Abstract:
1. An intraocular lens comprising: an optical portion of a transparent, deformable material; at least one haptic radially projecting from the optical portion for supporting the optical portion in a position parallel to and against an anterior iris surface plane, said at least one haptic comprising a proximal portion and a pair of flexible, pincer like arms projecting from said proximal portion and defining a nip between said arms for pinching and fixating an anterior surface portion of iris tissue; at least one aperture in the at least one haptic being bounded by and located between said pincer-like arms of the at least one haptic, wherein said at least one haptic is of a material having a higher specific stiffness against bending than material of the optical portion, such that flexing of the optical portion in a central zone in-line with said at least one haptic is counteracted, and wherein said at least one haptic has a width measured parallel to said plane and perpendicular to said radial direction, which is smaller than the size of the optical portion in the direction of said width, leaving flexibly deformable zones of said optical portion laterally of said central zone.
