Effect of the corneal nano structure on light transmittance

We performed a theoretical analysis for corneal transparency by using a 3D simulator of FDTD (Finite Difference Time Domain) method. For that purpose, we examined light transmittance through detection of output light intensity with a simplified lattice model for the collagen fibrils in the corneal stroma. The geometrical nano-structure of the collagen fibrils in the corneal stroma is the main factor for light transparency of the cornea. Thus, we examined the effect of fibril diameter and lamellae staking angle on the light transparency of the cornea.
