Abstract
The invention relates to a novel artificial intraocular lens (IOL) and a method for improving such a lens in the field of ophthalmology, with surface shape modifications that differ from perfect spherical geometries. The intraocular lens takes into account the natural optical configuration of the human vision apparatus, for example, visual axis tilt and pupil decentration. In addition, the method accounts for potential positioning errors caused by implantation and surgery effects.
