The quality of the included studies was assessed using the Newcastle-Ottawa Scale.</p><p><strong>Results: </strong>A total of 57 studies were included and critically evaluated in the meta-analysis. The results showed that female sex was associated with a lower risk of endophthalmitis (odds ratio [OR]: 0.81; 95% CI: 0.75-0.87; p < 0.001). Individuals with diabetes who underwent cataract surgery were found to have a greater risk of endophthalmitis (I2 = 95%; OR: 4.90; 95% CI: 2.41, 9.95; p < 0.001), but the result may be influenced by publication bias. Individuals with hypertension (OR: 2.88; 95% CI: 1.53, 5.45; p = 0.001) and intraoperative PCR (OR: 9.18; 95% CI: 3.31, 25.43; p < 0.001) were found to have a greater risk of endophthalmitis. Phacoemulsification significantly reduced the risk of endophthalmitis compared with extracapsular cataract extraction (ECCE) (OR: 0.62; 95% CI: 0.45, 0.85) based on network meta-analysis.</p><p><strong>Conclusion: </strong>Male sex, hypertension, intraoperative PCR, and the use of the ECCE surgical approach are associated with a greater risk of postoperative endophthalmitis. Although an age-related trend in elevated risk was observed, this finding should be interpreted cautiously.</p>","PeriodicalId":19662,"journal":{"name":"Ophthalmic Research","volume":" ","pages":"117-136"},"PeriodicalIF":2.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11844714/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142952573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
