ABSTRACT:
An improved ophthalmic fundus contact lens to observe and irradiate the interior of the eye. Internally the device consists of a ring of contiguous mirrors (12) with identical angulations arranged around a posterior concave lens (10). The outside surface of the instrument contains a wall (14) of exterior housing. A glass or transparent material (16) covers the anterior opening of the lens. The invention is particularly useful for faster and safer panretinal photocoagulation (PRP).
