A total of 51 children (51 eyes) were enrolled. Repeated measurements of flat (K1) and steep (K2) corneal radius, white-to-white (WTW) distance and axial length (AL) were performed with the Myah device. The same parameters were obtained from a subgroup (30 eyes) with the Myopia Master for the agreement analysis. The repeatability was assessed using the intrasubject standard deviation (Sw) and the intraclass correlation coefficient (ICC). The agreement was analyzed using the Bland\u2013Altman method and the paired Student t-test. The Sw was 0.018 D, 0.021 D, 0.071 mm and 0.017 mm for K1, K2, WTW and AL, respectively (ICC \u2265 0.971). The mean difference and limits of agreement when comparing instruments were \u22120.013 (\u22120.102\/0.077) for K1 (p = 0.16), \u22120.058 (\u22120.127\/0.012) for K2 (p &lt; 0.001), 0.151 (\u22120.370\/0.673) for WTW (p &lt; 0.001) and 0.030 (\u22120.091\/0.151) for AL (p = 0.009). In conclusion, the Myah device provides consistent measurements of corneal radius, WTW distance and AL in a healthy pediatric population, validating their usefulness in clinical practice. These measurements could be used interchangeably with those provided by the Myopia Master device, although with some caution.<\/jats:p>","DOI":"10.3390\/children9111713","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T02:34:52Z","timestamp":1667961292000},"page":"1713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Clinical Validation of a New Optical Biometer for Myopia Control in a Healthy Pediatric Population"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3765-2478","authenticated-orcid":false,"given":"Elena","family":"Mart\u00ednez-Plaza","sequence":"first","affiliation":[{"name":"Group of Optics and Visual Perception, Department of Optics, Pharmacology and Anatomy, University of Alicante, 03690 Alicante, Spain"},{"name":"University of Valladolid, 47001 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4854-3592","authenticated-orcid":false,"given":"Ainhoa","family":"Molina-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Group of Optics and Visual Perception, Department of Optics, Pharmacology and Anatomy, University of Alicante, 03690 Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfonso","family":"Arias-Puente","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Vithas Medimar International Hospital, 03016 Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1546-4807","authenticated-orcid":false,"given":"David P.","family":"Pi\u00f1ero","sequence":"additional","affiliation":[{"name":"Group of Optics and Visual Perception, Department of Optics, Pharmacology and Anatomy, University of Alicante, 03690 Alicante, Spain"},{"name":"Department of Ophthalmology, Vithas Medimar International Hospital, 03016 Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1036","DOI":"10.1016\/j.ophtha.2016.01.006","article-title":"Global prevalence of myopia and high myopia and temporal trends from 2000 through 2050","volume":"123","author":"Holden","year":"2016","journal-title":"Ophthalmology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"M89","DOI":"10.1167\/iovs.18-25965","article-title":"IMI\u2014Myopia Genetics Report","volume":"60","author":"Tedja","year":"2019","journal-title":"Investig.
