Fig. 4. Collagen Autofluorescence after 1 and 3 months.

Fig. 4.

The image in A is a CAF image taken within the central region of a one month sample. The average intensity increase in these samples was 1267 ± 181. The depth of crosslinking, measured by depth of increased intensity and demonstrated with an arrow in the image, was found to be 42.4 ± 3.4% of the total stromal thickness on average at one month. The image in B shows the corresponding CAF image for the three month samples. CAF intensity and depth remained constant between the two time points with values of 1224 ± 158 and 47.7 ± 7.6% at three months.
