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.

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.
Comparison of the corneal endothelial cell density before-after cataract surgery
Comparison of the corneal endothelial cell density before-after cataract surgery，the density is expressed in terms of the number of cells per square millimeter.
Time frame: half year
Comparison of the endothelial cell size before-after cataract surgery
Comparison of the endothelial cell size before-after cataract surgery，the size is measured in square microns.
Time frame: half year
Comparison of the percentage of hexagonal cells before-after cataract surgery
Comparison of the percentage of hexagonal cells before-after cataract surgery,the percentage are expressed as "%".
Time frame: half year
Comparison of the central corneal thickness(CCT) before-after cataract surgery
Comparison of the central corneal thickness(CCT) before-after cataract surgery，the thickness is in microns.
Time frame: half year
