To compare measurements of anterior and posterior keratometric values, using a color light-emitting diode corneal topographer and a dual rotating Scheimpflug\u2013Placido topographer. <jats:italic>Methods<\/jats:italic>. Anterior and posterior corneal index measurements were performed using a color light-emitting diode corneal topographer (Cassini) and a dual rotating Scheimpflug\u2013Placido topographer (Galilei G4) and then compared. The paired <jats:italic>t<\/jats:italic>-test, intraclass correlation coefficients (ICCs), and Bland\u2013Altman plots were used to evaluate the agreement between measurements. <jats:italic>Results<\/jats:italic>. Sixty postrefractive surgery eyes and 60 normal eyes were evaluated. Both the color light-emitting diode corneal topographer and the dual rotating Scheimpflug\u2013Placido topographer provided highly repeatable corneal measurements (ICC &gt; 0.969). The agreement levels between the 2 devices for anterior corneal power, astigmatism magnitude, and <jats:italic>J<\/jats:italic>0 and <jats:italic>J<\/jats:italic>45 values were ICC &gt; 0.906 for the total group. However, the ICC values for posterior corneal power, astigmatism magnitude, and <jats:italic>J<\/jats:italic>0 and <jats:italic>J<\/jats:italic>45 values were lower than 0.681 for the total group. <jats:italic>Conclusions<\/jats:italic>. The anterior keratometric values obtained by the color light-emitting diode corneal topographer and the dual rotating Scheimpflug\u2013Placido topographer showed high agreement levels, but the posterior keratometric values showed lower agreement levels.<\/jats:p>","DOI":"10.1155\/2018\/6764805","type":"journal-article","created":{"date-parts":[[2018,12,27]],"date-time":"2018-12-27T18:30:47Z","timestamp":1545935447000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of Color Light-Emitting Diode Corneal Topographer and Dual Rotating Scheimpflug\u2013Placido Topographer"],"prefix":"10.1155","volume":"2018","author":[{"given":"Jae Hyuck","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong Soo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Pusan National University Hospital, Pusan National University School of Medicine and Medical Research Institute, Yangsan, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael C.","family":"Knorz","sequence":"additional","affiliation":[{"name":"Medical Faculty Mannheim of the University of Heidelberg, Mannheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6927-5251","authenticated-orcid":true,"given":"Gerd U.","family":"Auffarth","sequence":"additional","affiliation":[{"name":"International Vision Correction Research Centre (IVCRC), David J.
