Abstract
The inner eye of a surgical patient is illuminated by incorporating an optical fiber in a ring configuration imbedded into or attached to a contact lens. The viewing surface of the lens if planar to optimize the surgeon's view. The opposite surface of the lens is curved to conform to the patient's eye. A solution conduit irrigates the eye. The apparatus is easily positioned and easily directed. The apparatus also is sufficiently inexpensive to be disposable.
