A total of 15 eyes were scanned with the Visante Omni. A lid speculum was used to keep the rabbits' eye open during the measurements to ensure that the eyelids did not block the 10-mm diameter mapping area. The cornea was kept wet regularly with balanced salt solution to prevent the ocular surface from drying. First, the cornea was scanned with ATLAS corneal topographer, incorporated with the Visante Omni, where 8000 data points of the anterior corneal surface were recorded. The anterior corneal topography data were then transferred to the Visante OCT station via a network link. The rabbit was then moved to the Visante OCT station to scan for global pachymetry. Pachymetry alignment with anterior corneal surface data, obtained from the ATLAS corneal topographer, required the observer to locate the center of the pupil, which was achieved when the vertex produced a vertical white line behind the center of the cornea. Thereafter, the Visante OCT system would lock onto the vertex and track it so that the pachymetric data could be recorded. The pachymetry scan comprised of 2048 data points from 16 meridional scans. The construction of the posterior corneal elevation and curvature was performed by the in-built Visante Omni software (version 3.0). Three quantitative parameters were then obtained and analyzed; anterior axial curvature (steep K and flat K), anterior elevation (steep K and flat K), and posterior elevation (steep K and flat K). Two trained, independent, masked observers (AR and RB) performed and reviewed the corneal scans. Each eye had a set of five readings taken over a day by each observer. One week later, each observer repeated the biometric measurements to assess the intraobserver reproducibility.
