Abstract

A prosthetic eye or aesthetic contact lens and methods of manufacture of the same using additive manufacturing. Methods may include scanning a functional eye of a user to generate a prosthetic eye model matching the coloring and sizing features of the scanned eye. A substrate is positioned relative to one or more print heads, which deposit polymerizable mixtures as deposited droplets to form the sclera portion, vein pattern, and iris structure. A first polymerizable mixture may replicate a natural sclera, a second polymerizable mixture may form natural features, such as vein patterns, and a third polymerizable mixture may create an iris with a pupil region. The prosthetic eye may include an internal cavity filled with a liquid solution to allow iris movement, liquid pouches for hydration or medication, and integrated electronic components such as cameras, sensors, and wireless communication modules.

Dependent claims

A method of forming a prosthetic lens, comprising the steps of:

a.) generating a digital model of a desired configuration of at least an iris and/or pupil for a patient, wherein said digital model substantially replicates coloring of the desired at least iris and/or pupil;
b.) using the digital model to program one or more additive manufacturing printheads to:
deposit a first volume of polymerizable mixture in a predetermined pattern onto a receiving surface of a substrate as a first volume of deposited droplets, and
deposit at least a second volume of polymerizable mixture in a predetermined pattern onto said substrate and/or said first volume of deposited droplets;
c.) integrating a portion of the first volume and at least second volume to form a combined volume of polymerizable mixture;
d.) pinning the combined volume of polymerizable mixture to cause partial polymerization of the combined volume of polymerizable mixture;
e.) repeating steps b.) through d.) until the successive deposited volumes of polymerizable mixture substantially replicates the digital model;
and
f.) fully curing all polymerizable mixture,
wherein one or more volumes of polymerizable mixture deposited include one or more embedded pigments that collectively substantially replicate the coloring of the desired iris and/or pupil, and
wherein at least the last successive deposited volume of polymerizable mixture is transparent.
