Abstract
An intraocular lens for providing accommodative vision to a subject includes a frame disposed about an optical axis, a first optical element, a second optical element, and a connecting element operably coupling the frame to the optical elements. The frame comprises an anterior frame element and a posterior frame element. The connecting element is configured to convert a first displacement between the frame elements in a direction that is substantially parallel to the optical axis into a second displacement between the optical elements that is substantially perpendicular to the optical axis. The second displacement may be translational and/or rotation. In some embodiments, the optical elements are two varifocal lenses.
