The present invention discloses methods of obtaining ophthalmic lens capable of reducing the aberrations of the eye comprising the steps of characterizing at least one corneal surface as a mathematical model, calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model, selecting the optical power of the intraocular lens. From this information, an ophthalmic lens is modeled so a wavefront arriving from an optical system comprising said lens and corneal model obtains reduced aberrations in the eye. Also disclosed are ophthalmic lenses as obtained by the methods which are capable reducing aberrations of the eye.
L'invention concerne des procédés de production de lentilles ophtalmiques capables de réduire des aberrations de l'oeil. Les procédés comprennent les étapes consistant à : caractériser au moins une surface cornéenne comme modèle mathématique, calculer les aberrations résultant de la ou des surfaces cornéennes au moyen du modèle mathématique, sélectionner la puissance optique du cristallin artificiel. A partir de ces informations, une lentille ophtalmique est modélisée de sorte qu'un front d'onde provenant d'un système optique comportant cette lentille et le modèle cornéen permet de réduire des aberrations de l'oeil. L'invention concerne aussi des lentilles ophtalmiques obtenues à l'aide des procédés, qui sont capables de réduire des aberrations de l'oeil.
