Glaucoma is a serious eye condition that can gradually damage the optic nerve, often silently, leading to irreversible vision loss. One of the most effective ways to manage advanced or uncontrolled glaucoma is trabeculectomy surgery, a procedure designed to lower intraocular pressure by creating a new drainage pathway for the eye. Managing eye pressure is crucial because even slight increases over time can cause significant damage to vision.
Consulting to a trusted eye specialist is essential to assess whether trabeculectomy is the right option. An eye specialist Singapore can evaluate your individual condition, recommend the most suitable treatment plan, and guide you through the procedure safely. If you have been struggling with glaucoma or your eye pressure remains high despite medication, understanding trabeculectomy and seeking expert advice early can make a significant difference in preserving your sight.

Understanding Glaucoma and Its Risks
Glaucoma usually develops without noticeable symptoms until permanent vision loss has occurred. The condition arises when increased intraocular pressure (IOP) damages the optic nerve, the crucial link that carries visual signals from the eye to the brain. Over time, this damage can result in blind spots, and if left untreated, lead to total blindness.
There are several risk factors for glaucoma, including being over 40, having a family history of the disease, diabetes, high myopia, and persistently elevated eye pressure. In Singapore, the most common form is primary open-angle glaucoma, though angle-closure glaucoma may occur suddenly and requires urgent care. Because glaucoma damage cannot be reversed, early detection is key.
What is Trabeculectomy Surgery and How It Works?
Trabeculectomy is an eye operation for glaucoma that lowers eye pressure by creating a tiny drainage channel in the eye. This allows excess fluid to flow out, reducing pressure on the optic nerve and helping to prevent further vision loss. While the details may sound technical, understanding the key steps helps patients feel more prepared. Here’s how the procedure typically works:
- Anaesthesia – The surgery is usually performed under local anaesthesia, meaning patients remain awake but the eye is numbed to ensure comfort.
- Small incision – The eye specialist makes a tiny incision in the white part of the eye (sclera).
- Creating a drainage flap – A flap is carefully fashioned to allow excess fluid (aqueous humour) to drain out of the eye.
- Forming a reservoir – The drained fluid collects under the conjunctiva, forming a small bubble-like reservoir which is usually hidden under the upper eyelid.
- Lowering eye pressure – By redirecting fluid, the procedure reduces intraocular pressure, protecting the optic nerve from further damage.
- Duration – The surgery usually takes less than an hour, and patients can return home the same day.
An experienced eye specialist will explain each step in detail and customise the approach based on the patient’s specific eye condition.
When Trabeculectomy Surgery is Recommended
Trabeculectomy is advised when glaucoma is no longer controlled with eye drops, medication, or laser treatment. An eye specialist Singapore may recommend it if eye pressure remains high or vision continues to deteriorate. This surgery helps protect the optic nerve and prevent further vision loss when other treatments are insufficient.
Recovery and Aftercare
Recovery after trabeculectomy surgery is a gradual process that requires careful monitoring by your eye specialist. While most patients can go home the same day, proper aftercare is essential to ensure the best results. Here’s what to expect:
- Initial healing – The eye may feel slightly sore or watery for a few days. Vision can be blurred at first but usually improves as healing progresses.
- Eye drops – Special medicated eye drops are prescribed to reduce inflammation, prevent infection, and support the healing process.
- Follow-up visits – Regular check-ups are scheduled in the first few weeks so the eye specialist can monitor eye pressure and the function of the drainage flap.
- Activity restrictions – Patients are usually advised to avoid strenuous exercise, bending, or lifting heavy objects for a few weeks. Swimming should also be avoided until the eye has fully healed.
- Protective care – An eye shield may be provided to wear at night to prevent accidental rubbing or injury.
Choosing an Eye Screening Clinic in Singapore
Trabeculectomy is a safe procedure. However, like any other eye surgery, there are potential risks, including:
- Infection – Rare, but can occur if the eye is not properly cared for.
- Bleeding – Minor bleeding inside the eye may happen during or after surgery.
- Scarring – Can affect the drainage flap, possibly reducing effectiveness.
- Vision fluctuations – Temporary blurred or fluctuating vision is common.
- Low eye pressure – Sometimes pressure drops too much and requires adjustment.
An experienced eye specialist in Singapore can manage these risks and ensure the best outcome.
Conclusion
Trabeculectomy surgery is a highly effective option for managing glaucoma when other treatments are insufficient. With proper care, follow-up, and guidance from an experienced eye specialist in Singapore, patients can lower eye pressure and protect their vision from further damage. Early consultation and timely intervention are key to preserving long-term eye health.
