Interobserver agreement was high for AxL and IOL power measurements, with intraclass correlation coefficients of 0.854 preoperatively and 0.989 postoperatively. Manual adjustments resulted in significant AxL differences between pre- and post-treatment periods (p < 0.001), while automated Lenstar measurements remained consistent. Fellow eyes IOL and AxL remained identical in both preoperative and postoperative sessions (p = 0.323 for IOL and p = 0.287 for AxL).</p><p><strong>Conclusion: </strong>This preliminary observational study suggests that AxL and IOL power measurements remain stable following anti-VEGF therapy in most ME cases. Small but consistent AxL changes in eyes with high CRT may indicate a structural threshold for biometric variability. OLCR-based biometry remains reliable in real-world practice.</p>","PeriodicalId":9058,"journal":{"name":"BMC Ophthalmology","volume":"25 1","pages":"364"},"PeriodicalIF":1.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12220589/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538437","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}
