Abstract: The present invention relates to a diffractive ocular implant with correct distance vision and enlarged near vision, which is charaterised, in particular, in that it has a phase-transfer curve as a function of thte viewing distance (abbreviated as PTFF-TF) with an absence of discontinuity over a depth of field of at least 1.3D in corneal plane, advantageously greater than 1.45D, said absence of discontinuity being located between intermediate vision and near vision, i.e. between 0.5D and 4D for spatial frequencies from 0 to 100 cycles/mm, for a pupil with a diameter of at least 3 mm.
