  • Patent number: 11826104
    Abstract: A gonioscopic attachment can attach to a gonioscope and can include atraumatic retention elements that are configured to engage an eye to retain the gonioscope relative to the eye. The gonioscopic attachment can be configured to position the gonioscope so that at least a portion of the concave distal surface of the gonioscopic optical element is spaced apart from the eye, and/or so that the curvature of the distal surface is angularly offset from the curvature of the eye. The gonioscope can include a fixation point configured to be visible to the subject when the gonioscope is positioned on the eye. In some embodiments, the retention elements can be incorporated directly into the gonioscope. A coupling mechanism can couple the gonioscope to a lid speculum.

  • Patent number: 11726318
    Abstract: Optical systems and methods for operation thereof are disclosed. A delimited zone is defined as a function of distance from the optical system based on a VAC limit, the delimited zone having at least one distance threshold. A virtual distance of a virtual depth plane from the optical system at which a virtual object is to be displayed is determined. It is determined whether the virtual distance is outside the delimited zone by comparing the virtual distance to the at least one distance threshold. A collimated pixel beam associated with the virtual object is generated by a projector of the optical system. The collimated pixel beam is modified to generate a modified pixel beam if the virtual distance is outside the delimited zone. Modifying the collimated pixel beam includes converging the collimated pixel beam and/or reducing a diameter of the collimated pixel beam.
