Optical evaluation of decellularized and gamma irradiated porcine corneas. (A) Light transmission through the native human cornea (NHC), native porcine cornea (NPC), decellularized porcine cornea (DPC) and gamma irradiated decellularized porcine cornea (G-DPC); from UV to visual wavelengths. (B) Macro pictures of porcine corneas after different treatments placed on a black-white stripe pattern projected on a self-illuminated screen. (C) Intensity (conventional OCT) and birefringence (PS-OCT) images of the intact porcine cornea before extraction from the eye globe (intact NPC), together with native and treated corneas. The color bar of the birefringence images displays a range of refractive index contrast from 0 to 0.0022. The birefringence values were only plotted in areas with a sufficiently high degree of polarization.
