Glaucoma Surgery (Trabeculectomy & Valve Implants)
When glaucoma cannot be controlled with drops or laser treatment, surgery may be necessary to prevent permanent vision loss.
At Woolfson Eye Institute, serving patients in Atlanta, Sandy Springs, and throughout Metro Atlanta, we provide advanced glaucoma surgery — including trabeculectomy and glaucoma valve implants — to lower eye pressure and protect the optic nerve, especially for patients with diabetes who may have complex glaucoma.

What Is Glaucoma Surgery?
Glaucoma surgery is performed when eye pressure (intraocular pressure or IOP) remains too high despite medications or laser therapy.
The goal of surgery is to:
- Create a new drainage pathway
- Improve fluid outflow
- Lower eye pressure
- Protect the optic nerve from further damage
Two common surgical procedures include:
Trabeculectomy
Creates a small drainage opening in the eye to allow fluid to exit more efficiently.
Glaucoma Valve Implants (Tube Shunts)
Places a small drainage device inside the eye to redirect fluid flow.
What Types of Diabetic Eye Conditions Does It Treat?
Patients with diabetes may require glaucoma surgery for:
Advanced Primary Open-Angle Glaucoma
Often more aggressive in diabetic patients.
Neovascular Glaucoma
A serious complication of advanced diabetic retinopathy involving abnormal blood vessel growth.
Secondary Glaucoma
Due to inflammation, bleeding, or retinal disease.
Uncontrolled Ocular Hypertension
When pressure remains dangerously high.
In complex diabetic cases, surgery may be critical to preserving remaining vision.
How Does Trabeculectomy Work?
During trabeculectomy:
- A small flap is created in the sclera (white of the eye).
- A new drainage channel allows fluid to flow out.
- Fluid collects in a small reservoir (bleb) under the eyelid.
- Eye pressure gradually decreases.
This procedure creates a permanent alternative drainage pathway.
How Do Glaucoma Valve Implants Work?
With a valve implant:
- A tiny tube is inserted into the front of the eye.
- The tube connects to a small plate placed under the conjunctiva.
- Fluid drains through the tube and is absorbed naturally.
- Pressure stabilizes at a safer level.
Valve implants are often preferred in complex or diabetic-related glaucoma cases.
Benefits for Patients
Glaucoma surgery can:
✔ Significantly lower eye pressure
✔ Prevent further optic nerve damage
✔ Reduce or eliminate need for multiple drops
✔ Protect remaining vision
✔ Stabilize advanced glaucoma
For diabetic patients with neovascular glaucoma, surgery can be vision-saving.
What Can Patients Expect During Surgery?
Glaucoma surgery is typically:
- Performed in an outpatient surgical center
- Done under local anesthesia with sedation
- Completed in about 45–90 minutes
After surgery:
- A protective shield is placed over the eye
- Vision may be blurry initially
- Follow-up visits begin within 1–2 days
Recovery & Aftercare
Recovery varies but generally includes:
- Several weeks of healing
- Frequent follow-up visits
- Anti-inflammatory and antibiotic drops
- Avoiding heavy lifting temporarily
- Monitoring eye pressure closely
Diabetic patients require careful retinal monitoring during recovery.
Potential Side Effects
Possible side effects include:
- Temporary blurred vision
- Eye redness
- Light sensitivity
- Mild discomfort
More serious but less common risks include:
- Infection
- Low eye pressure (hypotony)
- Scarring of the drainage site
- Bleeding
- Need for additional surgery
Close follow-up helps detect and manage complications early.
Risks & Considerations
Important considerations:
- Surgery does not restore lost vision
- It prevents further damage
- Healing may take weeks to months
- Diabetic patients may have higher healing variability
- Lifelong monitoring remains necessary
Our skilled, trained ophthalmologists will carefully evaluate your individual risk profile.
How to Prepare for Glaucoma Surgery
Before surgery:
- Complete a comprehensive glaucoma evaluation
- Undergo retinal imaging
- Stabilize blood sugar levels
- Review current medications
- Arrange transportation
After surgery:
- Follow all drop instructions
- Attend scheduled follow-ups
- Avoid rubbing your eye
- Monitor for unusual symptoms
Preparation and compliance improve outcomes.
When Is Glaucoma Surgery Recommended?
You may need surgery if:
- Eye pressure remains high despite medication
- Glaucoma continues to progress
- Vision is at risk
- Neovascular glaucoma develops
- You cannot tolerate glaucoma drops

Frequently Asked Questions
Is glaucoma surgery painful?
No. It is performed with anesthesia and most discomfort is mild afterward.
Will surgery cure glaucoma?
No. It controls pressure but does not cure the disease.
How long does recovery take?
Initial healing takes weeks, with full stabilization over several months.
Is surgery safe for diabetic patients?
Yes, but careful monitoring is essential due to increased complication risk.
Is it covered by insurance?
When medically necessary, glaucoma surgery is typically covered.
