Objective To explore the application effect of conbercept combined with micro-incision phacoemulsification in patients with diabetic cataract.Methods A total of 80 patients(80 eyes)with diabetic cataract admitted in our hospital from June 2020 to December 2022 were selected as the research objects.According to different surgical methods,the patients were divided into control group(40 cases,40 eyes)and observation group(40 cases,40 eyes).The control group was treated with micro-incision phacoemulsification,and the observation group was treated with intravitreal injection of conbercept immediately after micro-incision phacoemulsification.The surgical effects of the two groups were compared.Results At 1 d and 1 week after operation,the best corrected visual acuity(BCVA)of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).At 1 d after operation,the intraocular pressure of the observation group was higher than that of the control group,and the difference was statistically significant(P<0.05).At 1 d,1 week and 1 month after operation,the subfoveal retinal thickness(SFRT)in the observation group was smaller than that in the control group,and the difference was statistically significant(P<0.05).At 3 months after operation,the macular vascular density(VD)in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).At 3 months after operation,there was a statistically significant difference in the incidence of iris neovascularization between the two groups(P<0.05).After operation,there was a statistically significant difference in the incidence of subconjunctival hemorrhage between the two groups(P<0.05).Conclusion The conbercept combined with micro-incision phacoemulsification in patients with diabetic cataract has better short-term efficacy.
