1. A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens, the device comprising:

  • a posterior end comprising a refractive optic; and

    a plurality of petals extending radially outwardly from the posterior end,each petal of the plurality of petals comprising;

    a first curved lateral side,a second curved lateral side opposite the first lateral side, andan end,the device having a planar state, wherein, in the planar state;

    the ends of the plurality of petals at least partially define a circumference of the device, the circumference between 10 mm and 20 mm,each of the plurality of petals has a circumferential width between 20° and

    30°

    ,each of the plurality of petals is spaced from an adjacent petal by a circumferential gap width between 20° and

    30°

    , anda thickness of the device except the refractive optic is between 0.1 mm and 0.5 mm,the device capable of being rolled into a folded state for insertion in a natural capsular bag of an eye, andthe device capable of transforming from the folded state to a capsular state upon insertion in a natural capsular bag of an eye, wherein, in the capsular state;

    the plurality of petals extend anterior to the posterior end and partially curl radially inwardly,the first curved lateral side of each petal of the plurality of petals at least partially overlaps the second curved lateral side of a circumferentially adjacent petal of the plurality of petals,the plurality of petals and the posterior end at least partially define a cavity capable of containing an intraocular lens,the ends of the plurality of petals at least partially define an anterior opening capable of allowing insertion of an intraocular lens, andthe plurality of petals and posterior end of the device at least partially define a circumferential housing structure comprising capsular bag-contacting surfaces.
