The invention relates to a ring ( ) 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 ( ) extending between a first end ( ) and a point B, and a second branch ( ) extending between said point B and a second end ( ), 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 O 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&prime; and of radius R&prime;, where R<R&prime;<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.
