Corneal Endothelial Cell Changes After Phacoemulsification in Patients With Type 2 Diabetes Mellitus
Corneal Endothelial Cell Changes After Phacoemulsification in Patients With Type 2 Diabetes Mellitus
This study investigate the change of the corneal endothelial cells in patients with type 2
 diabetes after phacoemulsification with intraocular lens implantation.
The investigators do the clinical prospective study including 30 patients with type 2
 diabetes and 30 control patients without diabetes scheduled to undergo cataract surgery. The
 corneal endothelial cell density, variation in endothelial cell size (CV), percentage of
 hexagonal cells, and central corneal thickness(CCT) were recorded at baseline and at 3 months
 postoperatively.Then, the investigators compared the two sets of data. At last observing the
 change of the corneal endothelial cells in patients with type 2 diabetes after
 phacoemulsification with intraocular lens implantation.
