AIM: To investigate the effects of vitrectomy combined with cataract surgery on the corneal endothelial cells in diabetic retinopathy. <p>METHODS: A retrospective study was designed. 160 patients(160 eyes)with diabetic retinopathy from Jan 2015 to Feb 2017 were divided into two groups according to cataract. 74 patients(74 eyes)were operated on vitrectomy, and 86 patients(86 eyes)on vitrectomy combined with phacoemulsification cataract surgery and capsular bag implantation of foldable intraocular lens. To record the change of corneal endothelial cells density, average cellular area, coefficient of variation and percentage of hexagonal endothelial cell before and after treatment with Topcon corneal specular microscope. <p>RESULTS: Before and after surgery, the results of corneal endothelial cells density, average cellular area, coefficient of variation and percentage of hexagonal endothelial cell in simple vitrectomy group were no significant difference(<i>P</i>>0.05); After treatment corneal endothelial cells density and percentage of hexagonal endothelial cell were changed with statistical difference as the same as average cellular area and coefficient of variation(<i>P</i><0.05); There were significantly differences in corneal endothelial cells between two groups(<i>P</i><0.05). <p>CONCLUSION: It has certain influence on the corned endothelial cells when using vitrectomy combined with cataract surgery in diabetic retinopathy. For patients with indications, it should be paid attention to protecting the corneal endothelial cells.
