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 Trabeculectomy is usually done under local anaesthetic. It involves creating a conjunctival opening to access the sclera, followed by the formation of a partial-thickness scleral flap. Within the scleral bed a full-thickness opening is created into the anterior chamber, to enable drainage of aqueous. The scleral flap is then sutured loosely with 1 or 2 loops, to allow the aqueous fluid to drain. Cohesive viscoelastic is injected under the scleral flap. Then a subconjunctival biodegradable collagen matric implant is placed directly on top of the scleral flap, and the conjunctiva is sutured (using continuous sutures) and closed around it.
