Abstract: Objective:To explore the clinical safety and effects of blood glucose intervention nursing in perioperative patients with diabetes complicated with cataract.Methods:One hundred and eighteen patients(132 eyes) with diabetes complicated with cataract were divided randomly into the conventional glucose control group(control group,66 years in 60 cases) and intensive blood sugar treatment group(treatment group,66 years in 58 cases).The levels of blood sugar in all patients were effectively controlled before operation,then the patients were treated with phacoemulsification combined with intraocular lens implantation.The postoperative corrected visual acuity,hospital stay,complication,satisfaction and clinical efficacy between two groups were observed.Results:The postoperative corrected visual acuity and hospital stay in observation group were better and shorter those in control group,respectively(P<0.01).The total incidence of the bleeding,infection,oedema,adhesion and inflammatory response in observation group was lower than that in control group(P<0.01).The total effective rate and satisfaction in observation group(98.3% and 98.3%) were higher than those in control group(86.7% and 88.7%),respectively(P<0.05).Conclusions:The blood glucose intervention nursing in perioperative patients with diabetes complicated with cataract is conducive to increasing vision,decreasing the incidence of adverse reaction and effectively improving the life quality of patients.
