Structural model for emmetropic and myopic eyes

Abstract

A structural model for the eye was tested using refractive component data for 42 emmetropic eyes (-0.50 to +1.50 D) and 42 eyes having from 5.00 to 7.00 D of myopia. Parameter estimates derived by applying the structural model to emmetropic eyes and to myopic eyes demonstrated that a common model described the two types of eyes, but that emmetropic eyes and myopic eyes could be considered to belong to statistically discrete populations. Corneal radius and vitreous chamber depth were the most important components determining refractive state.
