  • Patent number: 11019997
    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. The gonioscope can include a light pipe, which can be configured to directly light into the eye.

  • Publication number: 20190321220
    Abstract: Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with a suprachoroidal space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space or other portion of the uveoscleral outflow path. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery through a preformed corneal incision, or independently with the inserter configured to make a corneal incision. The implant can be preloaded with or within the inserter to advantageously provide a sterile, easy-to-use package for use by an operator.
