Abstract
Procedimiento para la obtención de lentes de contacto del tipo hidrogel, conformadas en una configuración cóncava-convexa, adaptándose sustancialmente la superficie cóncava a la córnea del ojo, caracterizado porque comprende polimerizar una mezcla que consiste esencialmente en: (A) un compuesto N-vinílico heterocíclico polimerizable que contiene al menos un átomo de nitrógeno en el anillo y una función carbonilo adyacente a un nitrógeno del anillo heterocíclico; y (B) una mezcla polimerizable que consiste esencialmente en: (1) monoéster polimerizable de un ácido elegido entre ácido acrílico y ácido metacrílico y mezclas de los mismos; y un alcohol polihídrico; (2) ésteres monoetilénicamente insaturados elegidos entre acrilato de alquilo, metacrilatos de alquilo, ésteres vinílicos de ácidos monocarboxílicos saturados de hasta 22 átomos de carbono y mezclas de los mismos; en donde el grupo alquilo del metacrilato o acrilato contiene de 1 a 22 átomos de carbono; (3) divinilbenceno y/o diviniltolueno; en donde las cantidades relativas de (A), (B) (1), (B)(2) y (B)(3), son de un 5 a un 40% en peso de (A), de un 93''8 a un 51,8% en peso de (B)(1), de un 1 a un 6% en peso de (B)(2), y de un 0,2 a un 2,2% en peso de (B)(3), basado en el peso total de (A), (B)(1), (B)(2) y (B)(3) empleados.
