1541- Micro-bypass glaucoma surgery (MBGS) device implantation as a standalone procedure in patients with open-angle glaucoma (OAG)

Page last updated: 23 October 2019

Application Detail



Description of Medical Service

Micro-bypass glaucoma surgery (MBGS) devices describe a variety of ocular stents and scaffolds which, when placed in specific anatomical positions within the eye, aim to increase aqueous humour outflow, and reduce intraocular pressure. The proposed service describes the delivery of a MBGS stent which is pre-loaded on an inserter and implanted ab interno, via a corneal incision, into the trabecular meshwork or suprachoroidal space of the eye. The service is intended for individuals with primary open-angle glaucoma and is intended to be delivered as an independent procedure, not in conjunction with cataract surgery.

Description of Medical Condition

Glaucoma is a chronic degenerative optic neuropathy characterised by progressive visual field loss due to the loss of retinal ganglion cells and optic nerve damage. Primary open-angle glaucoma describes glaucoma in which disease is the primary disease of the eye with no associated conditions or diseases (primary) and the drainage channels for aqueous humour in the front of the eye appear open (open-angle.)
