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 housing structure capable of containing an intraocular lens (IOL), the housing structure including;

    a first flat lateral side, the first flat side including;

    a first end, anda second end;

    a second flat lateral side opposite the first flat lateral side, the second flat lateral side including;

    a first end, anda second end;

    a third arcuate lateral side extending between the first end of the first flat lateral side and the first end of the second flat lateral side, the third arcuate lateral side comprising a capsular bag-contacting surface;

    a fourth arcuate lateral side extending between the second end of the first flat lateral side and the second end of the second flat lateral side, the fourth arcuate lateral side opposite the third arcuate lateral side, the fourth arcuate lateral side comprising a capsular bag-contacting surface;

    a posterior side including a refractive surface;

    an anterior side opposite the posterior side, the anterior side including an opening configured to allow insertion of an intraocular lens and a lip formed around the opening; and

    a longitudinal axis,the first flat lateral side, the second flat lateral side, the third arcuate lateral side, the fourth arcuate lateral side, the posterior side, and the anterior side at least partially defining a cavity, the cavity of the housing structure capable of containing an intraocular lens; and

    a ring structure including;

    a first ring structure portion extending from proximate to the first end of the first flat lateral side radially outward and towards the second end of the first flat lateral side, the first ring structure portion comprising a capsular-bag contacting surface; and

    a second ring structure portion extending from proximate to the second end of the second flat lateral side radially outward and towards the first end of the second flat lateral side, the second ring structure portion comprising a capsular-bag contacting surface,wherein the first ring structure portion includes an anchor comprising a first anchor portion that extends a distance along the first flat lateral side and a second anchor portion that extends a distance along the third arcuate lateral side, the anchor of the first ring structure portion being embedded within the housing structure;

    wherein the second ring structure portion includes an anchor comprising a first anchor portion that extends a distance along the second flat lateral side and a second anchor portion that extends a distance along the fourth arcuate lateral side, the anchor of the second ring structure portion being embedded within the housing structure; and

    wherein each of the first ring structure portion and the second ring structure portion includes an anterior-posterior opening proximate to a terminal end.
