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 1, one of these anterior and posterior surfaces 4, 5 includes a first diffractive profile 9 forming at least one first diffractive focal point 11 of order +1 on said optical axis 6, and a second diffractive profile 10 forming a second diffractive focal point 12 of order +1 on said optical axis 6 which is distinct from the first diffractive focal point 11 of order +1. At least one portion of said second diffractive profile 10 is superposed to at least one portion of the first diffractive profile 9. Fig. 3.
