1. An intraocular lens comprising:

  • a central optic portion for focusing light, the optic portion defining a first chamber;

    a peripheral portion outward of the optic portion, the peripheral portion comprising a first polymer and defining a second chamber;

    a selected fluid media disposed within the first and second chambers; and

    a microporous body portion intermediate the first and second chambers, the microporous body portion selectively providing fluid communication of the selected fluid media between the first and second chambers,wherein the peripheral portion further comprises a second polymer that undergoes dimensional change in response to light energy application, the dimensional change causing transfer of the selected fluid between the first and second chambers.
