Abstract: The present disclosure provides ophthalmic viewing systems for visualizing structures on and in an eye of a medical patient. Certain embodiments provide an ophthalmic viewing system including an ophthalmic microscope, a gonioscopy device configured to relay images of an interior periphery of a patient's eye to the ophthalmic microscope, and a robotic arm configured to hold the gonioscopy device in a position in relation to the ophthalmic microscope and the patient's eye to relay the images of the interior periphery of the patient's eye to the ophthalmic microscope for viewing by a user.

Abstract: A system includes an actuator, one or more items of diagnostic equipment configured to perform ophthalmic measurement, and one or more items of treatment equipment configured to facilitate performance of an ophthalmic treatment with respect to an eye of a patient. A controller is coupled to the actuator and is configured to cause the actuator to transfer the one or more items of diagnostic equipment and the one or more items of treatment equipment into and out of a region in front of an eye of the patient. The ophthalmic treatment may be a LASIK or SMILE treatment using refractive error and/or eye geometry measured using the diagnostic equipment.

Abstract: A system includes a display device and an actuated structure mounted to the display device and configured to move the display device in three-dimensional space. The system includes an imaging device configured to capture images of a patient's eye during an ophthalmic surgery and display the images on the display device. A controller is configured to activate the actuated structure to maintain visibility of the display device to a surgeon performing the ophthalmic surgery. The display may be positioned based on a surgeon profile and/or a treatment plan. Whether the display is visible may be determined based on images from a camera mounted to the imaging device, the display device, or elsewhere. Whether the display is visible may be determined based on kinematic data for the actuated structure and/or a support for the imaging device.

Abstract: A system and method for assisting a surgeon performing an ophthalmic procedure on an eye of a patient, the system including a lubrication assembly. The lubrication assembly may be disposed on a proximal end of a robotic arm, a proximal end of a surgical microscope, or a proximal end of a mobile stand or frame. Dispersal of lubricant from the lubrication assembly may be upon receipt of a direct input from a surgeon, according to a predetermined schedule, or according to an image processing protocol. The lubrication assembly may be moved into position over the eye of the patient manually by the surgeon or through the indirect command of a motion controller which is operable to move the robotic arm or the surgical microscope so as to extend the lubrication assembly into a desired position.

Abstract: A system for assisting a surgeon performing intraocular surgery on an eye of a medical patient includes a robotic arm and a tool assembly at a working end of the robotic arm. The tool assembly can include a proximal end mounted to the robotic arm's working end, a distal end, and a narrow elongate support member extending between the tool assembly's proximal and distal ends. A motion controller is operable to move the robotic arm to extend the distal end and at least a portion of the support member through an incision site in a surface of the patient's eye, thereby to locate a visualization element at the distal end of the tool member at a position inside the patient's eye.

Abstract: Disclosed herein are systems and methods for adjusting an intraocular lens (IOL) with optical coherence tomography (OCT) guidance. The IOL can comprise an optic portion and a plurality of haptics. In one embodiment, a method can comprise directing a laser beam generated by a laser system at a composite material making up part of the IOL. At least part of the composite material can expand in volume in response to the laser beam directed at the composite material. The method can also comprise measuring a volume change of the composite material or a change in at least part of the IOL by analyzing OCT images produced by an OCT imaging apparatus and determining a change in a base power of the IOL based on the measurements.
