- a prosthetic capsular device, the prosthetic capsular device comprising;
a housing structure capable of containing an intraocular lens (IOL), the housing structure including;
a first lateral side including;
a first end, anda second end;
a second lateral side opposite the first lateral side, the second lateral side including;
a first end, anda second end;
a third lateral side extending between the first end of the first lateral side and the first end of the second lateral side;
a fourth lateral side extending between the second end of the first lateral side and the second end of the second lateral side;
a posterior side including a posterior refractive optic;
an anterior side opposite the posterior side, the anterior side including an opening configured to allow insertion of a medicament delivery device; and
wherein the first lateral side, the second lateral side, the third lateral side, the fourth lateral side, the posterior side, and the anterior side of the housing structure at least partially defining a cavity and comprising capsular bag-contacting surfaces, the cavity of the housing structure capable of containing a medicament delivery device; and
a medicament delivery device, the medicament delivery device comprising;
an anterior side;
a posterior side;
a framework comprising a flexible material capable of reverting to an original shape upon insertion in a cavity of a prosthetic capsular device in an eye, the framework comprising a ring proximate to the anterior side, the ring comprising;
a first portion, the first portion including;
a first end, anda second end,a second portion, the second portion including;
a first end, anda second end,a third portion extending between the first end of the first portion and the first end of the second portion, anda fourth portion extending between the second end of the first portion and the second end of the second portion,at least one of the first portion, the second portion, the third portion, and the fourth portion comprising a break in the flexible material;
a first medicament cage coupled to at least the third portion of the framework, the first cage extending between the anterior side of the framework and the posterior side of the framework, the first cage configured to contain a first medicament, the first cage comprising a mesh structure configured to allow the first medicament to interact with anterior chamber fluid of an eye; and
a second medicament cage coupled to at least the fourth portion of the framework, the second cage extending between the anterior side of the framework and the posterior side of the framework, the second cage configured to contain a second medicament, the second cage comprising a mesh structure configured to allow the second medicament to interact with anterior chamber fluid of an eye,the medicament delivery device configured to be inserted into said cavity of the prosthetic capsular device,the cavity of the prosthetic capsular device having a lateral shape corresponding to a lateral shape of the framework,wherein the medicament delivery device is configured to be radially outward of a visual axis of the posterior refractive optic upon insertion of the medicament delivery device in the cavity of the prosthetic capsular device.

Abstract
A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.
