Glaucoma Shunt / Tube Surgery in Mumbai – Kurla BKC, Kalina & Bandra W

When trabeculectomy has failed or is unlikely to succeed due to scarring, a glaucoma drainage device (shunt or tube) provides an alternative pathway for fluid to exit the eye. It is a highly effective option for complex glaucoma cases that have resisted other treatments.

What Is Glaucoma Shunt / Tube Surgery?

A small silicone tube is inserted into the eye and connected to a plate fixed to the outer wall of the eye. Fluid drains through the tube to the plate, where it is absorbed. Devices such as the Ahmed Glaucoma Valve include a pressure-sensitive valve to prevent over-drainage.

Who Is It For?

This procedure is generally suited to patients meeting the following criteria:

Failed previous trabeculectomy
Neovascular, uveitic, or traumatic glaucoma
Eyes with excessive scarring making filtration surgery difficult
Certain paediatric glaucoma cases

What Happens During the Procedure?

Each step is performed with precision and patient comfort in mind.

Step 1: General or peribulbar anaesthesia
Step 2: Plate sewn to the outer surface of the eye behind the lid
Step 3: Tube inserted into the anterior chamber through a small incision
Step 4: Tube covered with donor tissue or a patch graft for protection

Recovery & What to Expect

A temporary pressure rise may occur in the first 4–6 weeks while the drainage capsule matures. Pressure-lowering drops may be needed during this period. Full pressure control is usually achieved by 6–8 weeks post-operatively.

Benefits

Patients choosing this procedure typically experience the following benefits:

Effective for complex glaucoma where trabeculectomy is not suitable
The valve mechanism prevents dangerous pressure drops
Long-lasting device — no need for frequent replacement

FAQFrequently Asked Questions

Is a glaucoma shunt permanent?

Yes — the device remains in the eye permanently. It is made of biocompatible materials and is well tolerated long-term.

Can I feel the tube?

The tube is inside the eye and the plate is under the conjunctiva — patients typically do not feel it after healing.
