Abstract

SE PROPONEN METODOS Y SISTEMAS PARA EL REPERFILADO CORNEO UTILIZANDO UN HAZ ANGULAR DE RADIACION ABLATIVA PARA CORREGIR ERRORES DE REFRACCION DE LA VISION Y/O CREAR "ZONAS DE TRANSICION" QUE REDUZCAN CUALQUIER DISCONTINUIDAD EN LA SUPERFICIE DE LA CORNEA DESPUES DE PROCEDIMIENTOS PARA CORREGIR LA HIPERMETROPIA O EL ASTIGMATISMO. LOS METODOS Y SISTEMAS PROPUESTOS PUEDEN UTILIZARSE TAMBIEN PARA MODIFICAR LA DISTRIBUCION DE INTENSIDADES DEL HAZ LUMINOSO, DE MANERA QUE LA RADIACION ANULAR TENGA UNA INTENSIDAD VARIABLE DEPENDIENDO DEL RADIO Y, POR TANTO, CONSIGA UN EFECTO DE MEZCLA O CUALQUIER OTRO EFECTO DESEADO CON EL MENOR NUMERO DE PULSOS. SE PROPONEN METODOS DE QUERATECTOMIA FOTORREFRACTARIA (QFR), ENTRE ELLOS LOS PASOS NECESARIOS PARA (A) REPERFILAR SELECTIVAMENTE LA CORNEA ELIMINANDO TEJIDO CORNEO CON RADIACION ABLATIVA PARA FORMAR UNA REGION REPERFILADA EN LA ZONA OPTICA QUE AUMENTE, AL MENOS EN PARTE, LA CURVATURA CENTRAL DE LA CORNEA, Y (B) APLICAR A LA REGION PERIFERICA DE LA CORNEA UN HAZ ANULAR DE RADIACION ABLATIVA CON UNA INTENSIDAD QUE VARIE RADIALMENTE DESDE EL SEGMENTO INTERIOR AL EXTERIOR DEL HAZ ANULAR PARA CREAR UNA ZONA DE TRANSICION SUAVE ENTRE LA REGION REPERFILADA Y LA REGION INTACTA DE LA CORNEA. SE PROPONEN ELEMENTOS DE LENTE OPTICA CON UNA CARA ANTERIOR GENERALMENTE CONICA Y UNA CARA POSTERIOR QUE SUELE SER PERPENDICULAR AL RECORRIDO DEL HAZ INCIDENTE. LA LUZ QUE ATRAVIESA ESTE ELEMENTO OPTICO SE REFRACTARA EN UN HAZ ANULAR. EL PERFIL DE INTENSIDAD DEL HAZ ANULAR PUEDE MODIFICARSE UTILIZANDO UN HAZ INICIAL QUE NO TENGA UN PERFIL UNIFORME O VARIANDO LA FORMA DE LA CARA ANTERIOR O POSTERIOR DEL ELEMENTO OPTICO.
