NICE has been notified about this procedure and it is part of its work programme. The Interventional Procedures Advisory Committee (IPAC) will consider this procedure and NICE will issue an interventional procedures consultation document about its safety and efficacy for 4 weeks’ public consultation. IPAC will then review the consultation document in the light of comments received and produce a final interventional procedures document, which will be considered by NICE before guidance is issued to the NHS in England, Wales, Scotland and Northern Ireland.

Description Artificial iris implants can be solid acrylic rings or segments, or flexible silicone discs. The silicone discs are available in standard colours or custom-made for each patient. The implant has a defined pupil size, which offers a compromise between day and night vision. The artificial iris implant is inserted under local or general anaesthesia. The exact details of the procedure vary according to the type of implant being used. Flexible implants are rolled up and inserted through a cut about 3 mm long at the edge of the cornea, into the posterior chamber of the eye. They are then unfolded and fixed in the eye. If sutures are needed to hold the implant in place, a larger cut may be necessary. The implant insertion can be done on its own or at the time of cataract or lens fixation surgery. Solid ring implants are typically inserted during cataract surgery along with an intraocular lens. In some patients, an iris reconstruction lens containing both an artificial iris and a lens is implanted. Depending on the condition of the eye, the lens and iris device may need to be sutured to the sclera. The aim of artificial iris implant insertion is to improve visual acuity, reduce photophobia and glare, and improve the eye’s appearance.
