Abstract
Intraocular lenses (IOLs) that improve lens stability by, for example, increasing anterior-posterior stiffness of the IOL, increasing anterior-posterior dimensions of the IOL and/or increasing contact area with the equator of the bag to resist movement of the IOL as the bag collapses over time. These IOLs may be non-modular (single component) or modular (multiple component). In modular embodiments, the IOL system may include intraocular base and optic components, which, when combined, form a modular IOL.
Claims21
1-20. (canceled)
An intraocular lens, comprising:
- an optic portion defining an optical axis extending in an anterior-posterior direction;
- a support portion extending radially outward from a periphery of the optic portion;
- a haptic extending radially outward from the support portion;
- and
- a ridge extending in an anterior-posterior direction from a periphery of the support portion.
An intraocular lens, comprising:
- an optic portion;
- a support portion surrounding a periphery of the optic portion, the support portion including an anterior-facing surface and a posterior-facing surface;
- a haptic extending radially outward from the support portion;
- and
- a ridge extending in an anterior-posterior direction from a periphery of the support portion.
An intraocular lens, comprising:
- an optic portion having an anterior-facing surface and a posterior-facing surface;
- a support portion extending radially outward from the optic portion;
- a plurality of haptics extending radially outward from the support portion;
- and
- a plurality of discrete ridges extending in an anterior-posterior direction from peripheries of the haptics and a periphery of the support portion.
