ObjectiveTo compare the mean change in Corneal Endothelial cell Density (CED), from baseline (pre-operative value), two months after phacoemulsification cataract surgery between type II diabetic patients and non-diabetic patients.MethodsThis prospective stratified controlled study was conducted at PNS Shifa Hospital, Karachi. 80 eyes of 72 type II diabetic patients and 80 eyes of 77 non diabetic controls, having Nuclear Opalescence (NO) grades 2 and 3 on slit lamp examination underwent phacoemulsification surgery. CED was measured in cells/mm2, of concerned eye of each subject preoperatively and 2 months post operatively using specular microscope. The difference in mean CED change between the two groups after surgery was analyzed.ResultsMean age of study population was 61.41± 6.76 years. Out of study population, 92 (57.5%) were males and 68 (42.5%) were females. There was a statistically significant difference between both groups in terms of mean post-operative CED, mean change in CED and mean frequency change in CED (p <0.05). There was no statistically significant difference between both groups in age, gender, laterality of eyes and mean pre-operative CED, (p >0.05). Difference of pre-operative CED from post-operative CED in each group was statistically significant.ConclusionThere is a significant difference between diabetic population and normal population in terms of corneal endothelial loss after uneventful phacoemulsification cataract surgery.
