A foldable intraocular lens, made from a foldable soft material, for implantation in a ciliary sulcus of an eye having an iris, is provided with an optically active lens part having an optical axis and at least four haptics unitary with the optically active lens part and uniformly spaced about a periphery of the optically active lens part.The optically active lens part having a non-convex rim between any two neighboring haptics being free from surface irregularities that interfere with the iris.Each haptic comprising a closed loop, and a shoulder connecting the loop with the optically active lens part, the haptic loops being elastically deformable in a plane perpendicular to the optical axis of the optically active lens part in a direction toward the optically active lens part.
