Abstract
An implantable intraocular lens and methods of manufacturing them provide a target degree of optical accommodation. In various embodiments, the lens includes at least one internal optic, an outer shell for enclosing at least a portion of the internal optic, and a fluid at least partially filling the outer shell.
Claims18
An implantable intraocular lens comprising:
- an outer shell comprising at least a first external-access refill valve;
- at least one internal fluid-filled lens including a portion integrated with at least a portion of the outer shell and comprising at least a second external-access refill valve distinct from the first external-access refill valve, the integrated portion of the intraocular lens being thicker and less flexible than, and accommodating differently from, unintegrated portions of the intraocular lens;
- and
- a first fluid at least partially filling the outer shell,
- wherein a refractive index of the first fluid, a degree of filling of the outer shell with the first fluid, a curvature of the outer shell, an axial position of the at least one internal fluid-filled lens, and a curvature of the at least one internal fluid-filled lens cooperate to define an accommodation and a refractive power of the intraocular lens.
