The Kmax, K1, K2, CCT and TCT values measured before and at 1, 3, 6 and 12 months after ATE-CXL. The asterisk indicates a significant difference (P < 0.05) that was detected when compared with the preoperative value. (Kmax, the maximum keratometry; K1, steepest meridian keratometry; K2, flattest meridian keratometry; CCT, central corneal thickness; TCT, thinnest corneal thickness; ATE-CXL, accelerated transepithelial corneal cross-linking)
