Zusammenfassung:	Intraocular lens and methods for optimization of depth of focus and the image quality in the periphery of the visual field. The intraocular lens (600) comprises a central part and a peripheral part, the central part being the optical part (600) and the peripheral part comprising mechanical fasteners (603), and the central part comprises:- an aspherical concave anterior surface (601), which is the surface closest to the iris of the eye once the lens (600) has been implanted in the eye, and- an aspherical convex posterior surface (602), which is the surface closest to the retina of the eye once the lens (600) has been implanted in the eye,such that:- the radius of curvature of the posterior surface (602) of the central part is smaller than the radius of curvature of the anterior surface (601) of the central part, with a ratio between radii of between 2 and 6, and- the mechanical fasteners (603) are arranged at an angle (605) of between 0° and 10° with respect to a plane passing through the joints between the central part and the peripheral part and which is perpendicular to the optical axis of the eye in which the lens (600) is intended to be implanted.
