Abstract: An implantable artificial iris device which takes the form of a thin, generally annular, single-radially-split wafer, or web, of a bio-compatible, flexible material which can be colored in various ways to replicate the appearance of its predecessor, damaged natural iris. The device permits and encourages a surgical procedure which involves gentle and very simple circular threading (or snaking) of the device circularly longitudinally through a tiny slit created as an incision near the periphery of a cornea. The device is suitable for easy placement within the environment of an eye, either within the region known as the ciliary sulcus or in the region of meeting or joinder of the anterior and posterior capsules and within the realm of the capsular bag.
