Over the last few years, several approaches have been proposed in order to improve the designs and the outcomes of accommodative intraocular lenses (AIOL). Most of the AIOLs described in the previous section based their mechanism of action in the axial movement of the optics. Even when accommodation may be achieved by these AIOLs, the main limitation of this design is that it is very dependent on the adequate function of the capsular bag. As we are all aware, fibrosis and contraction of the capsular bag will eventually develop after cataract removal, thus, AIOLs that are placed in this location progressively lose the capability of restoring the accommodation of the patient. This was the main reason to develop an AIOL that will be placed in other areas different to the capsular bag, such as the ciliary sulcus where it can also benefit from the forces of the ciliary muscle. Other designs that combine different mechani...
