Before You Travel
Prepare for your Glaucoma Surgery journey
Gather Your Eye Records
Collect your glaucoma records to share with your surgeon in Thailand
- Gather records of your eye pressure readings over time — your Thai surgeon needs this to plan the right procedure
- Bring any visual field test results showing how your peripheral vision has changed over time
- Collect previous OCT scans of your optic nerve — these can also be repeated at your hospital in Thailand if needed
- List all current eye drops and any past glaucoma medications, including what worked and what didn't
- Note any previous eye surgeries or laser treatments, including dates and outcomes
Arrange Follow-Up Care at Home
Glaucoma requires lifelong monitoring — arrange ongoing care with a doctor at home before you travel
- Identify a glaucoma specialist or ophthalmologist at home who will monitor your eye pressure and vision long-term
- Discuss your surgery plans with your home eye doctor and ask for any referral notes or supporting records
- Review any blood thinners or other medications with your home doctor — they will advise if any changes are needed before surgery
- Continue your current eye drops exactly as prescribed — do not stop without your doctor's advice
- Plan your return travel carefully: trabeculectomy and tube shunt patients typically need 2-4 weeks in Thailand before flying home
Virtual Consultation with Your Thai Surgeon
Connect with your surgeon in Thailand to review your records and confirm your treatment plan
- Share your eye pressure history, visual field tests, and OCT scans ahead of your video call
- Confirm which type of glaucoma surgery is recommended for your situation (laser, MIGS, or traditional surgery)
- Ask about diagnostic tests done at the hospital in Thailand — such as corneal thickness and drainage angle assessment
- Discuss your target eye pressure and what realistic outcomes look like for your type of glaucoma
- Clarify how long you will need to stay in Thailand based on the procedure type
Travel & Logistics
Plan your trip with the extended stay and post-operative requirements in mind
- Book accommodation close to your hospital — frequent check-up visits are required, especially after trabeculectomy or tube shunt surgery
- Arrange transport to and from the hospital — you will not be able to drive after surgery
- If having trabeculectomy or tube shunt surgery, plan to stay in Thailand for at least 2-4 weeks
- Consider travel medical insurance that covers planned surgical procedures abroad — see our insurance guide for options suited to eye surgery
- Check visa requirements for your stay duration, especially if planning an extended recovery

Risks & Considerations
As with any medical procedure, there are potential risks to consider. Your medical team will discuss these with you in detail.
- Temporary IOP spike (5-10%, usually resolves within hours to days)
- Hyphema/blood in eye (5-20% for MIGS, usually self-resolving)
- Hypotony/low eye pressure (10-20% trabeculectomy, often temporary)
Additional considerations will be discussed during your consultation.

Frequently Asked Questions
Can glaucoma surgery restore lost vision?
No. Glaucoma surgery prevents further optic nerve damage but cannot restore vision already lost. This is why early detection and treatment are crucial. The goal of surgery is to lower eye pressure enough to halt disease progression and preserve your remaining vision.
Will I still need eye drops after surgery?
Many patients can reduce or eliminate drops, but some still need medications. MIGS procedures typically reduce drop requirements by 1-2 medications. Trabeculectomy often eliminates drops entirely, while tube shunts may reduce but not eliminate them. Your surgeon will monitor your pressure and adjust medications as needed.
Is MIGS better than trabeculectomy?
MIGS is safer with faster recovery but achieves less IOP reduction (20-35% vs 40-60%). Trabeculectomy is more powerful for advanced disease requiring aggressive pressure control. The best choice depends on your glaucoma severity, target IOP, and overall eye health. Many patients start with MIGS and progress to traditional surgery only if needed.
How long do surgery effects last?
Variable by procedure type. SLT laser may need repeating in 2-5 years. MIGS devices can last many years but may lose effectiveness over time. Trabeculectomy success rates are 70-90% at 5 years, declining to 50-70% at 10 years. Tube shunts maintain 70-80% success at 10 years. All require ongoing monitoring.
What is a bleb and how do I care for it?
A bleb is a fluid-filled blister under the conjunctiva (clear membrane over the white of your eye) created by trabeculectomy. It's how fluid drains from the eye to lower pressure. Blebs require lifelong monitoring for leaks and infection. Protect your eye from trauma, avoid rubbing, and report any redness, pain, or discharge immediately.
Can I have glaucoma surgery if I've had cataract surgery?
Yes. Many glaucoma surgeries can be performed after cataract surgery. Some MIGS devices are specifically designed for combination with cataract surgery. Previous eye surgery may affect which glaucoma procedure is most appropriate, so your surgeon will evaluate your specific situation.
Important: This information is for educational purposes only and does not constitute medical advice. Glaucoma surgery candidacy depends on the type and severity of glaucoma, target IOP, previous treatments, and overall eye health. You must consult with a qualified ophthalmologist who can examine your eyes and review your complete medical history before making any decisions about glaucoma surgery. Results vary by individual, and surgery cannot restore vision already lost to glaucoma.
Pricing Note: Costs shown are estimates based on hospital published rates and may vary based on procedure complexity, device selection, anesthesia requirements, and individual patient factors. Request a detailed quote from your chosen hospital.
Glaucoma is often called “the silent thief of sight” because it damages the optic nerve gradually, usually without noticeable symptoms until significant vision loss has occurred. Affecting over 80 million people worldwide, glaucoma is a leading cause of irreversible blindness. While eye drops and laser treatments are first-line therapies, surgery becomes necessary when these fail to adequately control intraocular pressure (IOP).
Critical understanding: Glaucoma surgery prevents further vision loss but cannot restore vision already damaged. Early detection and treatment are essential for preserving sight.
Types of Glaucoma Surgery
Laser Procedures
Laser treatments are often the least invasive option and can be performed in an office setting:
- SLT (Selective Laser Trabeculoplasty): Non-thermal laser to drainage tissue, 70-80% success rate at 1 year, can be repeated
- YAG Peripheral Iridotomy: Creates opening in iris for angle-closure glaucoma
- Cyclophotocoagulation: Reduces fluid production for refractory cases
MIGS (Minimally Invasive Glaucoma Surgery)
MIGS devices offer a safer profile than traditional surgery with faster recovery, often combined with cataract surgery:
| Device Type | IOP Reduction | Best Candidates |
|---|---|---|
| Trabecular bypass (iStent, Hydrus) | 20-35% | Mild-moderate glaucoma |
| Subconjunctival (XEN, PreserFlo) | 35-50% | Moderate glaucoma |
| Trabecular excision (Kahook) | 25-35% | Combined with cataract surgery |
Traditional Surgeries
For advanced glaucoma requiring aggressive IOP reduction:
- Trabeculectomy: Creates drainage bleb, 40-60% IOP reduction, 70-90% success at 5 years
- Tube Shunts (Ahmed, Baerveldt): Implanted drainage device, preferred for failed trabeculectomy or high-risk eyes
Success Rates
| Procedure | 1-Year Success | 5-Year Success | Typical IOP Reduction |
|---|---|---|---|
| SLT Laser | 70-80% | Variable (repeatable) | 20-30% |
| MIGS (trabecular) | 75-85% | Data emerging | 20-35% |
| Trabeculectomy | 85-90% | 70-80% | 40-60% |
| Tube Shunt | 90-95% | 80-85% | 40-60% |
International Patient Considerations
Glaucoma surgery for medical tourism patients requires careful planning because glaucoma is a chronic, lifelong condition:
Critical Planning Requirements
- Pre-surgery coordination: Identify a glaucoma specialist or ophthalmologist in your home country who will provide long-term monitoring BEFORE traveling for surgery
- Extended stay required: Trabeculectomy and tube shunt patients should plan 2-4 weeks minimum in Thailand for intensive early follow-up
- Bring complete records: Visual fields, OCT scans, IOP history, and medication records are essential for surgical planning
- Understand limitations: One surgery may not be sufficient—some patients require additional procedures
Follow-Up Requirements by Procedure
| Procedure | Thailand Stay | Follow-up Frequency | Long-term Monitoring |
|---|---|---|---|
| SLT Laser | 3-5 days | 1-3 months | Every 6-12 months |
| MIGS | 5-7 days | Day 1, Week 1, Month 1 | Every 3-6 months |
| Trabeculectomy | 2-4 weeks | Multiple times weekly initially | Every 3-6 months (lifelong bleb care) |
| Tube Shunt | 2-4 weeks | Multiple times weekly initially | Every 3-6 months |
Flying After Surgery
- SLT Laser: Same day
- MIGS: 3-5 days
- Trabeculectomy/Tube: 2-4 weeks (varies by healing)
- Important: If a gas bubble is used in surgery, flying is absolutely prohibited until the bubble resolves
