  • a longitudinally extending hollow shank having a body and a tip portion;

    flexible band means forming a loop extending forwardly of said tip portion for embracing the intraocular lens,said shank tip portion having a generally S-shape to allow said tip portion to curl around the iris of the eye to position said loop with the intraocular lens held therein inside the posterior capsule in a plane generally parallel to the posterior wall of the capsule; and

    support means displaceable within said hollow shank and connected to said band means;

    said displaceable support means having in said hollow shank a forward position in which said loop is larger than the lens to be held therein, an intermediate position in which said loop snugly retains the lens, and a rearward position in which said band means releases the lens to enable withdrawal of said band means from the eye without disturbing the seating of the lens in the posterior capsule of the eye.
