Abstract
A multi-component accommodating intraocular lens (A-IOL) for implantation in a capsular bag of an eye having an optical axis, includes an anterior optical element and a posterior component that are connected by at least one compressible haptic. The compressible haptic, by definition, has a deformation feature that is resiliently deformable. The deformation feature allows the nominal overall diameter of the A-IOL to dynamically vary over a selected range in response to a capsular bag dimension that is different than that of an average population value, or in response to a change in the size and/or shape of the capsular bag due to post-operative capsular bag shrinkage, without substantially changing the separation distance between the anterior and posterior components of the A-IOL absent an intended accommodating force. Methods are also disclosed.
