Figure 5.
Absorption/transmission spectra of porcine cornea cross-linked with aliphatic β-nitro alcohols. Samples were cross-linked, as described in the Figure 2 legend, with the use of 10 mM β-nitro alcohols for 96 hours. Changes in light absorption/transmission were studied with a fiber-optic spectrometer. (A) Raw absorption data (black) are corrected for light scatter. Small dotted line: scatter correction (y = axb). Dashed line: corrected absorption curve. Arrow: calculated transmission curve, also indicated by the accompanying formula. (B) Examples of corrected absorption and transmission curves for the three β-nitro alcohols studied. The greatest effects were seen using 2ne, followed by 2nprop and 3n2pent.
