Abstract
Provided is an intraocular lens capable of being reliably fixed into an eye from which an eye lens is extracted without suturing. The intraocular lens includes a pair of nipping portions which is formed at the right and left sides of a lens portion and a leg portion which extends from a limbus of the lens portion or each nipping portion. The nipping portion nips a part of the rear side of an iris inside the eye. A front end of the leg portion comes into contact with the deepest portion of a ciliary sulcus. The intraocular lens is reliably fixed to a rear section without suturing by the nipping of the nipping portion and the contacting of the leg portion.
