Abstract

SE DESCRIBE UN PROCEDIMIENTO Y DISPOSITIVO PARA LA CONFORMACION DE SUPERFICIES, EN PARTICULAR LENTES, POR MECANIZADO DE LAS MISMAS CON LASER, Y QUE SE UTILIZAN PREFERENTEMENTE PARA QUERATECTOMIA Y PARA LA CONFORMACION DE LENTES DE CONTACTO OFTALMOLOGICAMENTE EXACTAS. A FIN DE ASEGURAR UNA CORRECCION PARCIAL AL MENOS ACEPTABLE DE LA SUPERFICIE QUE DEBE MECANIZARSE DESPUES DE UNA INTERRUPCION REPENTINA DEL PROCESO DE MECANIZADO DE LA SUPERFICIE, EL DISPOSITIVO TIENE UN LASER PULSATIL DE EXPLORACION (1), UNA UNIDAD (2) DE CONFORMACION DEL RAYO Y UNA UNIDAD (3) DE DESVIACION DEL RAYO LASER, QUE HACE QUE EL RAYO SE DESVIE SOBRE LA SUPERFICIE (4) QUE DEBE MECANIZARSE. LA UNIDAD (3) DE DESVIACION DEL RAYO LASER Y LA UNIDAD (2) DE CONFORMACION DEL RAYO PUEDEN CONTROLARSE POR MEDIO DE UNA UNIDAD DE CONTROL (5), QUE TIENE UNAS UNIDADES DE ENTRADA QUE COOPERAN, PRIMERA (6) Y SEGUNDA (7), UNA UNIDAD DE CALCULO (8) A LA QUE SE SUMINISTRAN LOS DATOS PROCEDENTES DE LAS UNIDADES DE ENTRADA PRIMERA Y SEGUNDA (6; 7), UN GENERADOR DE BLOQUES (9) A LOS QUE SE SUMINISTRAN LOS DATOS PROCEDENTES DE LA UNIDAD DE CALCULO (8) Y EN LA QUE SE ASOCIAN MUTUAMENTE LAS COORDENADAS INDIVIDUALES DE MECANIZADO POR LASER PARA RETIRAR CUALQUIER CAPA INDIVIDUAL PREDETERMINADA DE LA SUPERFICIE, Y UN GENERADOR DE SECUENCIA (10) AL QUE SE SUMINISTRAN LOS DATOS GENERADOS POR EL GENERADOR DE BLOQUES (9), REUNIDOS EN BLOQUES QUE CORRESPONDEN A UNA ZONA INDIVIDUAL DE MECANIZADO, Y QUE ORDENA CADA BLOQUE INDIVIDUAL SIGUIENDO UNA SECUENCIA PREDETERMINADA. UNA SECUENCIA PARTICULAR DE BLOQUES TRANSMITIDOS POR EL GENERADOR DE SECUENCIA (10) ACTUA SOBRE LA UNIDAD (3) DE DESVIACION DEL RAYO LASER Y LA UNIDAD (2) DE CONFORMACION DEL RAYO, DE MANERA QUE SE ASEGURE UNA COMPLETA CORRECCION PARCIAL DE LA SUPERFICIE (4) QUE DEBE MECANIZARSE PARA CADA SECUENCIA DE BLOQUES. TAMBIEN SE PROPORCIONA UNA UNIDAD CENTRAL DE PROCESO (11) QUE COORDINA DE MANERA PREDETERMINADA LA CONMUTACION Y EL CONTROL DE AL MENOS LA UNIDAD LASER (1), LA UNIDAD DE CONFORMACION DEL RAYO (2; 21) Y LA UNIDAD DE DESVIACION DEL RAYO LASER (3), SEGUN LOS DATOS DE CONTROL PROCEDENTES DE LA UNIDAD DE CONTROL (5).
