figures rectangular triangular or the like the straps 16 and hinges 17 function by allowing the optic to move anteriorly and posteriorly the approximately 1 0 2 0 mm wide straps are a point of relative weakness in the plane of the lens body 12 encircling the optic 14 thereby allowing the entire optic 14 to herniate forward anteriorly from its far posterior position in a translational forward movement this feature is enhanced by keeping the mass of the optic 14 to a minimum as described below this new mechanism may boost the effect of the other features of the lens rather than a fluid filled sac pushing through an aperture as in some prior lenses the present lens involves a deformable solid optic moving anteriorly and posteriorly through a hinged area 16 in the plate or body 12 central hinges 18 on the anterior side of the body 12 hinging the haptics 15 further facilitate movement of the optic with ciliary muscle contraction fig1 b shows an alternative embodiment with a pair of hinges 51 as shown in alignment with the edges of the optic rather than the hinges 18 of significance is the manner in which the optic 14 and haptic plates 15 move in accommodating from distance to near vision and this is particularly illustrated in fig8.
