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 hinges 18 on the anterior side of the body 12 hinging the haptics 15 further facilitate movement of the optic with ciliary muscle contraction 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 and 9 with respect to anterior a and posterior b reference lines in these figs as is usual the ends of the haptics 15 or the loops 24 as the case may be are implanted in the capsular bag such that the optic 14 is vaulted posteriorly for distance vision as seen in fig8 the optic 14 moves anteriorly for near vision as shown in fig9 upon ciliar muscle contraction in particular the whole lens moves forward a little as seen in fig9 and the haptic plates 15 move centrally and backward slightly in the direction of arrows 44 which results in a pressure caused by ciliary muscle contraction in further increase in pressure on the optic 14 that pushes the optic further forward because the hinge or hinges 17 are thin and stretch a little and the optic deforms somewhat this provides an increase in anterior optic movement with optic deformation also the ends.
