摘要:
Disclosed is an intraocular lens (IOL) including an anterior surface, a posterior surface and an optical axis. At least one of the anterior or posterior surfaces has a diffractive profile formed thereon. The diffractive profile has diffractive focal points for far vision, intermediate vision, and near vision. The diffractive profile corresponds to a superposition of a first partial diffractive profile and a second partial diffractive profile, the first partial diffractive profile has a focal point of order +n that coincides with the diffractive focal point for intermediate vision or with the diffractive focal point for near vision, the second partial diffractive profile has a focal point of order +n that coincides with the diffractive focal point for far vision and a focal point of higher order than +n that coincides with the diffractive focal point for near vision.
