Abstract: In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.

Abstract: Un sistema (10) para realizar un seguimiento del movimiento de un ojo, que comprende: un sistema de cámara (22) configurado para generar una pluralidad de imágenes (34) del ojo; un sistema informático que comprende: una memoria (30) configurada para almacenar la pluralidad de imágenes y almacenar al menos una de las imágenes (34a) como una imagen de referencia; y uno o más procesadores (32) configurados para: realizar un seguimiento del movimiento del ojo dentro de un rango de seguimiento mediante la comparación de una imagen actualizada de la pluralidad de imágenes con la imagen de referencia, y mediante la determinación de un movimiento del ojo a partir de la comparación de la imagen actualizada y la imagen de referencia, teniendo el rango de seguimiento uno o más puntos de alerta; y determinar una orientación del ojo con relación a, al menos, un punto de alerta del rango de seguimiento, caracterizado por un dispositivo de salida (26) configurado para crear un indicador de rango (40, 42, 44, 46) que indica la orientación del ojo con relación al o a los puntos de alerta (41) del rango de seguimiento.

Abstract: A method for performing multi-level eye registration comprising: obtaining a first initial reference eye image by a first diagnostic device and defining a reference coordinate system; obtaining a second eye image by a surgery device, said second eye image being obtained in a pre-surgery phase before the surgery has started; performing a first registration between said first eye image and said second eye image to obtain a first registration result; obtaining a third eye image by said surgery device, said third eye image being obtained after surgery has started; performing a second registration between said second eye image and said third eye image to obtain a second registration result; combining said first and second registration results to obtain a combined registration result to thereby obtain a registration between said initial reference eye image obtained by said diagnostic device and said third eye image obtained by said surgery device after surgery has started.
