Mean binocular uncorrected intermediate visual acuity at 66 cm at 6 months postoperatively was 0.18 ± 0.13 logarithm of the minimum angle of resolution (20/30 Snellen).</p><p><strong>Conclusions: </strong>Tilt and decentration of the Clareon TIOL were generally low and a strong correlation was found between crystalline lens tilt and TIOL tilt at 6 months.</p>","PeriodicalId":16951,"journal":{"name":"Journal of refractive surgery","volume":"41 9","pages":"e906-e916"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145023592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
