Abstract
An ophthalmic implant including an IOL with haptics, and drug delivery devices secured to the haptics. The posterior-most extent of the drug delivery device is located anterior to the posterior edge or PCE barrier edge, of the IOL. In other configurations, the drug delivery devices are provided with PCO barrier edges.
Claims20
An ophthalmic implant comprising:
- an intraocular lens (IOL) comprising an anterior side, a posterior side opposite the anterior side, a lens, a circumferential side wall circumscribing the lens, and a haptic coupled to and extending outwards from the circumferential side wall;
- and
- a drug delivery device comprising a posterior panel comprising a posterior panel side wall, an anterior panel comprising an anterior panel side wall, a pair of posts joining the posterior panel and the anterior panel, and an aperture bounded by the posterior panel, the anterior panel, and the pair of posts, wherein the haptic is configured to be received within the aperture of the drug delivery device such that:
- at least a portion of the posterior panel side wall lies adjacent the circumferential side wall of the IOL;
- and at least a portion of the anterior panel side wall protrudes inward of the circumferential side wall of the IOL on the anterior side of the IOL.
