Abstract

UN PROCEDIMIENTO PARA EL TRATAMIENTO DE UNA LENTE DE CONTACTO BLANDA, A FIN DE AUMENTAR SU RESISTENCIA A LA DEPOSICION SOBRE ELLA, Y A LA DIFUSION Y ACUMULACION DENTRO DE ELLA, DE SUSTANCIAS QUE FAVOREZCAN SU ENTURBIAMIENTO Y DESCOLORACION DURANTE EL USO, Y PARA MEJORAR SU RESISTENCIA MECANICA, INCLUYE TRATAR UNA LENTE DE CONTACTO BLANDO, O REPLICA DE LENTE DE CONTACTO BLANDA, DE ESTER ACRILICO QUE CONTIENE GRUPOS HIDROXILO, CON UN ANHIDRIDO DE ACIDO ORGANICO DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA TRATAR AL MENOS UNA PORCION DE LAS MOLECULAS DEL POLIMERO SOBRE LAS SUPERFICIES EXTERIORES, POR EJEMPLO ESTERIFICANDO GRUPOS HIDROXILO SOBRE LAS MOLECULAS Y FACILITANDO LA EXTRACCION DE IMPUREZAS DE TIPO ORGANICO. EL PROCEDIMIENTO SE REALIZA OPCIONALMENTE EN PRESENCIA DE UN MEDIO QUE HINCHA PARCIALMENTE LAS REGIONES SUPERFICIALES DE LA LENTE O REPLICA ANTES DEL PROCESO O DURANTE EL MISMO.
