Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration.

Abstract: A multifocal ophthalmic lens includes an ophthalmic lens and a diffractive element. The ophthalmic lens has a base curvature corresponding to a base power. The diffractive element produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision. The constructive interference produces a near focus, a distance focus corresponding to the base power of the ophthalmic lens, and an intermediate focus between the near focus and the distance focus. A diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent.

Abstract: A diffractive quint focal intraocular lens includes a base optic and a diffractive element. The base optic has a base curvature that corresponds to a base power. The diffractive element provides constructive interference in at least five consecutive diffractive orders to create a set of five focal points for vision from near to distance. The constructive interference provides for a near focal point at the highest diffractive order of the five consecutive diffractive orders, a distance focal point at the lowest diffractive order, and three intermediate diffractive orders between the highest and lowest diffractive orders to provide continuity of vision from near to distance with an extended intermediate, an intermediate, and an extended near focal points. The multifocal intraocular lens (i) provides a diffraction efficiency of ?100%, (ii) creates almost no positive optical disturbance, (iii) may also reduce longitudinal chromatic aberration.
