Abstract
Posterior capsular opacification (PCO), or secondary cataract, is a frequent postoperative complication of cataract surgery, characterized by the proliferation of lens epithelial cells (LECs) on the posterior capsule, leading to decreased visual acuity. The choice of intraocular lens (IOL) material and design significantly affects the incidence and severity of PCO. This study compares the incidence and severity of PCO between patients implanted with foldable acrylic and PMMA (polymethyl methacrylate) IOLs. This prospective, comparative study involved 140 subjects who underwent cataract surgery with IOL implantation. Subjects were divided into two groups: Group A (PMMA IOL) with 70 patients and Group B (foldable acrylic IOL) with 70 patients. Inclusion criteria included patients aged 40‐80 years with no prior ocular surgery or significant ocular comorbidities. Patients were followed up at 6 months, 1 year2 years postoperatively. PCO was graded based on its visual significance and extent. Statistical analysis compared PCO incidence, time to PCO development, visual acuity intervention rates. The overall incidence of PCO was significantly higher in the PMMA group (35%) compared to the foldable acrylic group (15%). The time‐based incidence of PCO showed a progressive increase, with PMMA IOLs consistently demonstrating higher rates at each interval. Severity grading indicated more moderate and severe PCO cases in the PMMA group. Complications such as visual acuity reduction and the need for Nd laser capsulotomy were more prevalent in the PMMA group. Foldable acrylic IOLs significantly reduce the incidence and severity of PCO compared to PMMA IOLs. Despite their higher initial cost, foldable acrylic IOLs offer substantial benefits in terms of patient outcomes and reduced need for secondary interventions. These findings support the preference for foldable acrylic IOLs in clinical practice to enhance postoperative visual outcomes and patient satisfaction.
