Slit-lamp biomicroscopic examination showed posterior embryotoxon, iris hypoplasia, and iridocorneal adhesion in his both eyes, corectopia in the right eye, and peripheral inferior thinning and ectasia in the left eye (Figure 1(a) and (b)).
Anterior sagittal curvature map shows a slightly asymmetric bowtie pattern in the right eye (a) and a crab-claw pattern in the left eye (b). The bell sign was seen in the full coverage (12-mm) corneal thickness map in the left eye (b).

Anterior sagittal curvature map (Pentacam HR; Oculus) showed a slightly asymmetric bowtie pattern in the right eye and a crab-claw pattern in the left eye, and the bell sign was seen in the full coverage (12-mm) corneal thickness map in the left eye (Figure 2(a) and (b)).
Scheimpflug imaging shows the normal thickness of the right cornea (a) and the peripheral thinning of the left cornea (b).

Scheimpflug imaging of the patient also confirmed the peripheral thinning of the left cornea, while the right cornea was unremarkable (Figure 3(a) and (b)).

At the 28th month of follow-up, topographic evaluation showed 1.1-D flattening of Kmax and 88-microm decrease of thinnest corneal pachymetry (Figure 4) compared to preoperative topographic findings and CDVA improved to 20/20 with scleral lens (Figure 5).
