Glaucoma Drainage Devices (Tube Shunt Surgery) in the Philippines
Overview of Tube Shunt Surgery
Glaucoma drainage devices (also known as tube shunt implants) are surgical options for patients whose glaucoma is not controlled by medications or laser treatments. The procedure involves implanting a small device in the eye to help drain excess aqueous fluid, reducing intraocular pressure (IOP) and preventing further damage to the optic nerve.
This method is generally recommended for advanced glaucoma cases or those who have had previous unsuccessful surgeries, such as trabeculectomy.
How the Procedure Works
The surgeon implants a tiny tube, connected to a plate, inside the eye. The tube allows fluid to flow from the eye to a small reservoir placed under the conjunctiva, where it is absorbed by the surrounding tissues. By controlling fluid drainage, the device helps maintain lower eye pressure.
Commonly used tube shunts include:
-
Ahmed Glaucoma Valve
-
Baerveldt Glaucoma Implant
-
Molteno Implant
Benefits of Tube Shunt Surgery
-
Effective for severe or resistant glaucoma
-
Reduces eye pressure when medications and other surgeries fail
-
Long-term solution for pressure control
-
Can be performed on eyes with previous failed surgeries
Risks and Considerations
Like all surgeries, tube shunt implantation has potential complications:
-
Double vision
-
Tube blockage or migration
-
Hypotony (eye pressure too low)
-
Infection or inflammation
Close follow-up with an ophthalmologist is essential to monitor healing and pressure control.
Availability in the Philippines
Is tube shunt surgery available in the Philippines?
Yes, but it is not as widely offered as standard glaucoma procedures like trabeculectomy or laser treatment. Major hospitals and specialized eye centers in Metro Manila, Cebu, and Davao usually provide this option for advanced cases. However, availability may vary, and costs can differ significantly depending on the implant type and hospital.

Cost of Glaucoma Drainage Devices in the Philippines
The cost of tube shunt surgery depends on several factors:
-
Type of implant (Ahmed, Baerveldt, etc.)
-
Surgeon’s expertise
-
Hospital facility fees
In the Philippines, the price can range from ₱80,000 to ₱150,000 or more, depending on the device and hospital charges.
Who Should Consider This Surgery?
Tube shunt surgery is usually recommended for:
-
Patients with uncontrolled glaucoma despite medications and prior surgeries
-
Eyes with significant scarring from previous operations
-
Patients with secondary glaucoma (such as neovascular glaucoma)
Recovery and Follow-Up Care
-
Most patients require close follow-up visits for several weeks after surgery.
-
Eye drops may be prescribed to reduce inflammation and prevent infection.
-
Vision may be blurry for a few weeks, but this usually improves over time.
