Fig. 2

Analysis of the axial radius of curvature (ARC) from a composite anterior segment tomographic image. After removing the background noise, the shape of the outermost layer of the ocular surface was automatically extracted and curve-fitted using the image processing and optimization toolbox of MATLAB (MathWorks, Natick, MA) (bottom left). The axial curvature was then calculated mathematically as a function of the distance from the axis line (d, bottom right). The nARC[8] and tARC[8] were used for the correlation analysis
