System (10, 40) and method of photoaltering a region of an eye using an enhanced contrast between the iris and the pupil of the imaged eye. The system includes a laser assembly (14, 16, 20, 26, 28) outputting a pulsed laser beam, a user interface (32, 34) displaying one of a first digital image of the eye and a second digital image of the eye, and a controller (22) coupled to the laser assembly and the user interface. The first digital image has a first contrast between the pupil and the iris, and the second digital image has a second contrast between the pupil and the iris. The controller selectively increases the first contrast between the pupil and the iris to the second contrast between the pupil and the iris and directs the pulsed laser beam to the region of the eye based on one of the first and second digital images.
Linvention concerne un système (10, 40) et un procédé de photomodification dune région dun il utilisant un contraste amplifié entre liris et la pupille de lil imagé. Le système comprend un ensemble laser (14, 16, 20, 26, 28) fournissant en sortie un faisceau laser pulsé, une interface utilisateur (32, 34) affichant lune parmi une première image numérique de lil et une seconde image numérique de lil, et une unité de commande (22) couplée à lensemble laser et à linterface utilisateur. La première image numérique a un premier contraste entre la pupille et liris, et la seconde image numérique a un second contraste entre la pupille et liris. Lunité de commande augmente sélectivement le premier contraste entre la pupille et liris et le second contraste entre la pupille et liris et dirige le faisceau laser pulsé vers la région de lil en se basant sur lune parmi la première et la seconde image numérique.
