case_images: Pentacam images demonstrating the preoperative (a, b) and postoperative (c, d) corneal tomography in the right and left eyes, respectively. Severe flattening is observed after combined CXL and PRK (CXL Plus).

case_images: The preoperative minimum corneal thickness measured by the Pentacam-Scheimpflug imaging system (Oculus, Wetzlar, Germany) was 578 mum in the right eye and 560 mum in the left eye (Kmax was 49.5, and mean K was 45.9 in the right eye, and 48.5 and 45.5 in the left eye, respectively). The preoperative Pentacam scan revealed superior steepening in the front axial curvature map of both eyes (Fig. 1a, b). Corneal topography of both eyes revealed irregular flattening of the central cornea (Fig. 1b). The Pentacam scan of both eyes showed corneal flattening (38.00/40.60, Kmax was 49.1, and mean K was 33.5 in the right eye; 30.10/37.70, Kmax was 56.8, and mean K was 39.3 in the left eye) and thinning (thinnest point 227 mum in the right eye, 244 mum in the left eye) (Fig. 1c, d).
case_images: Photo-slit images of the right eye (a) and the left eye (b) demonstrate corneal haziness in the central zone is more dominant in the left eye. Anterior segment optical coherence tomography of the right eye in the horizontal plane (c) and vertical plane (d) demonstrates full-thickness stromal haze in a thin cornea.

case_images: During the slit lamp examination and anterior segment optical coherence tomography (Optovue, Inc., Freemont, CA, USA), central mid to deep stromal haziness (grade 2-3) was observed in both eyes (Figure 2a, b).
