方法：利用Meta分析方法分析国内5篇关于白内障术后眼内炎发病危险因素的研究文献。

结果：年龄(≥70岁)、糖尿病史、玻璃体溢出、手术时间(≥10min)、普通手术室及控制麻醉剂时效的合并OR值(95%CI)分别为：1.81(1.43～1.69)，3.66(1.64～8.16)，2.21(1.46～3.32)，3.54(2.47～5.06)，2.77(2.07～3.72)，2.09(1.53～2.86)。

结论：年龄(≥70岁)、糖尿病史、玻璃体溢出、手术时间(≥10min)、普通手术室及控制麻醉剂时效是白内障术后眼内炎发病的主要危险因素。

METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.

RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic were 1.81(95% CI: 1.43-1.69),3.66(95% CI: 1.64-8.16),2.21(95% CI: 1.46-3.32),3.54(95% CI: 2.47-5.06),2.77(95% CI: 2.07-3.72),2.09(95% CI: 1.53-2.86).

CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.
