Introduction: Cataract surgery technologies continue to manage complications. Current surgical methods for secondary Intra Ocular Lens (IOL) include Anterior Chamber IOL, Iris Claw IOL, and sutured and sutureless techniques of Scleral Fixation IOL (SFIOL). The Yamane technique of SFIOL is a novel, relatively safe, and easy method of sutureless SFIOL. This study aims to describe and analyze the surgical outcomes and complications of the Yamane IOL implantation technique.
Methods: A retrospective study of 21 eyes of 21 patients that underwent scleral fixation of IOL by the Yamane technique was observed. Demographic data, primary indications for surgery, best corrected visual acuity (BCVA), intraocular pressure (IOP) pre-operative and post-operative during follow-up, and complications were also analyzed.
Results: Twenty-one patients were included, with an average age of 52.57±23.41 years old. Eleven eyes with lens subluxation (52.4%), 9 eyes with aphakia (42.9%), and 1 eye with phacodonesis (4.8%) were indicated for the Yamane technique of SFIOL in this study. The preoperative mean BCVA was 2.2±0.9 LogMAR, while the 1-month postoperative BCVA was 1.1±0.9 LogMAR. The mean preoperative IOP was 15.81±6.7 mmHg, and the 1-month postoperative IOP was 16.00±7.7 mmHg. This study found that there was a significant improvement in BCVA with p=0.00 (p<0.05), and there was no significant postoperative IOP spike with p=0.88 (p<0.05). The main complications observed in this study were corneal edema (23.8%) and postoperative IOP spike (14,3%).
Conclusion: The Yamane SFIOL technique is a relatively safe approach for the surgical management of patients who need secondary IOL implantation with significantly improved visual function without significant complications.
