Abstract
Diabetic retinopathy (DR) is a major complication of diabetes mellitus, causing significant vision impairment. Intra ocular lens (IOL) implantation after cataract surgery has improved visual outcomes, but its impact on DR progression is uncertain. This study aims to assess DR progression post‐IOL implantation and identify associated risk factors. This longitudinal, observational study included 120 participants, split evenly between a diabetic group with existing DR and a control group without diabetes. Inclusion criteria were age 50‐80 years and indication for cataract surgery. Exclusion criteria included other ocular pathologies and severe systemic diseases. All surgeries were performed using standardized phacoemulsi fication techniques, with random assignment to one of three IOL types. Participants were followed for 36 months, with assessments at 6, 12, 24 and 36 months. Outcomes included DR progression (classified using ETDRS criteria) and visual acuity (logMAR). Statistical analysis was performed using SPSS. The diabetic group had higher baseline HbA1c levels (8.5% vs. 5.7%, P<0.001) and worse visual acuity (0.6 vs. 0.3 logMAR, P<0.001). DR progression was observed at each follow‐up, with mild NPDR decreasing from 33.3% at baseline to 16.7% at 36 monthsPDR increasing from 16.7% to 25%. Visual acuity improved initially but plateaued, with the diabetic group showing significant improvement at each time point compared to the control group (P<0.001). Significant risk factors for DR progression included longer diabetes duration (OR=1.05, P<0.001), higher HbA1c (OR=1.10, P<0.001) and preoperative DR severity (OR=2.20, P<0.001). IOL type did not significantly affect DR progression. DR progression post‐IOL implantation is influenced by diabetes duration, glycemic controlpreoperative DR severity. Although IOL type did not impact DR progression, careful monitoring and management are essential for optimizing visual outcomes in diabetic patients undergoing cataract surgery.
