Abstract
An illuminated intraocular surgical instrument having a grip and a tubular member supported by the grip and extending outwardly from its first end. A surgical tool has a shaft extending from within the tubular member outwardly from the distal end of the member to a free end. The shaft of the tool extends generally along the longitudinal axis of the tubular member as it exits the member through its open distal end. A plurality of light conducting fibers extending through the tubular member have terminal ends located generally at the distal end of the member. The light fibers are arranged at the open distal end of the tubular member generally around the shaft of the tool within the tubular member to illuminate the portion of the surgical tool disposed outwardly of the distal end of the tubular member and the area of operation, and to inhibit the casting of shadows by the surgical tool in the area of operation.
