Suction-assisted two-piece cased wide-angle contact lens for vitrectomy.
The conventional two-piece cased wide-angle contact lens is modified to enhance its contact system by four quadrant plate extensions. A metal housing attached to the side of the plate has an opening at the inferior surface. A suction device is attached to the housing. Suction created by the device holds the contact lens on the cornea. This lens reduces the need for a skilled assistant to stabilize the contact lens. It provides a stable, well-centered view of the peripheral fundus during vitreous surgery.
