Abstract

To describe a new scleral fixation technique potentially usable for every acrylic foldable intraocular lens (IOL) available in the market, regardless of whether it is a three-piece, single-piece, or haptic shape. Before surgery, the authors performed the transfixion of the IOL optic in four points with the polytetrafluoroethylene 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 polytetrafluoroethylene sutures were externalized through the sclerotomies, 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 7 cases. The foldable 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. The transfixion of the foldable posterior chamber IOL for stable four-point scleral fixation using a polytetrafluoroethylene suture provides excellent stability and prevents IOL tilt and decentration. This technique can immensely benefit patients requiring secondary foldable posterior chamber IOL implantation in the absence of capsular support. [J Refract Surg. 2021;37(3):180-185.).
