Patent

CA 2545390

A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing ocular apparatuses, systems and methods comprising a predetermined corrective factor to produce at least one substantially corrective stimulus for repositioning peripheral, off-axis, focal points relative to the central, on-axis or axial focal point while maintaining the positioning of the central, on-axis or axial focal point on the retina. The invention will be used to provide continuous, useful clear visual images while simultaneously retarding or abating the progression of myopia or hypermetropia.

L'invention concerne un procédé et un appareil de correction des aberrations optiques afin de modifier la courbure relative de champ à l'aide d'appareils, de systèmes et de procédés oculaires faisant appel à un facteur de correction prédéterminé pour produire au moins un stimulus sensiblement correcteur pour le repositionnement de points focaux, en dehors de l'axe, périphériques, relativement au point focal dans l'axe ou axial, central, tout en conservant le positionnement du point focal dans l'axe ou axial, central, sur la rétine. L'invention peut être utilisée pour obtenir des images visuelles claires, utiles, continues, tout en retardant ou en diminuant simultanément la progression de la myopie ou de l'hypermétropie.
