MULTIFOCAL, HYBRID DIFFRACTIVE-REFRACTIVE OPHTHALMIC LENS, USE OF THE LENS AND METHOD FOR THE PRODUCTION THEREOF
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...

Summary: | 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.
Mejoras en el objeto de la patente principal nº 201031316 por "Lente oftálmica multifocal y procedimiento para su obtención". Las mejoras son relativas a la lente oftálmica multifocal híbrida difractiva-refractiva y al procedimiento para su obtención, en ambos casos cuando ésta es una lente de contacto, y se centran en que el número de iteraciones S para el proceso iterativo que ordena la función escalonada aperiódica Gs(u) es igual o inferior a 2, así como en el uso de la lente para el control de la miopía. |
