Accommodating intraocular lens assemblies and accommodation measurement implant

A haptics system for retaining an accommodating intraocular lens (AIOL) in a human eye having a visual axis and including a sclera of tough connective tissue, an annular ciliary sulcus, and a sphincter-like ciliary body having a relaxed state for tensioning a capsular diaphragm in an anterior direction along the visual axis,

• the AIOL having an anterior surface and a posterior surface, and at least one shape memory optical element resiliently elastically deformable between a natural shape with a first Diopter strength and a deformed shape with a second Diopter strength different than the first Diopter strength whereby the AIOL has a continuously variable Diopter strength between a minimum Diopter strength for distance vision purposes and a maximum Diopter strength for near vision purposes,
• the haptics system comprising a main body with a longitudinal axis intended to be co-directional with the human eye's visual axis and at least two haptics tangentially extending from said main body in opposite directions in a plane perpendicular to said haptics system's longitudinal axis, and each with at least one pointed puncturing member for penetrating the tough connective tissue of the human eye's sclera for self-anchoring implantation in the human eye's annular ciliary sulcus at at least two spaced apart stationary anchor points for retaining the AIOL along the human eye's visual axis,
• wherein each haptics of said at least two haptics has a thin profile in said plane perpendicular to said haptics system's longitudinal axis such that said at least two haptics are sufficiently flexible for encircling around said main body and a wide profile along said haptics system's longitudinal axis for holding the AIOL rigid against a compressive force therealong such that relaxation of the human eye's ciliary body urges the human eye's capsular diaphragm against the AIOL's posterior surface from a posterior direction for affecting the AIOL's Diopter strength.

A discrete accommodating intraocular lens (AIOL) for implantation in a human eye having a visual axis and including a sclera of tough connective tissue, an annular ciliary sulcus, and a sphincter-like ciliary body having a relaxed state for tensioning a capsular diaphragm in an anterior direction along the visual axis,

• a discrete haptics system having a tubular main body with a longitudinal axis and at least two haptics each with at least one pointed puncturing member for penetrating the tough connective tissue of the human eye's sclera for self-anchoring implantation in the human eye's annular ciliary sulcus at at least two spaced apart stationary anchor points for retaining the AIOL along the human eye's visual axis at an in situ selectively displaceable desired position therealong relative to the at least two spaced apart stationary anchor points,
• the AIOL comprising a discrete tubular casing having a longitudinal axis, an anterior surface and a posterior surface, and at least one shape memory optical element resiliently elastically deformable between a natural shape with a first Diopter strength and a deformed shape with a second Diopter strength different than said first Diopter strength whereby the AIOL has a continuously variable Diopter strength between a minimum Diopter strength for distance vision purposes and a maximum Diopter strength for near vision purposes;
• said posterior surface being urged against the human eye's capsular diaphragm from an anterior direction for determining the AIOL's Diopter strength at the desired position such that relaxation of the human eye's ciliary body urges the human eye's capsular diaphragm against said posterior surface from a posterior direction for affecting said AIOL's Diopter strength.
