Abstract
Disclosed are adjustable intraocular lenses and methods of adjusting intraocular lenses post-operatively. In one embodiment, an adjustable intraocular lens can comprise an optic portion and a peripheral portion. The peripheral portion can comprise a composite material comprising an energy absorbing constituent and a plurality of expandable components. A base power of the optic portion can be configured to change in response to an external energy directed at the composite material.
Claims19
An adjustable static-focus intraocular lens, comprising:
- an optic portion;
- and
- a peripheral portion coupled to the optic portion,
- wherein the peripheral portion comprises a composite material comprising an energy absorbing constituent and a plurality of expandable components, wherein the expandable components are expandable microspheres, and wherein each of the expandable microspheres comprises a blowing agent contained within a thermoplastic shell, and
- wherein a base power of the optic portion is configured to change in response to an external energy directed at the composite material.
An adjustable static-focus intraocular lens, comprising:
- an optic portion;
- and
- a peripheral portion coupled to the optic portion,
- wherein the peripheral portion comprises a composite material comprising an energy absorbing constituent and a plurality of expandable components, wherein each of the expandable components comprises a blowing agent contained within a thermoplastic shell, and wherein the blowing agent is expandable, wherein a base power of the optic portion is configured to change in response to an external energy directed at the composite material.
An adjustable static-focus intraocular lens, comprising:
- an optic portion;
- and
- a peripheral portion coupled to the optic portion,
- wherein the peripheral portion comprises a composite material comprising an energy absorbing constituent and a plurality of expandable components, wherein each of the expandable components comprises a blowing agent contained within a thermoplastic shell, and wherein the thermoplastic shell is made in part of nitriles or acrylonitrile copolymers, wherein a base power of the optic portion is configured to change in response to an external energy directed at the composite material.
