Intraocular meniscus lens providing pseudo-accommodation

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...

Beschreibung
Zusammenfassung:	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.
