case_images: Top: axial/sagittal topography map showing central corneal steepening after inlay implantation. Kmax value is boxed in red. Bottom: corneal densitometry (CD) at 36 months postoperatively showing a slight ring of corneal opacity at the inlay periphery (arrow), and the CD value in red.

case_images: In topography, central corneal steepening was shown immediately after implantation and was stable at all visits using the axial/sagittal map display (Fig. 1, top). The CD value was stable at 17.2 GSU (Fig. 1, bottom).

case_images: Two months later, the patient returned with decreased UDVA (20/50) associated with a slight myopic shift of -0.25 D; the slit lamp examination showed central corneal haze progression, now encroaching toward the center of the inlay and topography showed a steepening at the inlay interface (Fig. 2), with further increase in Kmax by another +1.2 D.
case_images: Top: corneal densitometry (CD) showing central corneal haze and increased densitometry values in the 0- to 2-mm zone with CD value in red. Bottom: regressed values after steroid treatment with CD value in red.

case_images: The CD value also increased to 23.0 GSU (Fig. 3, top). The slit lamp examination showed minimal haze at the center of the inlay and the CD value decreased to 19.3 (Fig. 3, bottom).
