Abstract
Disclosed are adjustable intraocular lenses and methods of adjusting intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and at least one haptic. At least part of the haptic can be made in part of a composite material comprising an energy absorbing constituent and a plurality of shrinkable and/or burstable microspheres. At least one of a base power of the optic portion can be configured to change in response to an external energy directed at the composite material.
Claims20
An intraocular lens, comprising:
- an optic portion;
- one or more haptics coupled to the optic portion;
- wherein at least one of the haptics comprises a composite material, wherein the composite material comprises an energy absorbing constituent and a plurality of at least one of shrinkable microspheres and burstable microspheres, and
- wherein a base power of the optic portion is configured to change in response to an external energy directed at the composite material.
A method of adjusting an intraocular lens, comprising:
- adjusting a base power of the intraocular lens by directing an external energy at a composite material within at least one haptic of the intraocular lens,
- wherein the composite material comprises an energy absorbing constituent and a plurality of at least one of shrinkable microspheres and burstable microspheres.
An intraocular lens, comprising:
- an optic portion;
- and
- at least one haptic coupled to the optic portion,
- wherein the at least one haptic comprises a first composite material, wherein the first composite material comprises an energy absorbing constituent and a plurality of at least one of shrinkable microspheres and burstable microspheres,
- wherein a portion of the at least one haptic is made in part of a second composite material comprising the energy absorbing constituent and a plurality of expandable microspheres,
- wherein a base power of the optic portion is configured to decrease in response to an external energy directed at the first composite material, and
- wherein the base power of the optic portion is configured to increase in response to the external energy directed at the second composite material.
A size-adjustable ophthalmic material, comprising:
- an energy absorbing constituent;
- and
- a plurality of at least one of shrinkable microspheres and burstable microspheres, and
- wherein a size of the ophthalmic material is configured to change in response to an external energy directed at the ophthalmic material.
