Abstract:
A method of determining the shape of an ophthalmic contact lens for correcting optical aberrations of an eye, which method includes the steps of:measuring the optical aberrations of the eye to be corrected, and determining the shape of the front face of said lens from the measured optical aberrations of the eye to be corrected in order to correct said aberrations, measuring the topography of the cornea of the eye to be corrected, and determining the shape of the rear face of the lens from the measured topography of the cornea in order to limit the generation of unwanted aberrations when the lens is placed on the eye, and in which method, to determine the shape of the front face of the lens, data relating to the shape determined for the rear face of the lens is combined with the measured optical aberrations of the eye.
