Apparatus and Methods for 3D Printing Intraocular Lens Components
Summary
USPTO published patent application US20260096877A1 for Alcon Inc., covering apparatus and methods for 3D printing intraocular lens components, including formulations with monomers, crosslinkable polymers, crosslinkers, and photoinitiators. The patent also discloses a 3D printer system with reservoir, build platform, light source, and projection optics for curing lens layers. The application was filed September 11, 2025, with application number 19326387.
What changed
USPTO published Alcon's patent application covering 3D printing technology for intraocular lens components, including specific formulation compositions and printer apparatus. The patent describes methods using monomers, crosslinkable polymers, crosslinkers, and photoinitiators to produce lens materials, along with a complete 3D printing system featuring a reservoir, build platform, light source, and projection optics for layer-by-layer curing.
Manufacturers and medical device companies developing ophthalmic or lens-related products should monitor this patent for potential licensing implications or freedom-to-operate considerations. R&D teams working on 3D-printed ocular devices may need to evaluate whether their technology overlaps with Alcon's protected claims.

Abstract
Disclosed are apparatus and methods for 3D printing intraocular lens components, intraocular lens formulations suitable for 3D printing, and 3D-printed intraocular lens components. In one aspect, the intraocular lens formulation can comprise a plurality of monomers, a crosslinkable polymer comprising the plurality of monomers, a crosslinker, and a photoinitiator. Also disclosed is a 3D printer for printing an intraocular lens component. The 3D printer can comprise a reservoir configured to contain an intraocular lens formulation, a build platform comprising a build surface configured to be initially in fluid contact with the intraocular lens formulation within the reservoir, a light source configured to generate a light, and at least one of a mirror and a projection optic configured to direct the light generated by the light source at the intraocular lens formulation within the reservoir to cure and form one layer of the intraocular lens component on the build surface.
