The most commonly used formulas are described and their accuracy evaluated in this study. Methods: This review includes papers evaluating the accuracy of intraocular lens power calculation formulas for children\u2019s eyes published from 2019\u20132024. The articles were identified by a literature search of medical and other databases (Pubmed\/MEDLINE, Crossref, Google Scholar) using the combination of the following key words: \u201cIOL power calculation formula\u201d, \u201cpediatric cataract\u201d, \u201ccongenital cataract\u201d, \u201cpediatric intraocular lens implantation\u201d, \u201clens power estimation\u201d, \u201cIOL power selection\u201d, \u201cphacoemulsification\u201d, \u201cHoffer Q\u201d, \u201cHolladay 1\u201d, \u201cSRK\/T\u201d, \u201cBarrett Universal II\u201d, \u201cHill-RBF\u201d, and \u201cKane\u201d. A total of 14 of the most recent peer-reviewed papers in English with the maximum sample sizes and the greatest number of compared formulas were considered. Results: The outcomes of mean absolute error and percentage of predictions within \u00b10.5 D and \u00b11.0 D were used to assess the accuracy of the formulas. In terms of MAE, Hoffer Q yielded the best result most often, just ahead of SRK\/T and Barrett Universal II, which, together with Holladay 1, most often yielded the second-best outcomes. Considering patients with PE within \u00b11.0 D, Barrett Universal II most often gave the best results and Holladay 1 most often gave the second-best. Conclusions: Barrett Universal II seems to be the most accurate formula for intraocular lens calculation for children\u2019s eyes. Very good postoperative outcomes can also be achieved using the Holladay 1 formula. However, there is still no agreement in terms of formula choice.<\/jats:p>","DOI":"10.3390\/jcm13154400","type":"journal-article","created":{"date-parts":[[2024,7,29]],"date-time":"2024-07-29T09:50:05Z","timestamp":1722246605000},"page":"4400","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Intraocular Lens Power Calculation Formulas in Children\u2014A Systematic Review"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3919-8339","authenticated-orcid":false,"given":"Wiktor","family":"Stopyra","sequence":"first","affiliation":[{"name":"MW-Med Eye Centre, 31-416 Krakow, Poland"},{"name":"Department of Medicine, University of Applied Sciences, 34-400 Nowy Targ, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3724-2391","authenticated-orcid":false,"given":"Andrzej","family":"Grzybowski","sequence":"additional","affiliation":[{"name":"Institute for Research in Ophthalmology, Foundation for Ophthalmology Development, 61-553 Poznan, Poland"},{"name":"Department of Ophthalmology, University of Warmia and Mazury, 10-720 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1136\/archdischild-2016-310532","article-title":"Epidemiology of blindness in children","volume":"102","author":"Solebo","year":"2017","journal-title":"Arch.
