Abstract

A therapeutic system comprises an ocular insert placed on a region outside an optical zone of an eye. The ocular insert comprises two structures: a first skeletal structure and a second cushioning structure. The first structure functions as a skeletal frame which maintains positioning of the implant along the anterior portion of the eye and provides support to the second, cushioning structure. This first structure maintains the attachment of the therapeutic system to the anterior portion of the eye for at least thirty days. In some embodiments the first structure remains a constant size and shape, e.g. a ring shape, a ring with haptics, or a curvilinear ring that is confined to and restrainingly engages the inferior and superior conjunctival fornices so as to retain the implant within the tear fluid and/or against the tissues of the eye.
