摘要：
Disclosed is an intraocular lens (10) (IOL) including an anterior surface (16), a posterior surface (18) and an optical axis (20), wherein on at least one of the anterior or posterior surfaces (16, 18) a diffractive profile (24) is formed, said diffractive profile (24) providing for a diffractive focal point (30) for far vision, a diffractive focal point (32) for intermediate vision, and a diffractive focal point (34) for near vision. The said diffractive profile (24) corresponds to a superposition of a first partial diffractive profile (26) and a second partial diffractive profile (28), wherein the first partial diffractive profile (26) has a focal point of order +n that coincides with the diffractive focal point for intermediate vision (32) or with the diffractive focal point for near vision (30), the second partial diffractive profile (28) has a focal point of order +n that coincides with the diffractive focal point (30) for far vision, and a focal point of higher order than +n of the second partial diffractive profile (28) coincides with the diffractive focal point (34) for near vision.
