The flanged double-needle technique has been described by Yamane and colleagues for secured fixation of an IOL transsclerally. Threading of the trailing haptic and its externalization are often met with surgical challenges, and various modifications have been described for atraumatic and easy externalization of the IOL haptics. The handshake technique has been described for glued IOL fixation to facilitate trailing haptic externalization. The riveting technique for iridodialysis repair has been described by Kusaka and colleagues, wherein the 6-0-Prolene suture is passed through the peripheral iris tissue to the scleral wall groove and the flanged and riveted ends of the suture hold the peripheral iris tissue in place. The riveted ends are achieved by heating the suture end with a low-temp cautery and then pressing the flanged bulb to make it more flat and wide.
