Case 1. (a, b) Axial curvature, pachimetry, and elevation maps of the corneal surface of both eyes obtained with Pentacam HR corneal tomography and (c) Belin/Ambrosio enhanced ectasia display (BAD) of the right eye and (d) the left eye.

Corneal topography (Pentacam; Oculus Optikgerate GmbH, Wetzlar, Germany) findings were compatible with corneal ectasia in the right eye and a postmyopic ablation pattern in the left eye (Fig. 1).
Case 1. (a) Tomographic and Biomechanical Index (TBI) assessment of the right eye and (b) the left eye, and (c) Corvis Biomechanical Index (CBI) display of the right eye and (d) the left eye.

CBI, TBI, and BAD-D values suggested biomechanical weakness (Fig. 2). Corneal crosslinking (CXL) was planned for the right eye.

Case 2. (a, b) Axial curvature, pachimetry, and elevation maps of the corneal surface of both eyes obtained with Pentacam HR corneal tomography and (c) Belin/Ambrosio enhanced ectasia display (BAD) of the right eye and (d) the left eye.

Pentacam corneal topography findings were consistent with corneal ectasia in the right eye and a postmyopic ablation pattern in the left eye (Fig. 3).
Case 2. (a) Tomographic and Biomechanical Index (TBI) assessment of the right eye and (b) the left eye.

Corvis ST revealed biomechanical weakness in both eyes (Fig. 4). CXL was planned for the right eye and the patient was warned about the possibility of ectasia development in the left eye.
