A Study of Visual Outcomes After Implantation of Presbyopia-Correcting Intraocular Lenses

Abstract

Introduction: Presbyopia is a prevalent refractive condition affecting individuals over 40, necessitating effective management strategies. This study evaluates visual outcomes following the implantation of presbyopia-correcting intraocular lenses (IOLs) during cataract surgery. Material and Methods: A prospective observational study was conducted from September 2022 to February 2024, including 84 patients aged over 40 with age-related cataracts. Preoperative assessments were followed by sutureless phacoemulsification surgery with presbyopia-correcting IOL implantation. Visual acuity, contrast sensitivity, and complications were assessed preoperatively, one month, and three months post-operatively. Results: The mean age of participants was 55.6 years, with 78.6% achieving best-corrected visual acuity (BCVA) of 6/6 by one month and 91.7% by three months. Significant improvements were noted in both distant and near vision (p < 0.001). Contrast sensitivity scores showed 99.0%, scoring 2.0 or above by three months. Complications were minimal; 91% experienced no early complications, and 93% reported no late complications, with posterior capsule opacification observed in 7%. Conclusion: Presbyopia-correcting IOLs effectively improve visual outcomes post-cataract surgery, demonstrating high patient satisfaction and low complication rates
