More Information
Summary:Disclosed is a method for determining the position of the eye rotation center of a subject's eye including: providing a geometric model of an eye, the eye being modeled with one sphere for the sclera and one ellipsoid for the cornea of the eye, the position of the eye rotation center being the distance between a center of the sclera and an apex of the cornea and being determined based on a set of personal parameters including a first geometric dimension of the eye, each personal parameter distinct from the position of the eye rotation center; determining a value of each personal parameter; and determining a first approximate value of eye position rotation center based on the geometric model using the personal parameters. Also disclosed is a method for calculating a personalized ophthalmic lens for the eye using such center, as well as a device implementing this method.
