Patent

CA 2641327

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 pour corriger des aberrations optiques afin de modifier une courbure relative de champ en proposant des appareils oculaires, des systèmes et des procédés comprenant un facteur de correction prédéterminé pour produire au moins un stimulus sensiblement correcteur pour repositionner des points focaux périphériques, désaxés, par rapport au point focal central, dans l'axe ou axial tout en conservant le positionnement du point focal central, dans l'axe ou axial sur la rétine. L'invention peut être utilisée pour obtenir des images visuelles continues, utiles, nettes tout en retardant ou en diminuant en même temps la progression de la myopie ou de l'hypermétropie.
