PROSTHETIC CAPSULAR DEVICES, SYSTEMS, AND METHODS

摘要

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.

主权项

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;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;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; anda 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; anda 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.
