Abstract
Dispositivo de medida objetiva de la mejora en la calidad óptica del ojo. La invención consiste en un dispositivo de medida de la mejora en la calidad óptica del ojo caracterizado porque esta se determina de forma totalmente objetiva a través de la medida de la calidad de la imagen retiniana antes y después del proceso de mejora. El dispositivo comprende una fuente puntual (Fig. 1, 0) producida por un haz láser acoplado a una fibra óptica (Fig. 1, 9), cuya imagen (Fig. 1, 0'') se forma sobre la retina del ojo. La luz reflejada por la retina es registrada mediante una cámara CCD (Fig. 1, 1), donde se forma una imagen aérea (Fig. 1, O''`) de la imagen retiniana. La señal captada por el CCD es registrada por un ordenador (Fig. 1, 20) y procesada para evaluar de forma objetiva la calidad óptica del ojo.Device for objective measurement of the improvement in the optical quality of the eye. The invention consists of a device for measuring the improvement in the optical quality of the eye, characterized in that this is determined in a completely objective manner by measuring the quality of the retinal image before and after the improvement process. The device comprises a point source (Fig. 1, 0) produced by a laser beam coupled to an optical fiber (Fig. 1, 9), whose image (Fig. 1, 0'') is formed on the retina of the eye. The light reflected from the retina is recorded by a CCD camera (Fig. 1, 1), where an aerial image (Fig. 1, O''`) of the retinal image is formed. The signal captured by the CCD is recorded by a computer (Fig. 1, 20) and processed to objectively assess the optical quality of the eye.
