Figures & data

Figure 1 OCT pachymetry and ETM demonstrating normal epithelial thickness OD but marked thinning centrally (red arrow) and thickening peripherally (black arrows) OS in a “doughnut” pattern consistent with KC.

Notes: and present a keratorefractive surgery candidate with frank KC as observed by concordant abnormal findings on both ETM and Tomography.
