Abstract

Background and aim: The ultrasonic energy used in phacoemulsification surgery might cause damage to the corneal endothelium. This study used specular microscopy prior to and after phacoemulsification to assess corneal endothelial alterations in diabetes and non-diabetic eyes. Patient and methods: A total of 60 patients with cataract were scheduled for phacoemulsification. They were divided into group 1 (33 eyes of 30 non-diabetic patients) and group 2 (33 eyes of 30 controlled diabetic patients). Uncorrected and best-corrected visual acuity were evaluated. Anterior, posterior corneal surfaces, and anterior chamber depth were examined. Specular microscopy was used preoperatively and at 1 week, 1 month, and 3 months post-operatively. Results: BCVA (best-corrected visual acuity), CCT (central corneal thickness), coefficient of variation (CV), and hexagonal cells (HEX%), the differences between both groups concerning preoperative and postoperative data were statistically not significant. No statistically significant difference in endothelial cell density (ECD) was found between both groups in preoperative values. While a statistically significant difference in ECD between both groups was found 1 month and 3 months following surgery. Conclusion: Diabetic corneas experience metabolic stress and lesser capacity for preservation than non-diabetic corneas. In comparison to non-diabetic ones, it demonstrated a slower rate of recovery following phacoemulsification.
