1. A method of adjusting an accommodating intraocular lens, comprising:
adjusting a base power of the accommodating intraocular lens by directing an external energy at a composite material within at least one of an optic portion and a peripheral portion of the accommodating intraocular lens,
wherein the composite material comprises an energy absorbing constituent and a plurality of expandable components,
wherein the optic portion comprises a fluid-filled optic fluid chamber and the peripheral portion comprises at least one haptic comprising a fluid-filled haptic fluid chamber in fluid communication with the optic fluid chamber, wherein the method further comprises directing the external energy at the composite material to displace fluid between the optic fluid chamber and the haptic fluid chamber,
wherein the optic portion is configured to deform, flex, or change shape in response to fluid entering or exiting the optic fluid chamber, and
wherein the plurality of expandable components are expandable microspheres, wherein each of the expandable microspheres comprises a blowing agent contained within a thermoplastic shell.
