Attempted versus achieved spherical equivalent refraction (SE) in keratoconic patients who underwent corneal collagen cross linking followed by Corneal-Wavefront guided transepithelial photorefractive keratectomy (TransPRK). Achieved SE correction showed a linear correlation with attempted SE correction (slope = 0.8178, intercept = −1.2213D and r2 = 0.1081) (Fig. 3), however with a wide distribution.
