Abstract
(EN) The invention relates to a lens that can be implemented both as a contact lens and as an intraocular lens, the thickness of the lens being in both cases obtained by an iteration process and being dependent on an aperiodic and ordered staircase function Gs(u), where S is the number of iterations and is equal to or lower than 2. The contact lens is used in the control of myopia. The lens production method starts from a given refractive lens and includes modifying the surface of the lens by means of the staircase function Gs(u), where S is equal to or lower than 2.
(ES) La lente puede implementarse tanto en la forma de una lente de contacto como en la forma de un lente intraocular, y en ambos casos su espesor depende de una función escalonada Gs(u), aperiódica y ordenada mediante un proceso iterativo, donde S es el número de iteraciones y es igual o inferior a 2. El uso de la lente de contacto es para el control de la miopía. El procedimiento de obtención de la lente parte de una lente refractiva dada y comprende modificar la superficie de la misma mediante la función escalonada Gs(u), para un valor de S igual o inferior a 2.
(FR) L'invention concerne une lentille pouvant être mise en oeuvre aussi bien sous la forme d'une lentille de contact que sous la forme d'une lentille intra-oculaire, et dans les deux cas son épaisseur dépend d'une fonction échelonnée Gs(u), apériodique et ordonnée par un processus itératif, où S représente le nombre d'itérations et est égal ou inférieur à 2. La lentille de contact a une utilité dans le contrôle de la myopie. L'invention concerne le procédé d'obtention de la lentille faisant partie d'une lentille réfractive donnée et consiste à modifier la surface de cette-dernière par la fonction échelonnée Gs(u), pour une valeur de S égale ou inférieure à 2.
