The accommodating lens was designed to improve distance, intermediate, and near acuity via the movement of its hinged haptics during the accommodative process. Currently, 1 accommodating IOL design (and a similar toric accommodating IOL) has been approved for use by the US Food and Drug Administration (FDA). The accommodating IOL provides some degree of improved intermediate vision (Fig 9-3). A possible mechanism of action that would explain this improvement is that this IOL provides some pseudoaccommodative depth of focus, because there is no clear clinical evidence that these “accommodating” IOLs change axial position in the eye during near-vision tasks.
