Publication number: 20240090762Abstract: 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.Type: ApplicationFiled: July 20, 2023Publication date: March 21, 2024Inventors: Charles Raymond Kalina, JR., Huong Khac Huynh, Douglas Daniel Crimaldi, Todd N.
