic camera. The controller is adapted to generate volume-rendered images, including: first and second OCT images based on the OCT data and first and second camera images based on the camera data. The first and second OCT images and the first and second camera images have matching parallax.

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, an ophthalmic system for visualizing an interior of an eye includes an illumination system and a visualization system. The illumination system illuminates the interior of the eye. The illumination system includes an annular illuminator that directs annular illumination, which has an illumination axis, towards the interior of the eye. The visualization system provides an image of the interior of the eye. The visualization system comprises visualization optical elements, which include an objective lens and oculars. The objective lens receives light reflected from the interior of the eye. The oculars, which have an ocular axis, transmit the reflected light to yield an image of the interior of the eye. In other embodiments, the illumination system comprises a multi-beam illuminator that directs multiple illumination beams towards the interior of the eye.
