Abstract
Esta invención se refiere a un método para fabricar un lente de contacto que tenga una primera sección formada de un primer material y una segunda sección formada de un segundo material. El método incluye el uso de un molde de vaciado que tiene una pared extrema que se puede desplazar dentro del espacio definido dentro del molde para definir un pozo de recepción en donde el material puede vaciarse para ser curado/polimerizado y formar un botón de lente. El método incluye además: vaciar un primer material monómero en el pozo de recepción del molde y polimerizar/curar el material monómero; maquinar el artículo formado por el vaciado anterior hasta formar un lente de contacto, en donde el primer material monómero incluye un material polimerizable que tiene una acción similar a la penetración con respecto al material del cual se forma el molde del vaciado que actúa para unir el molde y el material polimerizado/curado.
