Abstract
Purpose: We report the longest follow-up to our knowledge of stable scleral fixation of a posterior chamber intraocular lens (PC IOL) with 10-0 polypropylene sutures. Methods: A retrospective review is presented of a case with more than 30 years’ follow-up after performing sutured scleral fixation with 10-0 polypropylene suture using 2 sutures tied together under a scleral flap. One suture was a cow-hitch looped around the haptic, and the other suture was passed through the sclera to create the scleral fixation. Results: The scleral fixation with 10-0 polypropylene suture knots for both haptics of the PC IOL allowed central optic positioning with excellent vision for more than 30 years without suture breakage. Conclusions: Polypropylene sutures for scleral fixation of PC IOLs remained stable for more than 30 years with central positioning of the PC IOL, without exposure of the fixation suture knots through the conjunctiva, and without suture breakage.
