ATTACHMENT STRUCTURE PROSTHETIC CAPSULAR DEVICES

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.
