The schematic model eye was developed from the position and curvature of the refractive surfaces of the rat eye. The cornea was treated as a single refracting surface, while the index of refraction of the crystalline lens was considered to be homogenous. Measured values included in the schematic model and table: ACD, LT, VCD, AL, and K. Indices of refraction (italicized numbers) were based on previous studies by Hughes.3
