  • Publication number: 20230248509
    Abstract: Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.

  • Publication number: 20230191730
    Abstract: Disclosed are methods, systems, and apparatus for manufacturing an ophthalmic lens component. In one embodiment, a method includes placing at least part of a soluble core component on a first molding surface of a first mold component or a second molding surface of a second mold component, mating the second mold component to the first mold component to form an assembled mold comprising a mold cavity, introducing a lens component material into the mold cavity, curing the lens component material within the assembled mold to form a molded lens component, and immersing the molded lens component in a solvent to dissolve the soluble core component. At least one of the first mold component and the second mold component can also be made of a soluble material.
