Fig. 3

Double-angled plots of preoperative and postoperative astigmatism in eyes that underwent laser in situ keratomileusis (LASIK) and Artisan lens implantation for the management of refractive error after penetrating keratoplasty for keratoconus. Each concentric circle represents 1 D astigmatism magnitude. The ellipses surrounding the centroids indicate the standard deviations of the x and y coordinates
