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.

Trifocal intraocular lens with extended range of vision and correction of longitudinal chromatic aberration

An intraocular lens () including an anterior surface () and a posterior surface () and having a substantially antero-posterior optical axis (). In this lens, one of these anterior and posterior surfaces includes a first diffractive profile () forming at least one first diffractive focal point () of order +1 on said optical axis, and a second diffractive profile () forming a second diffractive focal point () 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.

Providing multi-focal visual correction includes determining a plurality of visual conditions to which an eye is to be exposed, determining effects of the visual conditions on a pupil of the eye, and determining a target wavefront profile on the basis of the effects.

Ocular wavefront-correction profiling

Providing multi-focal visual correction includes determining a plurality of pupil conditions for an eye and determining a target wavefront profile on the basis of the plurality of pupil conditions.
