Abstract:
1. An intraocular lens for insertion into a lens capsule, comprising: a lens front film having a diameter and formed of a transparent elastic film; a transparent optical lens having a larger diameter than the diameter of the lens front film, positioned spaced apart from and in opposition to the lens front film in a direction of an optical axis; a flexible annular rear film extending to an outer peripheral side of the optical lens; an outer peripheral coupling portion positioned to an outer peripheral side of the lens front film and the annular rear film, and supporting an outside peripheral edge of the lens front film and an outside peripheral edge of the annular rear film respectively thereby secluding a space between opposed faces of the lens front film and the optical lens to produce a capsule structure; a transparent liquid or gel internal filler which fills an interior of the capsule structure between the opposed faces of the lens front film and the optical lens; and a positioning portion extending to an outer peripheral side from the outer peripheral coupling portion and contacting an inside wall of an equatorial portion of the lens capsule thereby positioning the outer peripheral coupling portion with respect to the lens capsule.
