    Abstract: A robotic imaging system 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 an optical assembly having at least one lens and defining a working span. The optical assembly has at least one focus motor adapted to move the at least one lens to selectively vary the working span. The robotic imaging system includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. The controller is adapted to selectively execute an orbital scanning mode causing the robotic arm to sweep an orbital trajectory at least partially circumferentially around the eye while maintaining focus.

    Abstract: A system for guiding an ophthalmic procedure is disclosed. The system includes a housing assembly with a head unit configured to be at least partially directed towards a target site in an eye. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second set of volumetric data, respectively. A controller is configured to register the first set and second set of volumetric data to create a third set of registered volumetric data. The third set and second set of registered volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a shared composite view of the target site. The controller is configured to extract structural features and/or enable visualization of the target site.

    Abstract: A retina viewing system and method of using the same includes an ophthalmic microscope, a disposable lens attachment, and an electronic control unit (ECU). The microscope has an optical head and a set of internal focusing lenses, the latter providing the microscope with a variable working distance or focal length. The disposable lens attachment includes a resilient body with a proximal end connected to the optical head and a distal end connected to a high-power/high-diopter distal lens. The ECU executes instructions for viewing a retina or other intraocular anatomy of a patient eye. Execution of the instructions causes the ECU to automatically adjust the variable working distance or focal length of the microscope when viewing an image of the retina through the distal lens.

    Abstract: A system, method, and apparatus for performing intraocular lens implantation using real-time surgical reference indicium are disclosed. An example method includes recording a patient specific pre-operative still image of an eye prior to cyclorotation of the eye when a patient lies down for surgery and generating at least one real-time multidimensional visualization of at least a portion of the eye for display. The method further includes using the patient specific pre-operative still image to at least produce at least one virtual surgical reference indicium including an ocular natural vertical axis of the eye and align the at least one virtual surgical reference indicium to the eye in conjunction with the real-time multidimensional visualization of at least a portion of the eye. The patient specific pre-operative still image is captured under a dilation condition selected from the group consisting of natural dilation, chemical dilation, and no dilation.

    Abstract: A method for identifying saline solution in an aspirated fluid mixture during vitrectomy or another vitreoretinal surgery includes estimating a fluid property value of the mixture via an electronic control unit (ECU). The mixture includes saline solution and either vitreous or silicone oil. The method includes identifying the saline solution as a primary constituent fluid of the fluid mixture, via the ECU, based on the fluid property value, and activating an indicator device in response to the primary constituent fluid being the saline solution. An automated system for identifying saline solution in the aspirated fluid mixture includes the indicator device and the ECU. A computer-readable medium includes instructions, executable by a processor to identify an aspirated fluid mixture during a vitreoretinal surgery, with execution of the instructions by the processor causing the processor to perform the method.
