Abstract:
A capsular bag ring to be implanted within the capsular bag of an eye, the capsular bag denoting a circle having a center O, a radius R and a tangential point A, said ring comprising an elongate element forming two asymmetrical branches having different radii of curvature, each branch of said element beginning at a connection point B and terminating in first and second ends respectively, each of said end having handling means,a first branch extending between said first end and said connection point B, and a second branch extending between said point B and said second end, said branches of said element lying in a plane and having a thickness that is constant in a direction that is orthogonal to said plane and said element having inner and outer edges, said elongate element having a length greater than the perimeter of said circle of said capsular bag and said outer edge of said first branch defining a portion of a circle of the center Oâ€² and radius Râ€², where Ra length of any segment joining the center O to a point Mâ€² of the outer edge of the second branch is greater than the length of a corresponding segment joining the center O of the circle to a point Mâ€² of the outer edge of the first branch, the point M being such that the angle between the segment OM and a median diameter joining the center O to a tangential point A is equal to the angle between the segment OMâ€² and said median diameter; and wherein the radius of curvature at a point Mâ€² of the outer edge of the second branch is greater than the Râ€².
