1. 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. |
