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.
Claims45
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 having a first stiffness;
- and
- a movement assembly coupled to the optic and adapted to cooperate with the eye to provide effective accommodating movement of the optic, at least a portion of the movement assembly being made of a second material having a second stiffness, wherein the first stiffness is greater than the second stiffness.
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.
A method of producing an accommodating intraocular lens comprising:
- shaping a composite member into an accommodating intraocular lens having an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the optic and adapted to cooperate with the eye to provide effective accommodating movement of the optic, at least a portion of the optic being made of a first material and at least a portion of the movement assembly being made of a second material, the first material being stiffer than the second material, the composite member including a central region including the first material and a peripheral region, coupled to the central region, including the second material, whereby the differential stiffness values create a hinge means effective for relative movement of the optic.
A method of producing an accommodating intraocular lens comprising:
- shaping a composite member into an accommodating intraocular lens having an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the optic and adapted to cooperate with the eye to provide effective accommodating movement of the optic, at least a portion of the optic being made of a first material and at least a portion of the movement assembly being made of a second material, the second material being more resilient than the first material, the composite member including a central region including the first material and a peripheral region, coupled to the central region, including the second material.
