1. An IOL, comprising:
- a first diffractive region; and
a second diffractive region having a power of a different magnitude than the first diffractive region, the first region adapted to diffract substantially all light at a first selected wavelength projected therethrough into a single non-zero order of diffraction, and the second region adapted to diffract substantially all light at a second selected wavelength projected therethrough into a single non-zero order of diffraction.

Abstract
An IOL, comprising a first diffractive region, and a second diffractive region having a power of a different magnitude than the first diffractive region, 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.

11. A method, comprising:
-
projecting light of a selected wavelength onto a first diffractive region and a second diffractive region of an IOL, the first region having a first diffractive optical power and the second region having a second diffractive optical power of a different magnitude than the first diffractive optical power; diffracting substantially all light of a first selected wavelength projected onto the first region into a single non-zero order of diffraction; and diffracting substantially all light of a second selected wavelength projected onto the second region into a single non-zero order of diffraction. - View Dependent Claims (12, 13, 14)
