An intraocular lens 1 includes a lens 2 and a haptic 3 connected to the lens 2. The lens 2 is disposed behind an iris 7 in an eye of a patient. The haptic 3 has a main body 3a and first and second projections 3d and 3e. The main body 3a extends from the lens 2 outward in a radial direction about a visual axis C of the patient. The first and second projections 3d and 3e are located so as to project from the main body 3a toward spaces between a plurality of ciliary zonules 10 connecting a crystalline lens 11 and a ciliary body 8 in the eye. Accordingly, an intraocular lens and a haptic for an intraocular lens that are able to inhibit the position of a lens from being displaced are provided.
