Abstract
A method for testing multifocal intraocular lenses and intraocular lenses having designed-in optical aberrations. The method includes the providing of a nullifying lens having an optical zone configured such that light passing through the optical zone and through the intraocular lens is focused at a single plane if the intraocular lens does not contain any fabrication flaws. The invention further includes a nullifying lens constructed such that light passing through the nullifying lens and through an intraocular lens is focused at a single plane if the intraocular lens does not contain any fabrication flaws.
