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.
