Modified Yamane Technique: A Case Series

Journal Title: Journal of Ophthalmology and Advance Research - Year 2025, Vol 6, Issue 1

Abstract

Objective: Yamane, et al., introduced a sutureless Scleral Fixation of Intraocular Lens (SFIOL) technique using 30-gauge thin-wall needles to externalize both haptics of a three-piece Intraocular Lens (IOL) through transconjunctival sclerotomies. This technique has some limitations and challenges such as the creation of symmetrical sclerotomies and the externalization of haptics. Therefore, we propose a modified approach employing trocars and forceps as an alternative method to externalize the IOL haptics. Methods: Six eyes of 6 patients underwent this modified technique consists of using two 27-gauce trocars to create symmetrical angled scleral tunnels and a three-piece IOL (MA50BM, Alcon Inc., Fort Worth, USA). A pair of 27-gauge microforceps is also used to externalize the IOL haptics instead of needles. Best Corrected Visual Acuity (BCVA) and occurrence of complications were the main outcomes measured. Results: The mean BCVA was 1.18 ± 0.48 logMAR (range 0.7-2) and improved to 0.096 ± 0.123 logMAR (range 0-0.3) at their most recent postoperative consultation. There were no complications. Using forceps to directly grip and externalize the haptics not only avoids the complexities of threading the haptic through a thin needle, but also reduces surgical time. The increased robustness and larger optic diameter of the MA50BM IOL reduces the effects of a mild decentration compared to the CT Lucia 602 three-piece IOL (Carl Zeiss Meditec, Jena, Germany) that is commonly employed in the standard Yamane technique. Conclusion: Our procedure achieved satisfactory results comparable to outcomes described by Yamane, et al., without occurrence of any complications.
