Abstract

EN UN PROCEDIMIENTO PARA LA ELABORACION DE LENTES DE CONTACTO SE SUMINISTRA UN MATERIAL DE LENTE DE CONTACTO POLIMERIZABLE EN UNA MITAD (1) DE MOLDE Y A CONTINUACION SE CIERRA EL MOLDE POR MEDIO DE LA SEGUNDA MITAD (2) DE MOLDE. EL MATERIAL QUE SE ENCUENTRA ENTRE AMBAS MITADES DE MOLDE, EN LA CAVIDAD (12) FORMADA ENTRE ELLAS, SE POLIMERIZA A CONTINUACION CONFORMANDOSE CON ELLO UNA LENTE (CL) DE CONTACTO AUN NO HIDRATADA. LAS SUPERFICIES DADAS POR EL MOLDE A PARTIR DE UNA DE AMBAS MITADES (1,2) DE MOLDE SE TRATA PREVIAMENTE ANTES DE SU UTILIZACION EN UNA ZONA (20) FUERA DE LA ZONA ACTIVA OPTICAMENTE DE LA LENTE (CL) DE CONTACTO, DE TAL MODO QUE EN LA ABERTURA DEL MOLDE LA LENTE (CL) DE CONTACTO SE ADHIERE A LA MITAD DEL MOLDE PREVIAMENTE TRATADA.
