Abstract
Materials and methods of manufacturing intraocular lenses, including polymeric materials for the intraocular lenses, fluids for intraocular lenses, and adhesives for intraocular lenses. The intraocular lenses can include an optic portion and a peripheral region in fluid communication.
Claims11
A method of manufacturing at least one of a haptic and an optic portion of an intraocular lens, comprising:
- combining a plurality of monomers with an additional monomer comprising a hydroxyl moiety so as to create a pre-polymer, wherein the plurality of monomers comprise butyl acrylate, trifluoroethyl methacrylate, and phenylethyl acrylate;
- creating a cross-linkable polymer from the pre-polymer by converting the hydroxyl moiety into a cross-linkable methacrylate;
- and
- curing the cross-linkable polymer to form at least one of the haptic and the optic portion of the intraocular lens.
1 more element
A method of manufacturing an intraocular lens, comprising:
- forming a first body and a second body of the intraocular lens;
- applying an adhesive between the first body and the second body, wherein the adhesive comprises:
- a first primary component present in the adhesive in an amount between 55% to 75%, wherein the first primary component comprises:
- trifluoroethyl methacrylate;
- at least one of butyl acrylate and n-butyl methacrylate;
- and
- at least one of phenylethyl acrylate and phenylethyl methacrylate, and
- a second primary component present in the adhesive in an amount between 23% to 43%, wherein the second primary component is a reactive acrylic monomer diluent;
- and
- adhering the first body to the second body by curing the adhesive.
