  • Patent number: 12167959
    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.
    Type: Grant

  • Publication number: 20240325139
    Abstract: Disclosed herein are intraocular lenses comprising an optic portion and at least one haptic having a proximal end coupled to the optic portion and a distal end. The haptic comprising a haptic lumen extending through at least part of the haptic. The haptic can comprise one or more haptic isolators disposed within the haptic lumen. The one or more haptic isolators can be configured to counteract or reduce unintended shape changes caused by an external energy directed at the haptic.

  • Publication number: 20240325140
    Abstract: Disclosed herein are intraocular lenses with features that counteract the effects of anterior capsular contraction and methods for implanting such intraocular lenses. In some embodiments, the intraocular lenses can comprise an optic fluid chamber and a haptic having a haptic fluid lumen in fluid communication with the optic fluid chamber. The haptic fluid lumen can comprise a thickened anterior portion such that a thickness of the anterior haptic wall of the haptic is greater than the thickness of the posterior haptic wall. Moreover, the intraocular lenses can comprise one or more support columns disposed within the haptic fluid lumen. The support columns and/or the thickened anterior portion of the haptic can maintain a shape of the haptic fluid lumen in response to forces applied to the haptic as a result of anterior capsular contraction.

  • Publication number: 20230346541
    Abstract: Disclosed are toric accommodating intraocular lenses. In one embodiment, a toric accommodating intraocular lens comprises an anterior element and a posterior element. The anterior element can comprise an anterior optical surface. The posterior element can comprise a posterior optical surface. A fluid-filled optic fluid chamber can be defined in between the anterior element and the posterior element. The toric accommodating intraocular lens can be configured to correct for corneal astigmatism, spherical aberration, or a combination thereof.

  • 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.
