Figure 7. The difference between the transmittance of the control corneas and that of the cross-linked corneas from ten rabbits. The difference was 8.383% at 650 nm and increased as the wavelength decreased, reaching a maximum of 20.591% at 320 nm, and decreasing rapidly to 4.770% at 300 nm. Additionally, a local hump was found between 425 and 455 nm, and a focal maximum at 350 nm.
