Abstract

El método comprende irradiar un haz de luz sobre un ojo, en donde dicho haz de luz previamente a su incidencia sobre dicho ojo pasa a través de un objeto opaco con unas zonas que dejan pasar la luz en un mayor o menor grado, de manera que sobre el ojo se recibe la luz en zonas diferenciadas claras y oscuras; capturar una serie de imágenes de Purkinje del ojo tras la reflexión del haz de luz en cada cambio de medio del ojo incluyendo las superficies de la córnea y las superficies del cristalino; y calcular la difusión intraocular asociada, de manera separada, a cada uno de los diferentes medios del ojo mediante el procesamiento de las imágenes de Purkinje capturadas realizando una medida de la distribución de la luz en dos o más de las imágenes de Purkinje.
