This video demonstrates modified techniques to repair the iris and to perform phaco in challenging cases. Manish Mahendra, MD, shares a "single-pass four-throw" pupilloplasty technique in which a single pass of a 9-0 prolene suture on a long arm needle is passed through the iris tissue, followed by creation of a loop with four throws that slides inside the eye. This creates a helical configuration that prevents the suture from opening up, thereby creating a relatively round pupil. For iridodialysis repair, the "hangback technique" is employed whereby 9-0 prolene sutures are used to bring the peripheral iris under the limbus. In another case, the "modified sewing machine" technique is used in which a scleral tunnel is made parallel to the damaged portions of the iris and a 9-0 prolene suture threaded through a 26-gauge needle and passed through the peripheral iris to create suture loops.
