Fig. 2

Representative phase retardation en-face maps of (a) healthy cornea with normal thickness, (b) keratoconus cornea, (c) healthy thick cornea and (d) thick cornea with keratoconus. “Healthy” with respect to keratometry values. Phase retardation (PR) maps are represented in a 10 × 8 mm field size. All maps are overlaid with radial circles at 2 mm intervals. CCT, central corneal thickness; Kmax, maximum keratometry
