摘要：

An IOL (100), comprising a first diffractive region (110), and a second diffractive region (120) having a power of a different magnitude than the first diffractive region (110), the first region adapted to diffract substantially all light at a first selected wavelength projected therethrough into a single order of diffraction, and the second region adapted to diffract substantially all light at a second selected wavelength projected therethrough into a single order of diffraction.
