The MIOL-Akkord bifocal intraocular lens (an artificial crystalline lens of the eye), in which a diffraction zone plate is used to provide near vision, has been created in order to reduce the dependence on eyeglass correction and to increase the range of sharp vision. The optical characteristics are investigated, and the developed lens is compared with an apodized diffraction-refraction lens made by the Alcon Corp. (USA).
