This paper presents an algorithm\n\t\t\t\t\tand software for correcting the distortion using only two simple\n\t\t\t\t\tmeasurements in which a readily available standard sphere is\n\t\t\t\t\tpositioned in different depths in front of the OCT scanner. This\n\t\t\t\t\toffers a highly accessible and easily reproducible method for the\n\t\t\t\t\tfield distortion correction (FDC). The correction was validated by\n\t\t\t\t\tmeasuring different spherical phantoms and conducting corneal\n\t\t\t\t\tcurvature measurements of\n                    <jats:italic toggle=\"yes\">ex vivo<\/jats:italic>\n                    porcine corneas using a commercial spectral-domain OCT system and a\n\t\t\t\t\tclinically approved swept-source OCT as a reference instrument. Thus,\n\t\t\t\t\tthe error in radius measurements of spherical phantoms was reduced by &gt;90% and astigmatism by &gt;80% using FDC. In explanted porcine eyes,\n\t\t\t\t\tthe error in astigmatism measurements with the Telesto was reduced by\n\t\t\t\t\t75% for power and 70% for angle. The best fitting sphere radius was\n\t\t\t\t\tdetermined up to a deviation of 0.4% from the Anterion. This paper\n\t\t\t\t\tdescribes a correction algorithm for OCT immanent distortion that is\n\t\t\t\t\tapplicable to any scanning OCT setup and enables precise corneal\n\t\t\t\t\tcurvature measurements. The MATLAB software for the FDC is publicly\n\t\t\t\t\tavailable on GitHub.\n                  <\/jats:p>","DOI":"10.1364\/ao.505107","type":"journal-article","created":{"date-parts":[[2024,3,12]],"date-time":"2024-03-12T10:00:09Z","timestamp":1710237609000},"page":"2694","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Algorithm and software for field distortion correction in a commercial SD-OCT for corneal curvature assessment"],"prefix":"10.1364","volume":"63","author":[{"given":"Maron","family":"Dolling","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00t3r8h32","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical Laser Center L\u00fcbeck GmbH"},{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lara","family":"Buhl","sequence":"additional","affiliation":[{"name":"Harvard Medical School"},{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reginald","family":"Birngruber","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00t3r8h32","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical Laser Center L\u00fcbeck GmbH"},{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5051-3037","authenticated-orcid":true,"given":"Gereon","family":"H\u00fcttmann","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00t3r8h32","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical Laser Center L\u00fcbeck GmbH"},{"name":"Airway Research Center North Member of the German Center for Lung Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4389-9151","authenticated-orcid":true,"given":"Hinnerk","family":"Schulz-Hildebrandt","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00t3r8h32","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical Laser Center L\u00fcbeck GmbH"},{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,3,27]]},"reference":[{"key":"ao-63-10-2694-R1","doi-asserted-by":"publisher","first-page":"051403","DOI":"10.1117\/1.2793736","volume":"12","author":"Zysk","year":"2007","journal-title":"J.
