Abstract
Optical characteristics and properties of AcrySof ReSTOR® bifocal intraocular lenses (Alcon, USA) and elastic polymer MIOL-Akkord lenses (Russia) are compared. The lenses differ by the form of refractive component, the type of diffractive microstructure, and their fabrication technology. Investigations showed that the lenses have similar optical characteristics in resolution, but the bifocal properties of the MIOL-Akkord are much less dependent on the pupil diameter.
