Ophthalmic Implants, Symblepharon Ring

Definition : Convex-shaped rings that are fitted in the anterior eye socket over the eye globe to prevent adhesions and shortening or retraction of the fornices. Symblepharon rings are usually made of plastic (e.g., polymethylmethacrylate) with highly polished edges to prevent trauma to the eye; they may come in various sizes (e.g., small [20 mm], medium [22 mm] and large [24 mm]). Symblepharon rings (also known as open fornices conformers) are implanted without touching the cornea, helping to reduce scarring by keeping the eyelids way from an irritated eye. They are intended to maintain ocular fornices after surgery in situations where conjunctival cicatricial disease is present, or after ocular trauma such as chemical burns or avulsion of the conjunctiva. In the case of surgery or trauma, they should be inserted as soon as possible to prevent adhesions and/or shortening of the fornices and cul-de-sacs. Some rings may be used over prosthetic eyeballs.
