The participants included 1423 eyes undergoing elective intraocular surgeries (eg, cataract, keratoplasty, and trabeculectomy) or receiving intravitreal injections.

Although PVI is widely recognized as an essential prophylactic measure, the role of preoperative topical antibiotics remains debated.

A ray-tracing model to back-calculate the corneal power from the observed postoperative refraction and AL was also included.</p><p><strong>Results: </strong>In 52 eyes of 52 patients, mean prediction errors for the Hoffer Q, Holladay 1, SRK/T, Haigis, Barrett Universal II, and the Olsen formulas were +1.48 D, +1.15 D, +0.91 D, +0.65 D, +0.15 D, and +0.11 D, respectively using standard AL, and after SOS correction of the AL, the mean errors changed to +1.08 D, +0.75 D, +0.52 D, +0.26 D, -0.25 D, and -0.27 D, respectively. The mean back-calculated corneal power was 1.25 D lower than the mean keratometer reading using the standard keratometric index of 1.3375 and corresponded to an effective index of 1.328.</p><p><strong>Conclusions: </strong>The hyperopic error commonly seen in highly myopic eyes with classic thin-lens formulas is only partly corrected by SOS recalibration of the AL. We suggest the source of the residual error is an incorrect keratometric index.</p>","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":"388-393"},"PeriodicalIF":2.6,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065823","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}
