<p>The invention relates to equipment for the correction of presbyopia by means of corneal surface modelling by photo-ablation, of the type which uses a laser beam (16) (excimer laser) which is masked with a special mask (5) in such a way as to strike surfaces (19) of the cornea (3) in a sickle-shape configuration and located in proximity to the lower area of the pupil rim (20), on which surfaces (19) a removal action of very small-thickness uniform tissue layers is effected. <IMAGE></p> |
