Abstract
A color-apodized intraocular lens includes a lens center, with a center-transmittance to transmit an incident light; a lens annul us, surrounding the lens center, configured to selectively attenuate the incident light according to a radius- and wavelength-dependent annulus-transmittance, wherein the annulus-transmittance is less than the center-transmittance, in a short wavelength spectral range; and haptics, extending from the lens annulus. A method of making a color-apodized intraocular lens includes creating an intraocular lens mold using a base-polymer, the intraocular lens having a lens center, with a center-transmittance to transmit an incident light; a lens annulus, surrounding the lens center, configured to selectively attenuate the incident light according to a radius and wavelength-dependent annulus-transmittance, wherein the annulus-transmittance is less than the center-transmittance in a short wavelength spectral range; forming haptics, extending from the lens annulus; and applying a stimulus to the intraocular lens mold to form the color-apodized intraocular lens.
