Abstract

Background:

Corneal endothelial tissues are susceptible to mechanical trauma from ultrasound energy during phacoemulsification. Several studies have reported various results of phacoemulsification effect on corneal endothelial cells between diabetic and non-diabetic patients.

Purpose:

To compare endothelial density, hexagonality, Coefficient of Variance (CV) and Central Corneal Thickness (CCT) changes between diabetic and non-diabetic patients at four weeks after phacoemulsification.

Methods:

Specular microscopy examinations prior to phacoemulsification and at four-weeks after phacoemulsification were performed on diabetic and non-diabetic groups with cataract. Later, patients in the diabetic group were divided based on their HbA1c level. The changes in endothelial density, the percentage of hexagonality, CV and CCT were evaluated.

Results:

At a four-weeks follow up, there were no statistical differences in endothelial cells density, CV and CCT changes between diabetic and non-diabetic groups. Mean (SD) of hexagonality percentage at four weeks of follow-up was lower (p-value=0.001) in diabetic group [(14.6) 41.7%] compared to non-diabetic group [(14.5) 50.1%]. There were no differences in endothelial cells density, hexagonality, CV and CCT values between the diabetic group with HbA1c level <7.5% and HbA1c level ≥7.5% at 4-weeks after phacoemulsification.

Conclusion:

There were no statistically significant differences in the endothelial loss, reduction of CV and CCT changes between the diabetic and non-diabetic group at four-weeks follow up after phacoemulsification. Diabetic group showed greater hexagonality decrease compared to non-diabetic group at four weeks after phacoemulsification. Different HbA1c levels did not affect the changes in endothelial density, the percentage of hexagonality, CV and CCT after phacoemulsification.
