Optical models of the human cornea and tear film typically employ a single homogeneous
cornea with an average refractive index. I propose to use a more realistic multilayer model …

The suggestion that the central cornea can be modeled as a uniaxial birefringent material
with its optic axis normal to the surface is explicitly tested by numerical calculations. A …

A model of the cornea's lamellar structure is proposed that is capable of explaining
experimental results obtained for the transmission of normal-incidence polarized light …

We consider a system of anisotropic layers as an optical model of the eye cornea. Effective
refraction indices for normally incident light are calculated with the assumption that each …

A novel model of human corneal birefringence is presented. The cornea is treated as a
homogeneous biaxial linear birefringent medium in which the values of the binormal axes …

The refractive index of the cornea and overlying tear film are key factors affecting refraction
and overall optical properties of the eye. A figure of 1.376 is often quoted for the refractive …

The refractive status of the posterior corneal surface has not been well studied. The purpose
of this study is to quantitatively evaluate the regular and irregular astigmatism of the …

Generally, the analysis of corneal topography involves fitting the raw data to a parametric
geometric model that includes a regular basis surface, plus some sort of polynomial …

To describe the human corneal surface, due the absence of complete topographical data,
mathematical models are required. The mathematical formula permits a relatively simple …

Cornea, lens and eye models are analyzed and compared to experimental findings to
assess properties and eventually unveil optical design principles involved in the structure …
