Abstract

LA LENTE DE CONTACTO DESCRITA COMPRENDE UN SOLO MATERIAL POLIMERO O COPOLIMERO Y TIENE UNA ZONA OPTICA CENTRAL DE MAYOR RIGIDEZ QUE UNA ZONA CIRCUNDANTE CARENTE DE PROPIEDADES OPTICAS. LA RIGIDEZ DE LA ZONA OPTICA CENTRAL ES SUFICIENTE PARA QUE CONSERVE UN PERFIL CORRECTOR DE ASTIGMATISMO CUANDO LA LENTE ESTA APLICADA A UN OJO, MIENTRAS QUE LA ZONA CIRCUNDANTE CARENTE DE PROPIEDADES OPTICAS SE ADAPTA A LA CONFIGURACION DEL OJO. LA ZONA RIGIDA DE LA LENTE SE PRODUCE MEDIANTE UN PROCEDIMIENTO EN EL QUE SE HACE QUE LA ZONA CENTRAL LLEGUE A SER MAS RIGIDA QUE EL RESTO DE LA LENTE GRACIAS A UN PROCESO DE TRATAMIENTO QUIMICO TAL COMO EL DE ESTERIFICACION. LA LENTE DEL INVENTO ES ESPECIALMENTE UTIL PARA LA CORRECCION DEL ASTIGMATISMO.
