Trabeculectomy is a glaucoma operation that creates a new drainage channel to lower eye pressure. Knowing the steps can make the process feel less daunting.
During the operation
The surgery is usually done under local anaesthetic with sedation so you stay comfortable. The surgeon forms a controlled opening in the white of the eye.
- A small flap is fashioned under the upper eyelid to regulate flow
- Fluid drains into a tiny reservoir called a bleb beneath the conjunctiva
- Anti-scarring medicines may be applied to keep the channel open
- Fine stitches adjust how much fluid can leave the eye
Immediate aftercare and early healing
Close follow-up is essential in the first weeks. Pressure and bleb appearance guide drop changes and possible stitch adjustments.
- Steroid and antibiotic drops help control inflammation and infection
- Activity restrictions reduce the risk of bleeding or trauma
- Some blur, redness, and foreign-body sensation are common initially
- Extra clinic visits may be needed to tweak stitches or perform gentle massage
