Trabeculectomy is a glaucoma operation that creates a new drainage channel to lower eye pressure and protect sight.
Why trabeculectomy is recommended
Glaucoma damages the optic nerve when pressure in the eye stays too high, even with drops, tablets, or laser treatment.
Trabeculectomy offers a stronger, longer lasting pressure reduction by allowing fluid to leave the eye under a small flap in the white of the eye.
- Considered when other treatments are no longer enough to keep pressure safe
- Suitable for many types of glaucoma, including advanced open angle disease
- Aims to slow or halt further sight loss rather than restore lost vision
- Requires careful follow up to fine tune healing and pressure
What happens during and after surgery
The surgeon fashions a tiny trapdoor in the white coat of the eye and creates a new channel for fluid to drain into a small blister bleb hidden under the upper eyelid.
Recovery is gradual, and you will use several drops and attend frequent checks while the eye settles.
- Expect redness, blurred vision, and light sensitivity for several weeks
- Stitches or laser adjustments may be needed to balance drainage
- Avoid rubbing, heavy lifting, and swimming until your specialist advises
- Report increasing pain, sudden blur, or discharge straight away
