<p>An intraocular lens includes an optical portion (7; 607; 907; 1107) of a transparent, deformable material, at least one haptic (5, 6; 205, 206; 405, 406, 706; 806; 905; 1005; 1105; 1205) radially projecting from the optical portio n for supporting the optical portion in a position parallel to and against an anterior iris surface plane (986; 1186), and at least one aperture (13; 213; 713; 913 ; 1013; 1113) bounded by the haptic. At least a stiff portion of the haptic ha s a higher stiffness against bending about an axis in the radial direction than the optical portion. furthermore, the stiff portion has a width (a) measured parallel to the plane and perpendicular to the radial direction, which is smaller tha n the size (b) of the optical portion in the direction of the width. An instrument and methods for preparing and carrying out insertion of such a lens are also described.</p> |
