- Trabeculectomy creates a new drainage route for aqueous humour, aiming to reduce intraocular pressure.

Trabeculectomy creates a new drainage route for aqueous humour to reduce intraocular pressure. A flap made from the eye's own tissue helps control this outflow.

Follow-up is part of treatment
After surgery, pressure and healing are monitored at appointments. Flap sutures may need adjustment or release according to the progress of each eye. Technique and treatment details are individualised.
The aim is to preserve existing vision. Medication or additional treatments may still be necessary.
