An artificial eye lens such as a contact lens or intra-ocular lens corrects astigmatism by two sets of substantially linear parallel zones arranged to diffract light predominantly into one order at one orientation, the spacing of the zones diminishing on either side of the linear axis. In addition circular diffraction zones may be provided to give both spherical and cylindrical power for astigmatism correction.

Un cristallin artificiel, comme une lentille cornéenne ou un cristallin intra-oculaire, corrige l'astigmatisme au moyen de deux séries de zones parallèles substantiellement linéaires disposées de façon à diffracter la lumière principalement dans un ordre à une orientation, l'espacement des zones diminuant de chaque côté de l'axe linaire. Des zones de diffraction circulaires peuvent aussi être fournies pour donner une puissance sphérique et cylindrique pour la correction de l'astigmatisme.
