Abstract:
Device for treating presbyopia or other ocular disorder related to an eye accommodation defect, characterized in that it comprises a piece having substantially the shape of at least a ring portion having the general shape of a truncated cone with an axis of revolution and a first edge disposed on a circle of diameter D1 included between 12.5 and 13.5 mm and a second edge disposed on a circle of diameter D2 included between 9.5 and 10.5 mm, said edges being offset in the direction of said axis of revolution by a length h included between 0.5 and 2.5 mm, said first edge being designed to rest, over at least part of its length, on part of the internal wall of the eye and said second edge being capable of being pressed against a median zone of the zonules of the crystalline lens, said first and second edges being joined together by a central part which presents a sufficient mechanical strength for the second edge to provoke a displacement of said median zone of said zonules stressing them and enabling them to cause the deformation of the crystalline lens under the effect of stimulations applied to said zonules.
