  • Publication number: 20240090762
    Abstract: Gonioscope devices are disclosed herein that are configured to enable a medical professional to view structure inside the eye that is ordinarily hidden from normal view. The gonioscope can be an integrally molded single piece that includes both a handle and a gonioscopic optical element. The proximal surface can have a viewing area and a light diffusing area. A recess can provide access to a wound site on the eye while the gonioscope is used for viewing. The handle can be configured to encourage proper alignment of the gonioscope with the eye. The gonioscope can provide an optical fixation point for the subject to focus on to facilitate proper alignment of the eye. The gonioscope can have one or more retention elements configured to engage the tissue of the eye around the contact surface to stabilize the gonioscope. The gonioscope can couple to a lid speculum.

  • Publication number: 20220330979
    Abstract: Systems and methods for delivering multiple ocular implants to reduce intraocular pressure are disclosed. The ocular implants can be implanted at multiple sites within a single human eye without requiring removal of the delivery apparatus from the eye. A system for delivering multiple ocular implants can include a plurality of implants, an external housing, and an introducer assembly. The external housing can provide access to an implant singulation actuator and an implant delivery actuator. The introducer assembly can comprise an auto-retracting introducer portion. The delivery apparatus can include an infinite activation mechanism/portion and/or a manual singulation mechanism/portion.
