Tube shunt surgery, also called glaucoma shunt procedure, aqueous shunt surgery, or glaucoma drainage valve implantation, is an advanced type of glaucoma surgery. In this procedure, a small tube-like device is implanted in the eye to help drain excess fluid and lower intraocular pressure (IOP).
This surgery is usually recommended for patients with advanced glaucoma where medicines or standard surgeries like trabeculectomy have failed. Glaucoma tube shunt surgery helps prevent further vision loss, although it cannot restore vision that is already lost.
How Tube Shunt Surgery Works – Step by Step
- A tiny silicone tube is inserted into the front part of the eye.
- This tube is connected to a plate that sits on the surface of the eye, beneath the conjunctiva.
- The excess eye fluid (aqueous humor) drains through the tube to the plate, where it is absorbed gradually.
- This drainage process helps equalize eye pressure with outside pressure, reducing the risk of optic nerve damage.
The entire tube shunt eye surgery is usually performed under local anesthesia and takes about 45–60 minutes.
Tube Shunt Surgery Success Rate & Effectiveness
- The tube shunt surgery success rate is high in patients who have uncontrolled glaucoma despite maximum medical or surgical treatment.
- Modern devices like the Ahmed Glaucoma Valve include internal valves that prevent over-drainage, making the results more predictable.
- While it may require longer post-operative care compared to trabeculectomy, it offers effective long-term control of IOP.
What Are the Types of Glaucoma Tube Shunt Surgery?
- Tubes (Ahmed Glaucoma Valve and similar devices):
- A tube with a plate drains fluid from inside to outside the eye.
- Advanced tubes with valves prevent over-drainage and keep pressure stable.
- Stents:
- Microscopic devices placed inside the eye’s drainage channels.
- Help fluid bypass blocked drainage but do not connect outside the eye.
- Widely used in the West, but costly.
- Biomedical Tissue Implants (Xen Gel Implant):
- A collagen-based tube, 6 mm long, inserted inside the eye.
- Still in the research phase in India.
Risks & Complications of Tube Shunt Surgery
Like any eye surgery, glaucoma shunt surgery has risks, such as:
- Pain and irritation due to sutures.
- Eye pressure fluctuations – very low pressure (hypotony) in the first week or high pressure later (hypertonic phase).
- Risk of infection (rare but serious).
- Need for long-term follow-up and sometimes continued eye drops.
Recovery & Aftercare After Tube Shunt Surgery
- Maintain strict hygiene – avoid touching or rubbing the eye.
- Do not let water enter the eye for 2 weeks.
- Use sterile cotton to clean the eye.
- Take prescribed medications regularly.
- Avoid heavy lifting, bending forward, or applying pressure on the operated eye.
What to expect after surgery:
- Day 1–7: Pain, irritation, and low pressure (hypotonic phase).
- Day 7–60: Eye pressure may rise (hypertonic phase) but can be controlled with eye drops.
- Gradual stabilization after 2 months.
Tube Shunt Surgery Cost in India
The tube shunt surgery cost in India depends on the device used and hospital facilities. On average, it ranges from ₹50,000 – ₹80,000 per eye, including the cost of the valve (e.g., Ahmed Glaucoma Valve).
At Eye Solutions, patients benefit from all-inclusive packages covering post-surgery visits for up to two months.

- Glaucoma after blunt eye trauma.

Hear from Our Happy Patients
I had an exceptional experience at Eye Solutions! Their facility is equipped with the latest machines and technologies. The team of doctors is outstanding, and I was particularly impressed with Dr. Urmi, who conducted my comprehensive eye checkup, and Dr. Kartik, who performed the eye pressure and glaucoma testing. I highly recommend their services - the team is skilled, knowledgeable, and well-equipped.
Almost 9 months ago I had almost lost vision of my left eye.
I was treated by an eye surgeon for Glucoma, (3 injections in my eye) by an eye surgeon but to no avail.
At this time, I consulted Dr. DEEPAK GARG. I was fortunate to contact him. It was a blessing in disguise because I have completely recovered, after his treatment.
HE HAS A MIDAS TOUCH.
I was administered 3 injections in left eye and also underwent cataract surgery in both eyes.
Within 3 months not only did I regain my vision, in both eyes but also spent much, much less than what I did for the previous 3 injections.
Now I can read newspsper without glasses.
God has blessed Dr. Garg because
- He is Humble (down to earth attitude)
- very concerned and very helpful
- not in the lease money minded.
- Dr Garg & his whole team is very amicable and creats a pleasant atmosphere once you walk Into their clinic.
I highly recommend Dr. Deepak Garg, from the bottom of my heart. He is a wonderful eye surgeon.
HE IS TRUELY A DOCTOR IN SIGHT
I had cataract surgery on both eyes, earlier this year at Eye Solutions.
I cannot recommend more highly, Dr. Garg, Shashi Ramchandra and the entire staff for their professionalism, care and attentive postoperative follow up.
Many thanks to all at this superb establishment.
We have been visiting Eye Solution for the past six years for the annual eye check-up of our special child, and I felt it was finally time to write this review.
Every visit has reassured us that we chose the right place. My child is not always very cooperative during eye examinations, which can make the process challenging. However, the doctors (Dr Deepak Garg) and staff here have consistently shown immense patience, understanding, and kindness. They never rush, never show frustration, and always create a calm and reassuring environment for him.
Over the years, we have seen the same level of dedication and professionalism. The atmosphere is comfortable, child-friendly, and supportive — something that truly matters to parents like us.
If you are looking for an eye hospital where your child, especially a special child, will be treated with care, patience, and respect, I would strongly recommend Eye Solution. It has been a dependable and compassionate place for our family for six years.
I underwent cataract surgery with Dr Deepak Garg on four eyes - two of mine, obviously, and two of my sister. Each procedure was smooth, painless and professionally handled. Dr Garg explains the process calmly and executes it with precision. Equally impressive is his staff - helpful, courteous and efficient. Highly recommended
⭐️⭐️⭐️⭐️⭐️
I had a fantastic experience with Urmi Shah at Eye Solutions. They are truly reliable and knowledgeable eye care specialists who clearly know what they’re doing. I reached out for a last-minute appointment and was impressed by how accommodating and efficient the team was. Their honesty, professionalism, and cost-effective services make them stand out. What really sets them apart is their exceptional follow-up and customer service. They genuinely care about their patients. Highly recommended for anyone seeking trustworthy and affordable eye care!
Dr Urmi is a technically sound, empathetic and fine doctor. My father recently underwent cataract surgery, and we couldn’t be more pleased with the experience. From the initial consultation to the post-operative care, the entire process was smooth and professional. Dr Urmi was incredibly kind, patient, and took the time to explain everything in detail, which really helped put us at ease.
The staff was also courteous, efficient, and made sure all our questions were answered. I highly recommend Dr Urmi to anyone considering cataract surgery.
Dr Deepak Garg and his team handling customer timely and effectively
Dr Urmi Shah is a excellent Doctor. She treated my brother in law, brother for their cataract and also my daughter's dry eye infection. She and her staff are very cooperative and make the patient feel comfortable.
I had my mother treated for swelling in her retina by Dr Urmi Shah. She is highly skilled and experienced. My mother is very happy and satisfied with Dr Urmi's treatment. I very strongly recommend Dr Urmi Shah, for she's a good ophthalmologist.
Absolutely fantastic experience. Professional, and exceptional in IT enablement
I had a grt experience here ..
Doc Urmi is very good with her diagnosis and the staff is also very polite ....recommend everyone to go to her !!
