This review adheres to the PRISMA guidelines.</div></div><div><h3>Result</h3><div>This systematic review included two randomized controlled trials (RCTs) and five cohort studies (CS), analyzing a total of 702 eyes (352 eyes are treated with Ortho-K and BOZD ≤ 5.5 mm, 350 eyes are treated with Ortho-K and BOZD ≥ 6.0 mm). The findings indicate that the Ortho-K with smaller BOZD significantly reduces AL growth [<em>WMD</em> = −0.13, 95 %<em>CI</em> (−0.16 to −0.10), <em>P</em> &lt; 0.001].</div></div><div><h3>Conclusion</h3><div>The Ortho-K with smaller BOZD prove more effective in controlling myopic AL growth compared with larger BOZD. However, in clinical practice, it is necessary to comprehensively evaluating factors such as patient age, myopia diopter, pupil diameter, higher-order aberration, treatment zone area, and corneal eccentricity to achieve optimized outcomes in improving naked-eye vision and myopia controlling.</div></div>","PeriodicalId":49087,"journal":{"name":"Contact Lens & Anterior Eye","volume":"48 1","pages":"Article 102316"},"PeriodicalIF":4.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142478638","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}
