Multi-functional eyelid speculum



Multi-functional eyelid speculum



Official Gazette of the United States Patent & Trademark Office Patents 1248(5), July 31



An eyelid speculum for separation of the eyelids with an automatic system for irrigation and aspiration. In one embodiment, the speculum is provided as a truncated cone-shaped main body with lid retractors extending out of it in the form of a ring, forming an angle appropriate to the curvature of the eye. Hollow rings are provided in the body of the cone with perforated channels for delivering irrigation fluid and for aspiration. Two syringes are provided, each connected by tubing to one of the hollow rings so as to either deliver irrigation or aspirate excess fluid. The irrigation and aspiration rates are controlled by an electronic processor which controls the rates of both activities independently. In another embodiment, the device is further provided with an illumination unit for trans-illumination via the sclera of the interior of the eyeball. The light which reaches the interior of the eyeball through the sclera is diff-use and homogeneous and thus comfortable for the surgeon to work with while not endangering the eye tissue. There is no need for the user to illuminate the eye with the harsh light of the microscope. In yet another embodiment, a second type of illumination unit is added which provides illumination of the anterior segment of the eye from an inclined angle so as produce soft and indirect lighting.
