An adjustable intraocular lens is disclosed comprising at least one optical element (1,2) and at least one haptic. Rotation of the lens in a plane perpendicular to the optical axis (7,8) and bounded by an oval boundary adjusts the lens diameter which provides a corresponding adjustment of optical power. Preferably the lens according to the invention is adapted to be manipulated by manipulation means outside the eye, for example, surgical means. Adjustment of the angular position of the intraocular lens results in a corresponding adjustment of the lens diameter which, in turn, leads to a corresponding adjustment of the optical power of the lens.
