Hybrid Yamane-sewing technique for post-traumatic iridodialysis and intraocular lens relocation: a novel approach

BACKGROUND: Post-traumatic iridodialysis with intraocular lens (IOL) subluxation presents a surgical challenge requiring simultaneous iris repair and IOL stabilization. This case report introduces the Hybrid Yamane-Sewing Technique, combining Yamane scleral fixation for IOL repositioning with the sewing machine technique (SMT) for iridodialysis repair. This minimally invasive approach aims to optimize outcomes while reducing surgical complexity and recovery time.METHODS: A 65-year-old male with blunt ocular trauma presented with severe iridodialysis (9 to 1 o’clock) and inferonasal IOL subluxation. A 25G pars plana vitrectomy was performed to clear vitreous adhesions, followed by sutureless Yamane scleral fixation for IOL stabilization. The SMT was used for iridodialysis repair, ensuring uniform tension and natural iris repositioning. The procedure was completed without corneal incisions to minimize postoperative astigmatism and inflammation.RESULTS: The patient experienced significant visual improvement with stable IOL fixation. Best-corrected visual acuity (BCVA)improved from hand motion to +0.3 logMAR (day 1) and +0.1 logMAR (12 months). The iris remained anatomically aligned with good functional and cosmetic outcomes. No significant complications, including increased intraocular pressure or cystoid macular edema, were observed.CONCLUSIONS: The Hybrid Yamane-Sewing Technique provides a safe, effective, and minimally invasive solution for simultaneous IOL stabilization and iridodialysis repair. By integrating sutureless fixation with precise iris reconstruction, it minimizes surgical trauma, reduces operative time, and enhances visual rehabilitation. Its reproducibility and cost-effectiveness make it a promising alternative for anterior segment trauma and complex IOL dislocations. Further studies are needed to validate its broader applications.
