Abstract:
1. 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 haptic 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.
