<p>The invention concerns a ring (10) for capsular bag formed by a curved elongated element having a substantially constant thickness and internal and external edges. The elongated 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 external edge of the elongated element, when inactive and in its plane of symmetry, is arranged substantially tangential in a point A to a circle with centre O and radius R at least equal to the radius of the capsular bag, the external edge of said first branch being defined by a portion of circle with centre O', and with radius R'( with R < R' < R x 1.10), the external edge of the second branch of said elongated element being defined by a hyperbolic spiral portion with centre O and tangentially connected to said circle portion at point B.</p> |
