Information for the public

There is not enough evidence about how well this procedure works long term. So it can only be done with special arrangements. This means you will have regular appointments afterwards to check how well it is working or if it has caused problems.

Open-angle glaucoma is a progressive condition that causes increased pressure in the eye. This damages the nerve that connects the eye to the brain and may lead to permanent sight loss. This procedure involves making a small cut in the eye (ab interno) and inserting a tiny tube into the channel that drains fluid from the eye. The tube widens the drainage channel (canaloplasty), then gel is injected into it and the tube is removed. The gel keeps the channel wider for a few days then dissolves, leaving the channel permanently wider to allow excess fluid to drain away. The aim is to reduce pressure in the eye. The NHS website may have information on your condition and treatment options.

You can search the NHS website for information about consultants and hospitals that offer this procedure.
