Abstract

Purpose: To describe a new scleral fixation technique that comprises the transfixion of silicone foldable Intraocular Lens (IOL) with 7-0 polypropylene suture. Methods: Before surgery, the authors performed the transfixion of the IOL optic in four points with 7-0 polypropylene suture under a surgical microscope. Four sclerotomy sites were marked 2 mm from the limbus, and two scleral grooves were created in between. The IOL was introduced into the posterior chamber. The four ends of the needleless polypropylene sutures were externalized through the sclerotomies using micro graspers, tightened for optimum IOL centration, and tied. The exposed sutures were placed within the scleral grooves, and the knots were buried within the sclerotomies. This technique was performed uneventfully in 4 cases. Results: The silicone IOL was stable in all eyes 6 months after surgery, with no signs of IOL subluxation, dislocation, tilt, or suture-related complications, such as erosion or infection. Conclusion: The transfixion of the silicone foldable posterior chamber IOL for stable four-point scleral fixation using polypropylene suture provides excellent stability and prevents IOL tilt and decentration. Also, this technique provides an excellent alternative for surgeons who use silicone IOL.
