Only complete scans with at least 3 successful measurements for each eye performed on the same day were considered. The mean (Mean) and standard deviations (SD) for each sequence of measurements were derived and analysed. Correlations between the uncertainties were assessed using Spearman rank correlations.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>In the dataset with 677 eyes matching the inclusion criteria, the within subject standard deviation and repeatability for all parameters match previously published data. The SD of the axial length (AL) increased with the Mean AL, but there was no noticeable dependency of the SD of any of the other parameters on their corresponding Mean value. The SDs of the parameters are not independent of one another, and in particular we observe correlations between those for AL, anterior chamber depth, aqueous depth, lens thickness and corneal thickness.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The SD change over Mean for AL measurement and the correlations between the uncertainties of several biometric parameters mean that a simple Gaussian error propagation model cannot be used to derive the effect of biometric uncertainties on the predicted intraocular lens power and refraction after cataract surgery.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0297869","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T18:46:20Z","timestamp":1707417980000},"page":"e0297869","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":20,"title":["Repeatability of biometric measures from the IOLMaster 700 in a cataractous population"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9175-6177","authenticated-orcid":true,"given":"Achim","family":"Langenbucher","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00f3ra","family":"Szentm\u00e1ry","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0779-7449","authenticated-orcid":true,"given":"Alan","family":"Cayless","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Hoffmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4145-2559","authenticated-orcid":true,"given":"Jascha","family":"Wendelstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Cooke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,2,8]]},"reference":[{"issue":"3","key":"pone.0297869.ref001","doi-asserted-by":"crossref","first-page":"206","DOI":"10.3928\/1081597X-20130129-07","article-title":"Refractive error assessment: influence of different optical elements and current limits of biometric techniques.","volume":"29","author":"F Ribeiro","year":"2013","journal-title":"J Refract Surg"},{"key":"pone.0297869.ref002","article-title":"Impact of uncertainties in biometric parameters on intraocular lens power formula predicted refraction using a Monte-Carlo simulation.","author":"A Langenbucher","year":"2023","journal-title":"Acta Ophthalmol"},{"issue":"3","key":"pone.0297869.ref003","doi-asserted-by":"crossref","first-page":"368","DOI":"10.1016\/j.jcrs.2007.10.031","article-title":"Sources of error in intraocular lens power calculation","volume":"34","author":"S.
