Accommodating intraocular lens assemblies and accommodation measurement implant
The present invention pertains to accommodating intraocular lens (AIOL) assemblies including a haptics system for self-anchoring implantation in a human eye's annular ciliary sulcus for retaining an AIOL at a desired position along the human eye's visual axis, and an accommodation measurement implant (AMI) for determining accommodation and accommodation forces in an experimental set-up including an animal's eye.
1. An accommodating intraocular lens (AIOL) comprising:
an optical element containing a liquid, the optical element comprising an anterior-facing surface configured to be resiliently deformed to increase diopter strength of the optical element upon application of a compressive force against the optical element, wherein upon implantation of the AIOL in an eye, a visual axis of the eye extends through a central region of the anterior-facing surface and the anterior-facing surface forms an external surface of the accommodating intraocular lens;
a reciprocating member operatively coupled to the optical element, the reciprocating member comprising a trailing end and an opposite leading end, wherein upon implantation of the AIOL in the eye, the reciprocating member is reversibly movable in response to accommodative eye movements such that the trailing end of the reciprocating member is configured to contact eye tissue driving shape change of the AIOL so that the leading end of the reciprocating member is urged against the optical element to resiliently deform the anterior-facing surface outward due to application of the compressive force against the optical element by the leading end of the reciprocating member, thereby causing the increase in diopter strength; and
a haptics system coupled to and extending outward from the optical element.
2. The accommodating intraocular lens of claim 1 , wherein the haptics system comprises at least two haptics, each of the at least two haptics comprising a penetrating member.
3. The accommodating intraocular lens of claim 1 , whereby the reciprocating member is movable from a posterior direction to an anterior direction along the visual axis of the eye.
4. The accommodating intraocular lens of claim 1 , wherein the AIOL has a first Diopter strength for distance vision purposes at rest and upon deformation of the anterior-facing surface outward to a shape with a second Diopter strength higher than the first Diopter strength.
5. The accommodating intraocular lens of claim 1 , wherein the optical element further comprises an outer main body that is a ring having an axial length along a longitudinal axis, the ring surrounding an axial length of the optical element such that at least a portion of the optical element is contained by the main body.
6. The accommodating intraocular lens of claim 1 , wherein the liquid of the optical element comprises a silicone-based or water-based liquid.
7. The accommodating intraocular lens of claim 6 , further comprising a second optical element supported by an outer main body and optically aligned with the optical element.
8. The accommodating intraocular lens of claim 1 , wherein the haptics system forms at least two spaced apart, stationary anchor points upon implantation of the AIOL in the eye adapted to retain the AIOL in the eye.
