PROCESS TO DETERMINE THE SHAPE OF AN OPHTALMIC CORRECTION LENS FOR CORRECTING OPTICAL ABERRATIONS OF THE EYE BEYOND DEFOCUSSING OR ASTIGMATISM, AND IMPLEMENTATION DEVICE FOR SAID PROCESS

摘要

the method is as follows:a step for measuring the topography of the cornea of the eye to correct.the step of determining the shape of the posterior aspect of thelens from the measured corneal topography for athe mechanical behavior of the lens when the set is onthe eye.a step for measuring optical aberrations of the eye to correct.the step of determining the shape of the anterior surface of thecontact lens for correcting aberrations, based on the measurement of aberrationsthe eye to correct optical combined with data on the formcommitted to the posterior surface of the lens.the system includes units for measuring the topography and thethe aberrations of the eye, and an electronic unit for calculation.
