Patent ID: 8388681

Claim:
A method for making an intraocular lens (IOL) optic, the method comprising: a) forming a lens-grade polymer disc structure with a well centrally defined therein; b) filling said well with a visible light absorbing dye; c) covering said polymer structure and said well containing said visible light absorbing dye with a polymer to form a dye-containing polymer structure; and d) milling said dye-containing polymer structure to form said intraocular lens optic, wherein said visible light absorbing dye is entirely enclosed by the polymer disc structure as a discrete central region within the optic such that the visible light absorbing dye does not contact either the eye's anatomical structures or physiological fluids, wherein the visible light absorbing dve absorbs visible light between the wavelengths of 400λ and 550λ, wherein the visible light absorbing dye is a methine class dye having a concentration which is constant regardless of diopter strength, and wherein the discrete central region has a diameter less than about 4.5 mm.
