Abstract
METODO PARA LA FABRICACION DE UNA LENTE CORNEAL BIFOCAL DE INDICE DE REFRACCION UNIFORME. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE CORTA PRIMERAMENTE UNA SUPERFICIE EXTREMA DE UNA PIEZA BRUTA DE LENTE CILINDRICA EN UN TORNO, PARA FORMAR UNA SUPERFICIE CONCAVA INTERNA CENTRAL QUE HA DE AJUSTARSE A LA CORNEA DEL USUARIO; SEGUNDA, SE CORTA UNA SUPERFICIE CONCAVA INTERNA PERIFERICA QUE FORMA UN ANGULO PROTUBERANTE EN LA LINEA DE UNION CON LA SUPERFICIE PRIMERAMENTE CORTADA; TERCERA, SE CORTA EN UN TORNO CON UN ACCESORIO LENTICULAR, UNA SUPERFICIE CONVEXA EXTERIOR QUE DEFINE UN SEGMENTO DE VISION CERCANA Y UNA SUPERFICIE EXTERNA PERIFERICA DE CURVATURA MAS PLANA QUE FORMA UN ANGULO REENTRANTE EN LA LINEA DE UNION CON LA SUPERFICIE DEL SEGMENTO DE VISION CERCANA.
