The invention relates to a ring (10) for a capsular bag, the ring being constituted by a curved elongate element presenting substantially constant thickness and having inner and outer edges. The elongate element comprises a first branch (30) extending between a first end (20) and a point B, and a second branch (32) extending between said point B and a second end (22), said outer edge of the elongate element when at rest and in its plane of symmetry being disposed substantially tangentially at a point A to a circle of center 0 and of radius R not less than the radius of the capsular bag, the outer edge of said first branch being defined by a portion of a circle of center O' and of radius R', where R < R' < 1.10R, the outer edge of the second branch of said elongate element being defined by a portion of a hyperbolic spiral of center O and connected tangentially to said portion of a circle at said point B.
L'invention concerne un anneau (10) pour sac capsulaire constitué par un élément allongé courbe présentant une épaisseur sensiblement constante et des bords externe et interne. L'élément allongé comporte une première branche (30) s'étendant entre une première extrémité (20) et un point B et une deuxième branche (32) s'étendant entre ledit point B et une deuxième extrémité (22), ledit bord externe de l'élément allongé, au repos et dans son plan de symétrie, est disposé sensiblement tangentiellement en un point A à un cercle de centre O et de rayon R au moins égal au rayon du sac capsulaire, le bord externe de ladite première branche étant défini par une portion de cercle de centre O', et de rayon R' (avec R < R' < R x 1,10), le bord externe de la deuxième branche dudit élément allongé étant défini par une portion de spirale hyperbolique de centre O et raccordée tangentiellement à ladite portion de cercle audit point B.
