  • Equipment for the correction of astygmatism by remodelling the corneal surface by means of photo-ablation
    Patent number: 5356409
    Abstract: The invention relates to equipment for the correction of astygmatism by modelling of the corneal surface by means of photo-ablation. A laser beam produced by an excimer laser is used, which is masked by a special mask (1) in such a way that, at each application, a pre-established surface of the cornea (3) is struck, from which cornea (3) a very thin uniform layer of tissue is removed.

  • Equipment for the correction of presbyopia by remodelling the corneal surface by means of photo-ablation
    Patent number: 5314422
    Abstract: 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.
