Abstract: This ocular implant permits correction of various forms of ametropia. It comprises, on or within one and the same support (6) implantable in the eye (4), a first lens (9) which is fixed and defines an optic axis (A), and a second lens (11) which is movable between a position in which it is laterally offset from the first lens (9) and a position in which it is superposed on the first lens (9), along the same optic axis (A). One position is provided in particular for far vision, and the other position for near vision. The displacement of the second lens (11), between its two positions, can be controlled from the outside by magnetic means.
