Repeatability and agreement of a new anterior segment optical coherence tomography with standard devices in normal, keratoconus, and post-refractive eyes

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.
