Her slit-lamp examination revealed eight well-healed RK scars in the right eye, nearly at 90% corneal thickness, and 10 similar incisions in the left eye of two had separated wound lips in the temporal part (Figs. 1a, 2a, b). The thinnest point pachymetry of the right eye was 397micro and the maximum keratometric power (P-Kmax) was 50.1 diopter (D) (Fig. 1a) (Table 2). The thinnest point pachymetry of the left eye was 382micro, and the maximum keratometric power (P-Kmax) was 52.1 D (Fig. 1b) (Table 2).

Her slit-lamp examination revealed eight well-healed RK scars in the right eye, nearly at 90% corneal thickness, and 10 similar incisions in the left eye of two had separated wound lips in the temporal part (Figs. 1a, 2a, b). These values were similar to that of pre-CXL corneal topography (Fig. 2b).

However, there was a progress of inferotemporal corneal ectasia matching with separated wound lips in the slit lamp examination in the corneal topography of the left eye (Fig. 3a, b). Even though the thinnest point pachymetry of the left eye was similar to the pre-CXL value (395micro), the increase of P-Kmax (57.16 D) was remarkable (Fig. 3c) (Table 2). Additionally, the anterior segment optic coherence tomography (AS-OCT) shows the separated wound lips (Fig. 3d, e).
