For attaching an intraocular implant having pincher like clamping arms forming a pinching area between end portions of the clamping arms to an iris of an eye, the implant is positioned against a surface of the iris in the anterior chamber of the eye, a passage in a distal end portion of an ophthalmologic surgical instrument in the anterior chamber of the eye is positioned against a surface portion of the iris closely adjacent the pinching area, and suction is applied to the passage and at least one of the end portions of the clamping arms is urged towards the iris, causing a tuck of iris material adhered to the passage to be inserted into the pinching area. Thus, a tuck adhering to the passage can easily be introduced into the pinching area between the clamping arms. An instrument and an implant specifically adapted for this method are described as well.

Fixation of an intraocular implant to the iris

An intraocular lens includes 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 (), and at least one aperture () bounded by the haptic. At least a stiff portion of the haptic has 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 than 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.
