The invention concerns a device for treating presbyopia or other ocular disorders related to an eye accommodation defect. Said device (20) comprises a piece (22) having substantially the shape of at least a ring portion with an axis of revolution and first (22a) and second (22b) edges offset along radial directions and along the direction of said axis of revolution, said first edge (22a) being designed to rest, over at least part of its length, on part of the eye internal wall and said second part (22b) capable of being pressed against a median zone (18c) of zonules of the crystalline lens (18), whereby is obtained a displacement of the median zone of said zonules stressing them and enabling them to cause the deformation of the crystalline lens (14) under the effects of stimulation applied to said zonules.

L'invention concerne un dispositif pour traiter la presbytie ou autres affections oculaires liées à un défaut d'accommodation de l'oeil. Le dispositif (20) comprend une pièce (22) ayant sensiblement la forme d'au moins une portion d'anneau présentant un axe de révolution et un premier (22a) et un deuxième (22b) bord décalés selon des directions radiales et selon la direction dudit axe de révolution, ledit premier bord (22a) étant destiné à être en appui, par au moins une partie de sa longueur, sur une partie de la paroi interne de l'oeil et ledit deuxième bord (22b) étant apte à être appliqué contre une zone médiane (18c) des zonules (18) du cristallin, par quoi on obtient un déplacement de ladite zone médiane desdites zonules provoquant leur mise sous tension et les rendant aptes à provoquer la déformation du cristallin (14) sous l'effet de stimulations appliquées aux dites zonules.
