A ring (13) is circular in shape, open-ended and of variable diameter, being made from a biocompatible material with a shape memory effect. The ring can be made from a supple layer grafted on the outer periphery of a hard ring, and its dimensions can be adjusted by a system of pulleys or interlocking teeth. A ring (13) is circular in shape, open-ended and of variable diameter, being made from a biocompatible material with a shape memory effect. It is designed to be inserted surgically into the zonules (12) of the ocular globe to compensate for a loss of tension in the zonule fibres resulting from an increase in the diameter of the lens (10), generally caused by ageing. The ring can be made from a supple layer grafted on the outer periphery of a hard ring, and its dimensions can be adjusted by a system of pulleys or interlocking teeth. |
