CPT® Code 66680

The procedure described by CPT® Code 66680 involves the surgical repair of the iris and ciliary body, particularly in cases of iridodialysis. Iridodialysis is a condition characterized by the separation of the iris root from the ciliary body or scleral spur, leading to the formation of an irregularly shaped pupil, often resembling a D-shape. This surgical intervention is necessary to restore the normal anatomy and function of the eye, as the separation can lead to visual disturbances and other complications. During the procedure, a miotic agent is administered to constrict the pupil, facilitating better access to the affected area. A corneal incision is then made to allow for the lysis of any synechiae, which are adhesions that may restrict the movement of the iris leaflets. The repair process involves meticulous approximation of the edges of the iris to ensure that the pupil is centrally located. If the injury involves the iris sphincter, this area is addressed first to maintain proper pupil function. The repair is completed by suturing the iris, with the needle being passed through a paracentesis tract in the anterior chamber and then through the iris itself, ensuring that both the proximal and distal leaflets of the iris are securely reattached. In cases of iridodialysis, the iris root is reattached to the ciliary body or scleral spur, and the sutures are tied and buried within the anterior chamber to promote healing and minimize complications.
