Representative Brillouin results for the S-CXL group. (a) Distribution of Brillouin shifts in a LASIK-only eye. The distribution is depicted top down from the anterior to the posterior. (b) Distribution of Brillouin shifts in the same eye after CXL over the flap. According to Eq. (1), a higher Brillouin shift correlates to a larger longitudinal modulus. Increase of longitudinal modulus is elucidated with different colors. (c) Lateral averaged depth profiles of Brillouin shifts in (a) and (b).
