Abstract: Provided is an intraocular lens including a lens and a pair of right and left loop-shaped support portions, and a folding-back portion is provided in the front end of each support portion. A sclera tunnel is formed in the circumferential direction at a position of a depth corresponding to the half of the thickness of the sclera in two symmetrical positions with respect to the visual axis in a portion adjacent to a limbus of the sclera. The front end of the support portion is extracted from the ciliary sulcus and is inserted into the sclera tunnel, so that the intraocular lens is fixed into the eye. Furthermore, at that time, the folding-back portion is hooked to a certain portion inside the sclera tunnel, so that the support portion is strongly restrained inside the sclera tunnel. As a result, the intraocular lens is more reliably fixed.
