Selective Laser Trabeculoplasty in Thailand: Cost, Top Specialists & Hospitals

SLT delivers short pulses of low-energy light to pigmented cells in the trabecular meshwork, stimulating a biological remodelling response that improves aqueous outflow. It treats open-angle glaucoma and ocular hypertension with an average pressure reduction of 20–30%.

Unlike older argon laser trabeculoplasty, SLT causes no coagulative tissue damage — which is why it can be repeated. The landmark LiGHT trial demonstrated SLT is as effective as daily eye drops for initial glaucoma management. For many patients, it reduces or eliminates the need for topical medications.

SLT in Thailand typically costs between $800 and $1,450 per eye or per session. The total includes the glaucoma specialist consultation, gonioscopy examination, laser treatment, post-treatment pressure check, anti-inflammatory drops, and a follow-up appointment. Bilateral treatment in one session may be offered at a package rate.

The total covers the glaucoma specialist fee, SLT laser usage fee, topical anaesthesia, post-treatment pressure monitoring, a short course of anti-inflammatory drops, and a follow-up visit. The costs are predictable because the procedure is standardised.

Minimal variation. The main variables are whether one or both eyes are treated, and the hospital tier. 360-degree and 180-degree treatments are priced similarly. The treatment is standardised and the costs reflect the specialist fee and laser usage.

Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:

• SLT (one eye): $800–$950 — single-session laser targeting trabecular meshwork pigment cells
• SLT (both eyes, same session): $950–$1,200 — bilateral treatment performed back-to-back
• Repeat SLT (retreatment): $1,100–$1,450 — second round of laser for patients whose initial response has diminished

Exact pricing is confirmed after your consultation and treatment plan are finalised.

SLT in Thailand costs 40–60% less than in the US ($2,000–$3,200), Australia (A$1,850–A$3,050), and UK (£1,600–£2,800). The laser technology and treatment protocols are identical globally. If retreatment is needed years later, the cumulative savings from treating in Thailand are multiplied.

There are no flying restrictions after SLT. You can fly the same day if needed. Most patients stay 3–5 days for the consultation, treatment, and a follow-up pressure check before departure.

None. Normal activities resume immediately. There is no recovery period, no eye patching, and no physical limitations. SLT is among the least disruptive medical procedures available.

The full effect develops over 4–6 weeks. Your home glaucoma specialist will measure your pressure during this period to assess the response. If the pressure reduction is sufficient, drops may be reduced or stopped. If the reduction is insufficient, additional medical or surgical options are discussed.

Yes. SLT is a standardised laser procedure performed worldwide with identical equipment and protocols. Thailand's glaucoma centres use the same frequency-doubled Nd:YAG lasers as Western specialist centres. Our partner ophthalmologists are fellowship-trained glaucoma specialists with extensive SLT experience.

Yes. The LiGHT trial demonstrated that SLT is as effective as daily drops for initial glaucoma treatment and may even be superior in terms of disease control. Many patients achieve drop-free pressure control after SLT. Whether drops can be stopped depends on your target pressure and how well you respond to the laser.

Because SLT causes no structural damage to the trabecular meshwork, it can be repeated when the effect diminishes. Many patients undergo 2–3 treatments over the course of their glaucoma management. There is no fixed limit on retreatments, making SLT a sustainable long-term option.

Our partner centres have dedicated glaucoma departments with gonioscopy capability, visual field analysers, OCT for optic nerve assessment, and SLT laser systems. They offer the full range of glaucoma treatments — SLT, MIGS, trabeculectomy, and tube shunts — ensuring the recommendation you receive is based on what is best for your glaucoma, not what the centre can offer.

Our partner glaucoma specialists follow evidence-based SLT protocols. They can advise on whether SLT is appropriate as a first-line treatment, as an adjunct to drops, or as a step before considering surgical options. That contextual decision-making matters more than the laser procedure itself.

After SLT in Thailand, your treatment response needs monitoring over the following weeks at home. Our team prepares a treatment report for your home glaucoma specialist including the treatment parameters, immediate pressure response, and recommended follow-up schedule. This ensures well-managed continuity of care.

SLT achieves an average 20–30% reduction in intraocular pressure. The LiGHT trial showed that over 75% of patients treated with SLT as first-line therapy maintained target pressure for at least 3 years without needing drops. The effect typically lasts 3–5 years and can be repeated.

Response varies between patients. Some achieve excellent pressure reduction from a single session. Others see a more modest response and may need drops to supplement the effect. Your glaucoma specialist will assess the response at follow-up and adjust the management plan accordingly. SLT does not damage the optic nerve or visual field — it simply lowers pressure.

3–5 days. Assessment, gonioscopy, and SLT can often be completed on the same day or within 24 hours. A follow-up pressure check the next day or 2 days later confirms the early response. You are then free to fly home.

Your care coordinator schedules the consultation, treatment, and follow-up. The quote covers the specialist fee, laser treatment, post-treatment monitoring, drops, and follow-up visit. Flights and accommodation are separate.

If you need additional glaucoma assessment — visual field testing, OCT nerve analysis, medication review — these can all be completed during the same trip. For patients considering MIGS or surgical options, the consultation covers the full range of possibilities.
