摘要： Intraocular lenses (IOLs) and related methods. One embodiment provides an IOL which includes a lens optic and a pair of haptics. The haptics can be coupled to the lens optic and can cause compression of the lens optic when the IOL is fixated in an eye. The lens optic can have a compressed geometry, an uncompressed geometry including an aberration, and a desired geometry. The compressed geometry can be the desired geometry. The aberration can be astigmatism, coma, or spherical aberration. For instance, the aberration can be astigmatism of about 0.17 D at the spectacle plane and of about 0.25 D at the intraocular lens plane. Moreover, the haptics can define a first axis between the haptics; the lens optic can define a second axis perpendicular to the first axis; and the uncompressed geometry can differ from the compressed geometry in the vicinity of the second axis.

摘要： An intraocular lens providing pseudo-accommodation includes a haptic assembly configured to position the accommodating intraocular lens; and a meniscus-shaped optic having a convex face and a concave face. The meniscus-shaped optic has an uncompressed state within an eye when the ciliary muscles are relaxed and a compressed state within the eye when the ciliary muscles are contracted. A principal plane of the meniscus-shaped optic in the uncompressed state is anterior to the principal plane of the meniscus-shaped optic in the compressed state. A spherical aberration of the meniscus-shaped optic is substantially different in the compressed state than in the uncompressed state.
