Distribution of Young's Modulus in Porcine Corneas after Riboflavin/UVA-Induced Collagen Cross-Linking as Measured by Atomic Force Microscopy
Figure 4
Depth of the CXL zone and corneal thickness.
Pachymetry readings were executed centrally on every sectioned specimen using the optical unit of the atomic force microscope. A) Mean stromal depth of the CXL zone for the PBS group, the DRY group, and the combined groups. B) Mean corneal thickness at the location of the profile measurement for the PBS group, the DRY group, and the combined groups. No significant difference in corneal thickness was found with respect to preparation type or cross-linking status. Error bars indicate the standard deviation.
