    摘要: The invention relates to an intraocular lens (1) including an anterior surface (4) and a posterior surface (5) and having a substantially antero-posterior optical axis (6). In this lens, one of these anterior and posterior surfaces includes a first diffractive profile (9) forming at least one first diffractive focal point (11) of order +1 on said optical axis, and a second diffractive profile (10) forming a second diffractive focal point (12) of order +1 on said optical axis which is distinct from the first diffractive focal point of order +1. At least one portion of said second diffractive profile is superposed to at least one portion of the first diffractive profile.
