Purpose: To develop a new, sutureless intrascleral intraocular lens (IOL) fixation technique based on the Yamane double-needle and Canabrava 4-flanged techniques. Methods: The Fusion-Flanged technique involves using a 7-0 polypropylene suture loop threaded through the eyelets of the IOL. Afterward, both ends of the suture are passed outside the eye through a 27-gauge needle. This technique creates a single flange by joining the 2 suture ends through handheld cautery, and this flange is then embedded into the scleral tunnel to securely fix the IOL in place. Results: This technique was performed on a total of 7 aphakic patients. Four of them had encountered complications following manual small incision cataract surgery, while the remaining 3 experienced complications after phacoemulsification. The results indicated a significant improvement in visual acuity, with mean preoperative and postoperative corrected distance visual acuities of 0.77 ± 0.11 and 0.27 ± 0.08 (logarithm of the minimum angle of resolution logMAR units), respectively. Conclusions: The Fusion-Flanged intrascleral IOL fixation technique offers improvements in simplicity, safety, and the overall efficiency when compared to existing sutureless intrascleral fixation techniques. Notably, this technique is versatile and can be applied to both non-foldable and foldable IOLs.
