The central 6 mm of the 29-year-old OCM lens (dashed line) was fit to conic sections (red and blue) similar to those used by Hermans et al (2006). The equatorial region was modeled with two conic functions (green and cyan) whose derivatives were set to be continuous with the central conics. The radii of curvature obtained with these fits were 8.03 mm for the anterior surface and −r the posterior surface.
