Figure 8. The difference between the transmittance of the control corneas and that of the cross-linked corneas of three rabbits (#6, #9, and #11) and the other seven rabbits. The solid line represents those whose corneal thickness differences were less than 7 µm (#6, #9, and #11), and the dashed line represents the remaining rabbits. The transmittance difference of the three rabbits was 3%–4% less than the others, but the overall pattern was similar between the groups.
