IOL with drug delivery devices and uninterrupted PCO barrier edge

摘要

An ophthalmic implant comprising an intraocular (IOL) assembly comprising a lens 24, and a haptic 28, said IOL assembly characterised by an anterior surface 24A and a posterior surface 24P, and a circumferential side walls 24C, wherein the posterior surface joins the circumferential side a wall in a sharply angular edge 24E. The sharply angular edge 24E defining a plane P of the sharply angular edge 24E. A drug delivery device 30 disposed on the haptic 28, the drug delivery device 30 configured and disposed on the haptic 28 such that a posterior most surface 30P of the drug delivery device 30 is anteriorly displaced from the plane P, whereby the presence of the drug delivery device 30 on the haptic 28 does not disrupt the formation of a posterior capsular opacification (PCO) barrier. In another aspect, the drug delivery device may have a posterior surface (33P, Figure 8), and a circumferential side wall (33C, Figure 8), wherein the posterior surface joins the circumferential side wall in a sharply angular edge (33E, Figure 8).
