- A refractive multifocal intraocular lens, used to replace the lens of the eye, comprising a front optical surface and a back optical surface in its optic region, both surfaces being aspheric and cut from a predetermined transparent material, said front optical surface and back optical surface further being separated by a predetermined central thickness, characterized in that : a) an elevation map of each of said front optical surface and back optical surface has rotational symmetry with respect to the optical axis of said lens and a progressive and continuous evolution along the entire topography, b) an elevation along the radial coordinate on both said front optical surface and back optical surface, taking the tangential plane to the corneal apex as a reference, has a local minimum of zero, which corresponds to the centre of said lens, said elevation further presenting one or more turning points of curvature before reaching at least one peripheral local maximum, situated inside said optic region and at a predetermined distance from the edge of said optic region, giving rise to a topography that presents a local elevation minimum in the centre and at least one ring inside said optic region that presents a local elevation maximum, and c) a map of local optical strength inside said optic region, resulting from the combined optical refraction of said two aspheric optical surfaces and a model cornea, which is external and to the front of said lens, has rotational symmetry around the optical axis, and a central region of intermediate optical strength, surrounded by a ring of maximum optical strength with a progressive transition between them, after which rings of varying strength alternate progressively and in particular at least one ring, the optical strength of which represents a local minimum, with at least one ring, the optical strength of this represents a local maximum. a) an elevation map of each of said front optical surface and back optical surface has rotational symmetry with respect to the optical axis of said lens and a progressive and continuous evolution along the entire topography, b) an elevation along the radial coordinate on both said front optical surface and back optical surface, taking the tangential plane to the corneal apex as a reference, has a local minimum of zero, which corresponds to the centre of said lens, said elevation further presenting one or more turning points of curvature before reaching at least one peripheral local maximum, situated inside said optic region and at a predetermined distance from the edge of said optic region, giving rise to a topography that presents a local elevation minimum in the centre and at least one ring inside said optic region that presents a local elevation maximum, and c) a map of local optical strength inside said optic region, resulting from the combined optical refraction of said two aspheric optical surfaces and a model cornea, which is external and to the front of said lens, has rotational symmetry around the optical axis, and a central region of intermediate optical strength, surrounded by a ring of maximum optical strength with a progressive transition between them, after which rings of varying strength alternate progressively and in particular at least one ring, the optical strength of which represents a local minimum, with at least one ring, the optical strength of this represents a local maximum. <EOS>
