Objective To investigate the effects of phacoemulsification on macula in diabetics． Methods Thirty eyes of cataract in diabetics were chosen randomly for measurement of the thickness of fovea of retina using OCT before phacoemulsification and 1 month after surgery ． The other eyes in these patients and 30 eyes of cataract in nondiabetic pati ents with phacoemulsification were as control． Results In 30 eyes of diabetics with phacoemulsification, the mean fovea thickness were (148．5 plusmn;27．7)  mu;m preoperatively and (219．4 plusmn;68．23)  mu;m postoperatively, and the difference was significant　(P lt;0．05)． In 30 eyes of diabetics without surgery, the mean foveal thickness were (147.4 plusmn;27.5)  mu;m preoperatively and (148.2 plusmn;27.3)　 mu;m postoperatively and the difference was not significant　(P gt;0．05)． In 30 eyes of cataract in nondiabetic patients, the mean fovea thickness were (142．37 plusmn;12．7)　 mu;m preoperatively and (151．9 plusmn;23．7)　 mu;m postoperatively and the difference was not significant　(P gt;0．05)． In 30 eyes of diabetic s with phacoemulsification, 11 eyes had new macula edema after surgery and 3 eye s had significant retinal thickening． In 6 eyes with macular edema before surgery, the macular edema were aggravated in 3 eyes after surgery． The macular stru ctural changes were not found in two control groups． Conclusion The thickness of retina is inreased after phacoemulsification in deabetics,and morbidity and its severity of postopevative macular edema are increas ed as well． (Chin J Ocul Fundus Dis, 2001,17:175-177)
