INTRAOCULAR LENS FOR ACHROMATISING THE EYE AND REDUCING THE ABERRATIONS THEREOF

摘要

The invention relates to the use of an intraocular lens (IOL) which is designed to be implanted in a human eye. The inventive lens comprises a first surface (1) and a second surface (2) having different optical properties, one of said surfaces being diffractive and the other refractive. The first (1) and second (2) surfaces define a structure comprising a plurality of optical properties in order to reduce monochromatic spherical aberrations, chromatic aberrations and spherical/chromatic aberrations. According to the invention, the following surfaces can be combined: aspherical diffractive, spherical diffractive, spherical refractive, aspherical refractive. The spherical surfaces can be replaced by flat surfaces.
