Purpose To observe the changes of corneal endothelium in diabetes patients before and after cataract phacoemulsification surgery with confocal microscopy for exploring the variation and influencing factors．. Methods Phacoemulsification were randomly divided into 50 aged －related cataract patients with diabetes mellitus and 50 patients with senile.
“Microscopes are becoming significant adjuncts to improve refractive cataract surgery,” he says. Here are some of the latest advances. Figure 1.
