Abstract
Esta invencion incluye métodos y sistemas para procesar lentes de hidrogel utilizando soluciones acuosas como auxiliares de la lixiviacion. Reivindicacion 1: Un método para eliminar componentes y diluyentes sin reaccionar de una lente oftálmica que comprende silicona, comprendiendo el método: exponer dicha lente oftálmica a una primera solucion acuosa que comprende aproximadamente 5% o más de un primer agente de lixiviacion que comprende uno o más de: E12E10, SDS, EH-5, PPG 425, EtOH, y IPA, y donde la primera solucion acuosa comprende adicionalmente 5% o más de un segundo agente de lixiviacion que comprende SCAW; calentar dicha primera solucion acuosa a la cual es expuesta la lente oftálmica; y enjuagar dicha lente oftálmica a través del contacto con una segunda solucion acuosa hasta que dicha lente comprende un nivel de componentes y diluyentes sin reaccionar que está por debajo de un umbral predeterminado.
