Abstract: There is disclosed an intraocular lens which can easily obtain fine images of all objects in a range from a least distance of distinct vision to an infinity distance. The intraocular lens has: a lens unit including a convex lens, a hard magnetic material provided at the periphery portion of the convex lens, and a guidance member provided at the periphery portion of the lens unit; a cylinder-shaped flame unit for storing the lens unit therein, including a helical guidance groove formed on the inner surface thereof for meshing with a top of the guidance member of the lens unit and for carrying the lens unit along with the optical axis of the lens unit while rotating; and a pair of loop units for fixing the a cylinder-shaped flame unit storing the intraocular lens. The lens unit rotates by an application of magnetic force from outside thereby to move to a portion where the fine image formation of the desired object can be obtained.

Abstract: A device for adjusting a position of a focal point of an intraocular implant provided partially with a magnetic material and substituted for the crystalline lens and a magnetic flux generating spectacles for applying variable magnetism to the intraocular implant to attract the same so that the intraocular implant can be moved forward and backward with respect to the retina.
