    Reverse 4-Throw Pupilloplasty Technique

    Cornea/External Disease

    In this video, Rhea Narang and Dr. Priya Narang demonstrate a reverse 4-throw pupilloplasty surgical technique. This method takes 4 throws to achieve a suture knot (similar to a single pass 4-throw pupilloplasty procedure), but the suture knots are formed on the posterior iris surface rather than on the anterior side. This technique for burying sutures can be beneficial for certain kinds of cases such as endothelial keratoplasty, in which the presence of a suture knot or tail in the anterior chamber could damage the endothelial graft during unfolding or graft insertion.
