This study compares the agreement of two SS-OCT devices, the Eyestar 900 (Haag-Streit, K\u00f6niz, Switzerland) and the Anterion (Heidelberg Engineering, Heidelberg, Germany).<\/jats:p><jats:p>\n          Materials and Methods All patients undergoing cataract surgery or seeking consultation for corneal abnormalities between January 2024 and May 2024 were eligible for inclusion. Both eyes were included in the final analysis.<\/jats:p><jats:p>\n          Results A sample of 86 eyes from 43 patients was analysed. The mean differences (ES-AN) across all data between the Eyestar 900 (ES) and Anterion (AN) were as follows: anterior chamber depth (ACD) \u2212\u20090.080\u2009mm (ICC &gt;\u20090.926), axial length (AL) 0.015\u2009mm (ICC &gt;\u20090.99), central corneal thickness (CCT) 0.914\u2009\u00b5m (ICC &gt;\u20090.921), corneal curvature along the flat meridian (K1) \u2212\u20090.024\u2009D (ICC &gt;\u20090.904), and steep meridian (K2) \u2212\u20090.210\u2009D (ICC &gt;\u20090.902), white-to-white corneal diameter (WTW) 0.215\u2009mm (ICC &gt;\u20090.81). There was excellent agreement for ACD, AL, CCT, K1, K2, and WTW. However, the corneal axis (AX) showed only moderate agreement (ICC &gt;\u20090.389), with a mean difference of 5.97\u00b0 and a notable standard deviation of 58.6\u00b0.<\/jats:p><jats:p>\n          Conclusions The Eyestar 900 and Anterion demonstrated substantial agreement for all parameters except for the corneal meridian axis. It may be assumed that the inclusion of eyes with irregular corneal topographies may have contributed to this discrepancy.<\/jats:p><jats:p>\n          Summary Overall, there was a high level of agreement between the Eyestar 900 and Anterion. It is reasonable to assume that the measurement outcomes provided by both devices are interchangeable for the calculation of target refractive outcomes for intraocular lenses, with no clinically relevant differences.<\/jats:p>","DOI":"10.1055\/a-2463-4061","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T00:02:35Z","timestamp":1733875355000},"page":"357-362","source":"Crossref","is-referenced-by-count":1,"title":["Comparison
