Glaucoma Tube Surgery at The Eye Doctor Clinic
Also known as Tube Shunt or Glaucoma Drainage Device Surgery
Also known as Tube Shunt or Glaucoma Drainage Device Surgery, aqueous shunt implants divert fluid from inside the eye to a reservoir beneath the eyelid, providing reliable long-term pressure control for advanced or complex glaucoma when other treatments are not enough.

What a great experience! Very reassuring and I am very grateful for the consultation from Dr Musa he was so helpful in helping me make a decision to proceed to having eye correction surgery. I have the upmost confidence in him and the team at the Eye Doctor Clinic, Huddersfield.
Lozza 747I had implants with Dr Musa ten years ago. It was the best thing I've ever done. They are brilliant. My sight both near and distant was very poor but since the op I've had no glasses no lenses and my sight has been super. It remains really good to this day. Thank you Dr Musa. Brilliant consultations and treatment for glaucoma since.
Kay FitbitI can highly recommend the Eye Doctor Clinic, and I am so pleased I went there. Dr Musa, Gemma and Jess are lovely. They are very knowledgeable and were able to answer all my questions. My vision following surgery is great, and not having to wear glasses is fantastic.
Carol PeelGlaucoma Tube Surgery
Glaucoma tube surgery is an advanced surgical treatment used when other glaucoma procedures are unlikely to succeed or have already failed. It is particularly effective in complex or high-risk glaucoma cases.
The procedure involves implanting a small drainage tube connected to a reservoir plate to divert fluid out of the eye safely and lower intraocular pressure.
Tube surgery provides reliable pressure control in challenging glaucoma cases.

How Glaucoma Tube Surgery Works
A small flexible tube is placed inside the eye and connected to a plate positioned on the outer surface of the eye, hidden beneath the eyelid.
Fluid drains through the tube to the plate, where it is absorbed gradually by surrounding tissue. This controlled drainage lowers eye pressure without relying on the eye's natural drainage system.
The design allows predictable and sustained pressure reduction.
Tube Implantation at a Glance
- Condition: Complex or refractory glaucoma
- Goal: Long-term IOP reduction
- Device: Silicone tube & plate (e.g. Ahmed, Baerveldt)
- Anaesthesia: Local with sedation
- Duration: 60–90 minutes
- Stay: Day case — home same day
- Recovery: 4–6 weeks to full activity
- Success: ~85% IOP control at 5 years
The Procedure
Pre-Operative Assessment
Your consultant performs a comprehensive glaucoma assessment including intraocular pressure measurement, optic nerve imaging, and visual field testing to confirm tube implantation is the most appropriate surgical option for your glaucoma.
Anaesthesia
The procedure is carried out under local anaesthesia with sedation, or occasionally general anaesthesia. Numbing injections around the eye ensure you are comfortable and feel no pain throughout the operation.
Plate Fixation
A small silicone plate (the reservoir) is carefully secured to the outer wall of the eye (sclera), typically in the upper outer quadrant. This plate acts as a bleb — a pocket that collects the fluid drained from the eye.
Tube Insertion
A fine flexible silicone tube is threaded through the eye wall and positioned inside the anterior chamber, just in front of the iris. This tube creates a new permanent drainage pathway for aqueous humour to flow from inside the eye to the plate.
Tube Coverage
A small patch graft — usually donor sclera or pericardium — is sutured over the tube where it enters the eye wall. This protects the tube and prevents erosion through the overlying conjunctiva.
Closure & Recovery
The conjunctiva is carefully closed over the plate and tube. Antibiotic and anti-inflammatory drops are prescribed and you will be monitored closely in the weeks following surgery for pressure and healing.
Key Benefits
Conditions Treated with Glaucoma Tube Surgery
Tube surgery is commonly used to treat:
- Advanced or refractory glaucoma
- Glaucoma following previous failed surgery
- Neovascular glaucoma
- Uveitic glaucoma
- Glaucoma associated with scarring risk
It is often chosen when trabeculectomy is unlikely to succeed.
Safety & Success Rates
Glaucoma tube surgery has strong long-term success rates, particularly in complex glaucoma. Complications are uncommon when surgery is performed by experienced glaucoma surgeons with appropriate follow-up.
Preserving Vision & Quality of Life
By controlling eye pressure in difficult glaucoma cases, tube surgery can preserve remaining vision and help maintain independence and quality of life.
What to Expect
Glaucoma tube surgery is typically performed under local anaesthetic as a day case. Vision may be blurred initially and stabilises gradually. Follow-up appointments are essential to monitor eye pressure and ensure the tube is functioning correctly.
Eye pad worn initially. Vision blurred. Steroid and antibiotic drops started. Avoid bending, lifting, or straining.
Vision gradually improving. Pressure monitored closely at clinic visits. Drops continued. Avoid contact sports and swimming.
IOP usually stabilising as the bleb matures around the plate. Drop regimen reviewed and often reduced.
Pressure typically at its stable target range. Vision consolidating. Most activity restrictions lifted.
Long-term IOP control established. Regular monitoring continues to ensure the implant remains effective.
Annual or bi-annual glaucoma reviews to check pressure, optic nerve, and visual fields. Implants can last many years.
Avoid rubbing your eye, swimming, and contact sports during recovery. Attend all follow-up appointments so your consultant can monitor your intraocular pressure and implant function.
Tube Implantation FAQs
Tube implantation (also called glaucoma drainage device surgery or aqueous shunt surgery) involves placing a small silicone tube into the eye to create a permanent new drainage channel. Aqueous humour flows through the tube to a small plate fixed to the outer wall of the eye, where it is absorbed by surrounding tissues, lowering intraocular pressure.
Tube implantation is typically recommended for patients with complex or refractory glaucoma — those whose pressure is uncontrolled despite maximum medical therapy, those who have had a failed trabeculectomy, those with certain types of secondary glaucoma (such as neovascular or uveitic glaucoma), or those at high risk of trabeculectomy failure due to previous eye surgery or scarring.
Trabeculectomy creates a drainage bleb directly in the conjunctiva without a device. Tube implantation uses a silicone tube connected to a plate to drain fluid. Tube implantation tends to be preferred in more complex cases where trabeculectomy is less likely to succeed, or when previous trabeculectomy has failed. Both aim to lower IOP but involve different surgical techniques and recovery profiles.
As with all eye surgery, risks include infection, bleeding, and vision changes. Specific risks include hypotony (pressure too low), diplopia (double vision) if the tube affects eye movement, tube erosion through the conjunctiva, and in rare cases loss of vision. Your consultant will discuss all risks in detail at your pre-operative consultation.
Tube implants are designed as permanent devices. Studies show approximately 85% of patients maintain adequate IOP control at five years. Long-term efficacy is well documented, though some patients may still require supplementary eye drops or further intervention over time.
