The order of scans was randomized. Repeatability was assessed using within-subject standard deviation (Sw) and intraclass correlation coefficient (ICC). Bland\u2013Altman analysis was used to assess the 95% limits of agreement.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Eyestar 900 had comparable repeatability to Anterion and MS-39 across groups. ICC was overall >0.8. Pentacam AXL Wave had lower Sw (better repeatability) across all groups. In normal eyes, Eyestar 900 can be used interchangeably with MS-39 and Anterion (\n P<\/jats:italic>\n > 0.23). Eyestar 900 and Pentacam AXL Wave did not show agreement on any parameter, except anterior chamber depth (ACD) (\n P<\/jats:italic>\n = 0.92). Eyestar 900 in KC eyes can be used interchangeably with MS-39, except for posterior keratometry (pK) and thinnest corneal thickness (TCT) (\n P<\/jats:italic>\n < 0.001), and with Anterion, except for TCT and ACD (\n P<\/jats:italic>\n < 0.001). In post-refractive eyes, Eyestar 900 can be used interchangeably with MS-39, except for pK (\n P<\/jats:italic>\n < 0.001), and with Anterion, except for ACD (\n P<\/jats:italic>\n < 0.001). Pentacam AXL Wave and Eyestar 900 cannot be used interchangeably in KC and post-refractive eyes.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Newer devices such as Eyestar 900 can be used interchangeably with Anterion and MS-39 in normal eyes and partly in KC and post-refractive eyes. Pentacam AXL Wave and Eyestar 900 cannot be used interchangeably across the various groups. However, these multifunctional hybrid tools of combined topography, AS-OCT, can be helpful in refractive clinics.<\/jats:p>\n
