Abstract

Background: Worldwide, among diabetic patients, 60% complain of cataract (18 million all over the world). Furthermore, cataract is considered one of the common causes of vision loss, especially in those who are diabetic.
Aim of the work: The present study aims at evaluating corneal endothelial variations after uncomplicated cataract removal by Phacoemulsification for Type II diabetic patients with preoperative different levels of HbA1c.
Patients and Methods: In the present study 60 eyes of 60 diabetic patients have nuclear cataract grades II or III were underwent cataract extraction surgery using phacoemulsification technique.
Results: The mean of both Endothelial Cell Density (ECD) and percentage of hexagenality (HEX% %) dropped in all patients; this drop is significantly higher in patients with HbA1c > 7 than those with HbA1c < 7. On the other hand, the mean of the Coefficient of variation (CV%) increases in all patients; this increase is more in patients with HbA1c > 7 than those with HbA1c < 7.
Conclusion: Cataract phacoemulsification causes damage to the corneal endothelium in diabetics. It appeared that the injury of the endothelium of patients with HbA1c < 7 % was less than that of those with HbA1c >7.
