Both the suture ends are pulled from either side (Figure 2D), and this leads to sliding of the helical loop inside the AC, thereby approx- imating the iris defect. The suture ends are cut leaving a 1 mm bud on either side (Figure 2E, F). Advantages and clinical application The need for a second pass is elimi- nated by the SFT technique, and it's not essential to take a second pass from the AC. This automatically translates into less intervention in the AC, thereby minimizing the iris manipulation and the secondary inflammation associated with it. SFT in endothelial keratoplasty (EK) In EK, a stable iris structure and support is essential as the iris con- tributes significantly to the stability of the anterior chamber, and it prevents the posterior migration of the graft during the EK procedure. It also prevents the escape of air into the vitreous cavity, thereby facilitat- ing graft adhesion by pushing the EK graft against the recipient bed. In the SFT procedure, the suture lies in line with the iris tissue, and as there is no knot, the rigid protrud- ing suture does not pose a risk for cases undergoing an EK procedure simultaneously. SFT for angle-closure glaucoma Performing an SFT helps to pull the iris away from the iridocorneal angle, thereby relieving the cases of appositional closure in angle-clo- sure glaucoma and plateau iris. It mechanically opens the angles and facilitates trabecular aqueous drain- age. Further, it could cut down the peripheral anterior synechiae by releasing the appositional closure and preventing these cases from going into chronic angle-closure glaucoma. The further role and application of SFT in glaucoma is currently being evaluated. The SFT technique provides a simple method of repair while mini- mizing manipulation and maintain- ing anterior chamber stability.
