Abstract
Cataract is the leading cause of blindness worldwide. Phacoemulsification is the most widely utilized surgical technique that uses ultrasonic energy to emulsify the lens darkened by cloudy imperfections, and the clouded lens is then replaced with an intraocular lens. With the refinement of the phacoemulsification technique, cataract surgery has undergone a remarkable development. Diabetic patients pose a particular challenge because of the tendency for early formation of cataract in them and propensity to develop corneal edema after cataract surgery. Diabetes mellitus also has been found to be detrimental to the corneal endothelium. Patients with diabetes have been found to have morphologically abnormal endothelium including pleomorphism and polymegethism. Thus, an elderly patient with diabetes undergoing phacoemulsification is particularly vulnerable to greater endothelial damage during surgery. Specular microscopy is a photographic, non contact approach for seeing and assessing the morphological characters of the endothelial cells (number, shape and size), by using computer-assisted analysis of endothelial morphology. The device illuminates the corneal surface and takes pictures of the endothelial/aqueous interface. The goal of this study was to investigate the correlation between postoperative central corneal thickness, the changes of corneal endothelial cell density and characters after phacoemulsification in diabetic patients by using specular microscopy.
