1. An intraocular lens comprising: a refractive shape based on a refractive profile, wherein the refractive profile is based on a final wavefront power profile determined by adding to a first wavefront power profile a second wavefront power profile comprising a plurality of optical add powers at different radial positions, wherein the first wavefront power profile corresponds to a base power profile, wherein at least a first optical add power of the plurality of optical add powers follows the base power profile, and wherein the refractive profile has a maximum power peak at a radial position between approximately 0.5 mm and approximately 1.1 mm from an optical axis of the intraocular lens and wherein an entirety of the refractive profile is defined by a cosine function, wherein the final wavefront power profile has a starting sagittal power which extends from the center of the intraocular lens or its optical axis, which corresponds to the first wavefront power profile, and which decreases from an initial value in the range of 0 to −0.5 diopters.
