Abstract:
1. A method of changing an optical parameter of an accommodating intraocular lens; comprising: implanting an intraocular lens comprising an optic portion and a peripheral portion extending peripherally from the optic portion, wherein the optic portion comprises an optical axis extending in an anterior to posterior direction and passing through the center of the optic portion, an anterior element, a posterior element, and a flexible intermediate layer disposed between the anterior element and the posterior element, the optical axis passing through the flexible intermediate layer, wherein the flexible intermediate layer partially defines a channel in the optic portion that is in communication with the peripheral portion, wherein a flowable media is disposed in the channel in the optic portion and is capable of moving between the channel in the optic portion and the peripheral portion; and moving the flowable media between the channel in the optic portion and the peripheral portion in response to ciliary muscle movement to change an optical parameter of the intraocular lens, wherein moving the flowable media between the optic portion and the peripheral portion comprises moving the intermediate layer and at least one of the anterior element and the posterior element from a first configuration to a second configuration.
