The rapid control group consisted of 152 patients (222 eyes) with HbA1c > 9.0% following rapid glycemic control (average duration: 17.3 ± 6.6 days), and the basic control group consisted of 111 patients (162 eyes) with HbA1c < 7.0%. Complications and visual outcomes were analyzed between the two groups during the 6-month postoperative follow-up.Results: Macular edema and vitreous hemorrhage were the main postoperative complications in rapid control group (11.7%) and basic control group (4.9%) (P = 0.021). Linear Mixed-effects Models analysis showed that rapid glycemic correction (Odds ratio [OR] = 6.525, 95% confidence interval [CI] = 2.927– 14.547, P
