Abstract

La presente se refiere a un proceso que comprende los pasos de hacer reaccionar una mezcla reactiva que comprende al menos un componente que contiene silicona, al menos un componente hidrofílico, y al menos un diluyente para formar un dispositivo oftálmico que posee un ángulo de contacto de avance de menos de aproximadamente 80s; y poner en contacto el dispositivo oftálmico con una solucion de extraccion acuosa a una temperatura de extraccion elevada, en donde al menos dicho diluyente posee un punto de ebullicion al menos aproximadamente 10° mayor que dicha temperatura de extraccion.
