Purpose
To assess the rate of treatment-requiring diabetic macular edema (TR-DME) in eyes after cataract surgery, thus provide the strategy of the prevention and the clinical decision-making.
Setting
A retrospective study
Methods
This was a retrospective study involving patients with diabetes who undergoing cataract surgery in Shaanxi Eye Hospital from January 2019 to December 2021.The rate and treatment of developing first episode of TR-DME in relation to timing of cataract surgery were observed.
Results
A total of 1819 individuals (3594 eyes) were included in this study. The rate of developing TR-DME was 0.7% in the year prior to surgery versus 2.3% in the year after surgery (p<0.05). The highest risk period was between 2 and 4 months after surgery, accounting for 61.9% of the TR-DME patients. 49 eyes developing first episode of TR-DME after delayed sequential bilateral cataract surgery. Four groups were divided according to the interval between bilateral cataract surgery, TR-DME has a greater incidence for shorter-than-2 weeks sequential bilateral cataract surgery. Retina specialists tended to extend the interval between bilateral cataract surgery compared to cataract and glaucoma specialists.
Conclusions
This is the first report in a real world that the effect of cataract surgery on DME currently presented in a single biggest ophthalmic center in northwest of China. The rate of developing DME increased significantly after cataract surgery, the highest risk period was between 2 and 4 months after surgery. Patients with shorter interval between bilateral cataract surgery are at high risk.
