Abstract

Un método para el revestimiento de artículos de hidrogely de hidrogel que contiene silicona, y los artículos preparados por el método, donde el revestimiento se aplica primero a la superficie moldeadora en la cual se curará un material formador del artículo para formar dicho artículo. El método permite que el espesor de uniformidad del revestimiento pueda ser más fácilmente controlado que en los métodos de revestimientos conocidos. Se describe también el método par la obtención de lentes de contacto .
