What happens in this surgery?

  • Involves creating a small, controlled opening in the sclera (white of the eye).
  • A tiny flap is made to allow aqueous humor to drain into a 'bleb' under the conjunctiva.
  • This new drainage system effectively reduces intraocular pressure.
  • Often performed with anti-fibrotic agents to prevent scarring and improve long-term success.

Post Surgery Recovery

What to expect after your procedure

After a trabeculectomy, patients typically experience some discomfort, redness, and blurred vision, which gradually improve over several weeks. You will be given specific instructions on how to use various eye drops, often including antibiotics and anti-inflammatory medications, which are crucial for preventing infection and controlling inflammation to ensure the success of the bleb. It is vital to adhere strictly to the eye drop regimen and attend all follow-up appointments with your ophthalmologist. During the initial recovery period, you will need to avoid strenuous activities, heavy lifting, bending, rubbing your eye, and swimming. Wearing an eye shield, especially at night, is often recommended to protect the eye. Your vision may fluctuate as the eye heals and the pressure stabilizes. Full recovery and stabilization of vision can take several weeks to a few months, during which time your doctor will closely monitor your intraocular pressure and the function of the bleb. The success of trabeculectomy depends significantly on proper post-operative care and regular monitoring. While the surgery aims to lower eye pressure and preserve vision, it cannot restore vision already lost. Long-term follow-up is essential to ensure the bleb continues to function effectively and to manage any potential complications that may arise over time.
