CPT® Code 66635

The procedure described by CPT® Code 66635 refers to an optical iridectomy, which is a surgical intervention involving the removal of a small, full-thickness section of the iris. This procedure is specifically categorized as a separate procedure and is performed with either a corneoscleral or corneal section. The primary objective of an optical iridectomy is to create an artificial pupil, which is achieved by excising a section of the iris located at the center of the eye. The process begins with the application of a local anesthetic to ensure patient comfort during the procedure. Following anesthesia, a precise incision is made either in the cornea or at the limbus of the sclera, allowing access to the iris. The surgeon utilizes specialized instruments, such as iris forceps or an iris hook, to grasp the edge of the pupil through the incision. Subsequently, iridectomy forceps are employed to draw the iris out through the incision, and iridectomy scissors are used to carefully snip off a small fragment of the iris. This excision is performed in a radial manner, ultimately forming an artificial pupil at the center of the eye, which can improve visual function for patients with specific ocular conditions.
