ABSTRACT:
A contact lens for use in connection with transscleral cyclophotocoagulation. The lens has a planar entry surface and a frustoconically-shaped exit surface that contacts the sclera surrounding the cornea. The central portion of the lens is opaque to prevent stray laser light from entering the optical portion of the eye during laser application.
