<P>PROBLEM TO BE SOLVED: To provide a method of designing a multifocal ophthalmic lens with one base focus and at least one additional focus, capable of reducing aberrations of the eye for at least one of the foci after its implantation. <P>SOLUTION: The method includes the steps of: (i) characterizing at least one corneal surface as a mathematical model; (ii) calculating the resulting aberrations of the corneal surfaces by employing the mathematical model; (iii) modelling the multifocal ophthalmic lens such that a wavefront arriving from an optical system comprising the lens and the at least one corneal surface obtains reduced aberrations for at least one of the foci. There is also disclosed a method of selecting a multifocal intraocular lens, a method of designing a multifocal ophthalmic lens based on corneal data from a group of patients, and a multifocal ophthalmic lens. <P>COPYRIGHT: (C)2010,JPO&INPIT |
