Abstract: A gonioscopy lens employs a plurality of mirror sets so that substantially the entire periphery of the anterior chamber of an eye can be viewed without rotating or moving the contact lens. Each mirror set comprises a first mirror position anterior to the eye on one side of the optical axis and a second mirror positioned posterior to the first mirror on the opposite side of the optical axis. Each set is oriented relative to each other so that the second mirror receives light rays from the peripheral portion of the anterior chamber, reflects those rays to the second mirror to the first mirror, and then reflects the light rays in a generally anterior direction so that they can be used by an ophthalmologist employing the lens. The image viewed by the ophthalmologist is upright and located over its actual position.

Abstract: An iridotomy and trabeculoplasty goniolaser lens has a contact lens element, a planar mirror offset from the optical axis of the contact lens element and first and second button lenses mounted on the anterior surface of the contact lens element. Magnification, curvature and location of the button lenses are chosen so as to provide the ability to simultaneously deliver laser energy to the iris of a patient's eye along a first optical path offset from the optical axis of the contact lens element and to view the trabecular meshwork around the region where the laser energy was applied. This ability eliminates the need for a plurality of contact lenses for delivering energy and viewing the eye and further eliminating the need for refocusing the microscope through which the surgeon views the eye.
