description | A composite light adjustable intraocular lens comprises an acrylic diffractive intraocular lens, having a diffractive structure and haptics; and a silicone light adjustable lens, attached to the acrylic diffractive intraocular lens. The diffractive structure produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision, wherein the constructive interference produces a near focal point, a distance focal point corresponding to the base power of the ophthalmic lens, and an intermediate focal point between the near focal point and the distance focal point and wherein a diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent. |
