    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: In certain embodiments, a system for assessing a floater in the eye of a patient includes a display device, input device, and computer. The display device displays a target and background. The background has an alignment point and alignment axis. The eye axis of the eye is substantially aligned with the alignment axis when the eye is fixating on the alignment point. The input device receives patient input from the patient. The computer provides target display input to the display device to yield the target moving according to a pattern for the eye to follow. The eye axis moves relative to the alignment axis as the eye follows the moving target. The computer records patient input indicating that the patient sees the floater. The computer calculates a severity score, which indicates the severity of the floater, according to the patient input and generates a report that describes the severity score.

    Abstract: A visualization system for dynamically visualizing an eye includes a laser module operable for outputting a primary laser beam along a beam axis, a beam splitter positioned in the beam axis and configured to direct a first beam portion along the beam axis and a second beam portion along a detection axis that is orthogonal to the beam axis. A microelectromechanical system (MEMS) scanner is arranged on the beam axis and configured, in response to the first beam portion, to output a scanning laser along a visualization path. An avalanche photodiode (APD) detector receives the second beam portion. A 4F correlator optical system has a spatial filter arranged along the visualization path. An optional optical flat may be disposed between the eye and the 4F correlator optical system to achieve stereo parallax.

    Abstract: The present disclosure relates generally to small-gauge instrumentation for surgical procedures, and more specifically, to vitreoretinal instruments for retinal repair and reattachment procedures, as well as associated methods of use. Certain embodiments of the present disclosure provide a curved or articulating probe configured to provide illumination, fluid aspiration, and endophotocoagulation. Accordingly, the probe enables aspiration of subretinal fluid that re-accumulates after initial drainage and during endophotocoagulation without the need to exchange surgical instruments or insert an additional instrument into the intraocular space. Furthermore, the combined functionalities of the probe enable a surgeon to simultaneously perform scleral depression with the surgeon's other hand while aspirating fluid and/or performing retinal endophotocoagulation.

    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.
