[The multifocal intraocular lens].
The new multifocal intraocular lens gives 2 simultaneous foci by combination of conventional refraction and diffraction. The diffraction is induced by circular microsteps on the posterior face of the lens. The first clinical results are good: 3 patients out of 4 obtain a far-vision of 5/10 or better and a near-vision of P3 or better without spectacle correction.
