Abstract

This study investigates the effects of glycemic control on refractive changes in diabetic patients, aiming to understand how fluctuations in blood sugar levels influence refractive errors and overall vision quality. Materials and methods: The study included 100 participants, divided into two groups based on their glycemic control: Group A (Controlled Glycemia) and Group B (Uncontrolled Glycemia). Over a 12-month period, data on HbA1c levels, fasting blood glucose, and refractive errors were collected and analyzed. Results: Group A, with better glycemic control, maintained stable HbA1c levels and experienced fewer significant refractive changes compared to Group B. Specifically, Group A had a lower incidence of refractive shifts of ≥0.50 diopters at all measured intervals (p < 0.05). Correlations between HbA1c levels and refractive changes were statistically significant, highlighting the impact of blood glucose management on refractive stability. Conclusion: The findings underscore the importance of stringent glycemic control in preventing vision-related complications in diabetic patients. Better glycemic management can minimize biochemical perturbations in the lens, thereby stabilizing refractive errors
