  • Publication number: 20260096877
    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.

  • Patent number: 12521948
    Abstract: The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; bring a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.

  • Publication number: 20230301778
    Abstract: Certain embodiments provide an intraocular lens (IOL) including a lens body having an anterior lens element and a posterior lens element, and an optical fluid in a cavity formed between the anterior lens element and the posterior lens element. The anterior lens element and the posterior lens element each comprise a lens material having a first Abbe number, and the optical fluid has a second Abbe number that is less than the first Abbe number.
