A method and system are provided for eroding or ablating a shaped volume of an eye's corneal tissue (10) in accordance with the treatment of a specified eye condition. To determine the laser beam shot pattern, a plurality of laser beam shots of uniform intensity are first selected to form a uniform shot pattern of uniform shot density. The laser beam shots applied in accordance with the uniform shot pattern of uniform shot density would be capable of eroding a volume of the corneal tissue (10) of uniform height. The volume of uniform height is approximately equivalent to that of the shaped volume the laser beam shots are applied to the corneal tissue in a spatially distributed pattern spread over an area approximately equivalent to the surface area of the shaped volume to be eroded. The spatially distributed pattern extends the uniform shot pattern in fixed angles from a reference position on the shaped volume representative of the shaped volume's axis of symmetry. Shot density for the laser beam shots changes in correspondence with distance from the reference position.

Procédé et système d'érosion et d'ablation d'un volume tracé du tissu cornéen (10) de l'oeil dans le cadre du traitement d'un état particulier de l'oeil. Pour déterminer la répartition des impacts du faisceau laser, on sélectionne tout d'abord d'une série d'impacts d'intensité uniforme constituant une configuration uniforme d'impacts de densité uniforme où les coups du laser érodent un volume de tissu cornéen (10) de hauteur uniforme qui correspond sensiblement à celui du volume tracé. Les impacts du laser sont appliqués au tissu cornéen selon une répartition spatiale sur une zone sensiblement équivalente à l'aire de surface du volume tracé à éroder. Ladite répartition spatiale étend la configuration des impacts uniformes selon des angles déterminés à partir d'une position de référence représentative de l'axe de symétrie du volume tracé, la densité des impacts laser variant en fonction de leur distance par rapport à ladite position de référence.
