An intraocular lens (IOL) includes a first optic, a first set of haptics extending from the first optic, a second optic, a second set of haptics extending from the second optic, and a hinge joining the first and second sets of haptics. The IOL is subject to a pre-bias that biases the first and second optics away from one another along an anterior-posterior (A-P) axis. The IOL is also provided with a restraining element that restrains the optics relative to each other in a stressed, planar, non-accommodating configuration during implantation and a post-operative period. The restraining element extends across a portion of at least one of the first and second optics, but is not reliant on use of the haptics for support thereof. Upon release of the restraining element, the optics can move relative to each other along the A-P axis in accommodation.
