Abstract
An accommodating IOL comprises an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the eye to provide effective accommodating movement, preferably axial movement, of the optic. At least a portion of the movement assembly is made from a material that is less stiff and/or more resilient than the material used to make the optic. Optionally, an outer ring or support portion made at least partially from either a relatively stiff material such as the material used in the optic or a relatively resilient material such as the material used in the movement assembly is also provided.
Claims14
An intraocular lens comprising:
- an optic adapted to focus light toward a retina of an eye, at least a portion of the optic being made of a first material;
- and
- a movement assembly coupled to the optic and adapted to cooperate with the eye to provide effective accommodating movement of the optic in response to action of the eye, at least a portion of the movement assembly being made of a second material that is more resilient than the first material,
- wherein the movement assembly comprises a pair of opposing fixation members and a pair of opposing enlarged support portions at distal portions of the pair of opposing fixation members, the pair of opposing enlarged support portions adapted to contact a capsular bag of the eye,
- wherein each fixation member of the pair of opposing fixation members decreases in width from a proximal end coupled to the optic to an intermediate portion, and increases in width from the intermediate portion to the distal portion, and
- wherein, for each fixation member, a hinge having a thickness less than the proximal portion and the distal portion is provided at a narrowest section of the intermediate portion.
