Abstract
Se describen sistemas y metodos para producir lentes de contacto a base de hidrogel de silicona. Ciertos de los presentes sistemas incluyen una estacion para forma moldes de lentes de contacto, una estacion para llenar una seccion de molde de lente de contacto con una composicion precursora de lente y para colocar una segunda seccion de molde en la seccion de molde relleno para formar un montaje de molde lente de contacto, una estacion de curado para formar un lente de contacto, una estacion de separacion de montaje de molde y una estacion de extraccion/hidratacion. Ciertos de los presentes metodos incluyen formar una pluralidad de secciones de molde, coloca una composicion precursora de lente en una superficie de una primera seccion de molde, colocar una segunda seccion de molde en la primera seccion de molde, polimerizar la composicion precursora de lente, separar la primera y segunda secciones de molde, retiraron el lente de contacto a base de hidrogel de silicona de una de las secciones de molde, extraer los componentes extraibles del lente de contacto e hidratar el lente de contacto.
