Abstract

PROCESO PARA LA FABRICACION DE UNA LENTE DE CONTACTO MOLDEADA QUE CONTIENE UNA ZONA VISUAL CENTRAL Y TRANSPARENTE CIRCUNSCRITA POR UN IRIS COLOREADO, QUE CONSISTE EN: (A) RECUBRIR CON UN LIQUIDO COLOREADO, QUE PUEDE SER ENDURECIBLE O TERMOPLASTICO, UN MOLDE PARA FABRICAR UNA LENTE DE CONTACTO, EN LA SUPERFICIE DE LA LENTE EN LA QUE ESTA FORMADO EL IRIS, PARA PRODUCIR UNA PELICULA COLOREADA QUE CONTIENE UNA SUPERFICIE EXPUESTA AL INTERIOR DEL MOLDE Y UNA SUPERFICIE EN CONTACTO CON EL MOLDE. (B) CARGAR EL MOLDE CON LA RESINA UTILIZADA PARA FORMAR EL CUERPO DE LA LENTE, A LA VEZ QUE SE MANTIENE LA PELICULA COLOREADA EN LA PARTE DE IRIS Y SE CONFIGURA LA RESINA ALREDEDOR DE LA PELICULA COLOREADA, FORMANDO LA SUPERFICIE DE LA PELICULA UNA SOLA PIEZA CON EL CUERPO DE LA LENTE Y LA SUPERFICIE DE LA PELICULA FORMA PARTE DE LA SUPERFICIE EXTEROR DE LA LENTE CUANDO LA LENTE MOLDEADA ES RETIRADA DEL MOLDE.
