Abstract
An intraocular lens includes an optic for focusing light and a movement assembly coupled to the optic. The movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic. The movement assembly includes a plurality of movement members each with a proximal region coupled to the optic and an enlarged distal region. The enlarged distal region may be integral with the proximal region, or may be mechanically coupled thereto.
Claims24
An intraocular lens comprising:
- an optic adapted to focus light to a retina of an eye and having a central optical axis;
- a movement assembly coupled to the optic and adapted to cooperate with the eye to effect accommodating movement of the optic;
- the movement assembly including a plurality of movement members each having a proximal region coupled to the optic and an enlarged distal region;
- and
- each of the enlarged distal regions is formed separately from and mechanically coupled to the proximal region of that movement member, and has a contact surface adapted to be in contact with a peripheral region of a capsular bag of an eye.
