| 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.

What is claimed is:
1. A single-piece artificial, implantable iris device designed for placement in a subject's eye to replace, at least partially, the natural iris in that eye, said device comprising
- an elongate, generally annular body formed of a thin expanse of an at least partially light-blocking material, and having an axis of revolution symmetry, and inner and outer, generally circular, different-radius edges, including a larger radius edge and a smaller radius edge, that generally centrally circumsurround the axis, and
- a single, generally radially disposed slit in the body extending in the body's expanse material between, and opening to, each of said edges, and defining a pair adjacent ends in said body,
- said edges, throughout their respective length, following generally substantially non-deviating circular paths, and said expanse material substantially completely spanning the area bounded by said edges and said ends.
