Questions about Trabeculectomy

Trabeculectomy is a traditional eye surgery approach to treating glaucoma. The procedure aims to lower the eye pressure to help prevent your glaucoma worsening and further loss of vision.

Why, and when, do I need trabeculectomy?

Because there are some risks associated with surgery, trabeculectomy is reserved for people who are at high risk of their glaucoma worsening and vision loss. Usually, this is after other glaucoma treatments, such as eye drop treatments and/or laser treatments, have not been successful. It may be needed after less invasive, but less effective glaucoma surgery (sometimes called minimally invasive glaucoma surgery – MIGS).

It may be recommended when there is very high eye pressure which cannot be controlled with less invasive treatments, and there is a very high risk of losing vision from glaucoma – even before substantial vision loss. There is also evidence that it can be a reasonable first line of treatment for people who already have severe glaucoma when they are first diagnosed.
