Abstract

UN APARATO Y METODO PARA DIRIGIR ELECTRONES ACELERADOS HACIA AL MENOS UNA PARTE DE UNA SUPERFICIE DE UNA PIEZA DE MOLDE OFTALMICA ANTES DE RELLENAR CON MONOMERO Y POLIMERIZACION DE LA LENTE. EN PARTICULAR SE HA DESCUBIERTO QUE LA GENERACION DEL OXIGENO IONIZADA MEDIANTE UN ELECTRODO DE TRATAMIENTO DE EFECTO CORONA AUMENTA SIGNIFICATIVAMENTE LA ADHERENCIA DEL POLIMERO A LA PIEZA DE MOLDE ASI TRATADA. EN LA REALIZACION PREFERIDA, EL REBORDE ALREDEDOR DE LA PIEZA MACHO CONVEXA DEL MOLDE DE LENTE SE TRATA CON EFECTO CORONA DE MANERA QUE CUANDO LAS PIEZAS DE MOLDE SE SEPARAN DESPUES DE LA POLIMERIZACION DE LENTE. LA BANDA PARA JUNTA DE MATERIAL POLIMERIZADO EN EXCESO QUE RODEA LA CAVIDAD DE LA LENTE SE ADHIERE A ESTE REBORDE DE PIEZA MACHO CONVEXA MIENTRAS QUE LA LENTE SE RETIRA CON LA PIEZA CONCAVA HEMBRA.
