Objective:To investigate the effect of phacoemulsification and intraocular lens implantation on diabetic retinopathy (DR) in type 2 diabetes.Methods:This was a retrospective case series study. A total of 272 eyes of 136 cases with type 2 diabetes mellitus who underwent phacoemulsification and intraocular lens implantation from Jan. 2018 to Jul. 2020 in Shanxi Eye Hospital were enrolled in this study. There were 130 eyes of 65 cases without DR and 142 eyes of 71 cases with DR. The progress of fundus lesions before and after operation was compared and the comparison was also analyzed between the surgical eyes and the contralateral eyes.Results:No fundus lesion was found in patients without DR at 6 months after operation. The progressive fundus lesions were found in 23 eyes of DR patients, including 21 eyes (29.58%, 21/71) in the surgical eye group and 2 eyes (2.82%, 2/71) in the contralateral eye group. The risk of developing DR in the surgical eye group was significantly higher than that in the contralateral eye group ( Z=-3.391, P<0.001). The correlation analysis of Spearman showed that the degree of DR before operation was significantly related to the progress rate of DR. Conclusion:Phacoemulsification and intraocular lens implantation can aggravate the progress of fundus lesions in DR patients. The degree of DR is the risk factor for the development of DR.

Objective:To investigate the efficacy of ambulatory surgery mode for macular hole retinal detachment in high myopia.Methods:The clinical data of 435 high myopia patients with macular hole retinal detachment in Shanxi Eye Hospital from Jan. 2018 to Dec. 2019 were retrospectively analyzed. All patients were treated with vitrectomy combined silicone oil tamponade. The patients were divided into two groups according to the operation mode. In the control group, 342 cases were treated with routine inpatient operation mode, and in the study group, 93 cases were treated with ambulatory surgery mode. The average length of stay, hospital costs, patients’overall satisfaction, postoperative compliance and complications were compared between the two groups.Results:Compared with the control group, the average length of stay and hospital costs of the study group were significantly reduced, and the difference was statistically significant ( P<0.05). Retinal reattachment and macular hole closure were observed in both groups at 3 months after operation. The overall satisfaction of the study group was higher than that of the control group ( P<0.05) . However, there was no significant difference in postoperative compliance and complication rate between the two groups. Conclusion:The clinical effect of ambulatory surgery for patients with high myopia macular hole retinal detachment is consistent with the inpatient operation, which can effectively shorten the hospitalization time of patients, reduce patient treatment costs, increase medical resource utilization, and improve the satisfaction of patients. It is a safe, effective, convenient and humanized treatment mode.
