Targeted medication delivered directly inside the eye, where it stops sight-threatening leakage at its source.
When abnormal blood vessels grow or leak inside the eye, anti-VEGF injections stop the damage at its molecular source. A fine needle delivers medication directly into the vitreous cavity, blocking the protein that drives vessel growth and leakage. These treatments have transformed outcomes for wet macular degeneration, diabetic macular oedema, and retinal vein occlusions — conditions that used to lead to irreversible blindness.
Free, no-obligation — you pay the hospital directly with no markup.
Intravitreal injection delivers anti-VEGF medication directly into the vitreous cavity using a very fine needle. The most common agents are ranibizumab (Lucentis), aflibercept (Eylea), and bevacizumab (Avastin) — each blocking the vascular endothelial growth factor that drives abnormal vessel proliferation and leakage.
Treatment usually begins with a loading phase of three monthly injections, then transitions to a treat-and-extend protocol guided by OCT imaging. The intervals between injections are gradually lengthened as long as the retina stays dry. Some patients achieve long-term stability, while others require ongoing maintenance. Thailand's retinal centres offer all approved agents and follow the same evidence-based protocols used internationally.
Intravitreal injections are performed identically worldwide. The main reason international patients come to Thailand is cost — particularly for patients who need ongoing treatment and are paying out of pocket.

Intravitreal injections in Thailand typically cost between $800 and $1,450 per injection, depending on the agent used. Bevacizumab is the most affordable option. Ranibizumab and aflibercept cost more but are purpose-designed for intravitreal use with the strongest regulatory approval. The price includes the consultation, OCT assessment, injection, and immediate post-injection monitoring.
Each session includes the retinal specialist consultation, OCT imaging assessment, the anti-VEGF medication itself, sterile injection procedure, facility fee, and immediate post-injection pressure check. For patients on ongoing treatment, package pricing for multiple injections during a single trip may be available.
The anti-VEGF agent is the main cost variable. Bevacizumab costs significantly less per injection than ranibizumab or aflibercept. For patients needing 6–12 injections per year, the choice of agent has a major impact on annual treatment cost. Clinical efficacy data supports all three agents for most indications.
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:
Exact pricing is confirmed after your consultation and treatment plan are finalised.
Intravitreal injections in Thailand cost 40–60% less per injection than in the US ($2,000–$3,200), Australia (A$1,850–A$3,050), and UK (£1,600–£2,800). Over a year of treatment involving 6–8 injections, the savings can amount to thousands of dollars.
All three major anti-VEGF agents are available. The choice between them depends on clinical evidence for your specific condition, cost considerations, and in some cases individual treatment response. Your retinal specialist will recommend the most appropriate option.
Purpose-designed anti-VEGF agents with robust clinical trial data for wet AMD, diabetic macular oedema, and retinal vein occlusion. Both are approved specifically for intravitreal use. Aflibercept binds VEGF more tightly and may allow longer treatment intervals for some patients.
An anti-VEGF antibody used off-label for intravitreal injection at significantly lower cost. Large comparative trials (CATT, IVAN) demonstrated similar efficacy to ranibizumab for wet AMD. Widely used globally — particularly valuable when multiple injections make cost a practical concern.
The injection technique itself is standardised globally. What differs between centres is the quality of the sterile protocol, the diagnostic imaging used to guide treatment, and the clinical judgment applied to treatment scheduling.
Optical coherence tomography provides high-resolution cross-sectional images of the retina at each visit. Fluid levels, retinal thickness, and subretinal fluid presence are measured to determine whether the current injection interval should be maintained, shortened, or extended. This data-driven approach minimises unnecessary injections while maintaining disease control.
Povidone-iodine antisepsis, sterile draping, single-use needles, and lid speculum are standard. The injection site is 3.5–4.0mm from the limbus, directed toward the centre of the eye. The entire process takes seconds. Rigorous sterile technique is what keeps the extremely rare risk of endophthalmitis at its lowest possible level.
Your eye may feel slightly gritty or watery. Small floaters or air bubbles in your vision are common and settle within hours. The topical anaesthetic wears off within an hour. Avoid rubbing your eye.
Most patients experience no significant discomfort. All normal activities including reading and screen use can resume. A small red spot on the white of the eye may be visible — this is harmless subconjunctival haemorrhage that resolves within a week.
Any minor irritation or redness resolves. Vision may begin to show improvement as retinal fluid starts to clear, though the full effect develops over days to weeks.
OCT assessment evaluates treatment response. Based on retinal fluid levels and thickness, the next injection is scheduled accordingly. During a loading phase, injections are typically every 4 weeks.
There are no flying restrictions after intravitreal injections. You can fly the same day or the next day. The procedure does not involve gas tamponade or incisions that are affected by cabin pressure. A brief follow-up before departure confirms the eye is stable.
Virtually none. Normal activities including reading, screen use, exercise, and daily routines can resume immediately. Avoid rubbing the eye for a day or two. Swimming can resume after 24–48 hours. This is one of the least disruptive medical procedures in ophthalmology.
Each injection provides temporary disease control — typically 4–8 weeks depending on the agent and your treatment response. Anti-VEGF therapy manages the disease rather than curing it. With consistent treatment and OCT-guided scheduling, most patients maintain stable vision long-term. Some patients eventually achieve treatment-free stability, while others require ongoing maintenance.
Intravitreal injections are very safe when performed under rigorous sterile conditions. The risk of serious complications is low, and the benefit for sight-threatening conditions far outweighs the risks in virtually all cases.
The most feared complication — endophthalmitis — is extremely rare at centres that follow rigorous sterile protocols. Povidone-iodine antisepsis, single-use instruments, and sterile draping are non-negotiable standards. Our partner centres maintain infection rates well below published international benchmarks.
Yes. The injection technique and sterile protocol are identical worldwide. Thailand's retinal centres follow rigorous infection-control standards including povidone-iodine antisepsis, sterile draping, and single-use instruments. Our partner ophthalmologists are fellowship-trained retinal specialists who perform high volumes of injection therapy. Infection rates at accredited centres are consistent with international benchmarks.
Anti-VEGF agents have been used intravitreally for nearly two decades, with extensive long-term safety data. The main concerns — endophthalmitis and sustained pressure elevation — are rare and well managed with proper technique and monitoring. The benefit for sight-threatening conditions consistently outweighs the small procedural risk.
Delaying or skipping injections allows the underlying disease to become active again. Fluid reaccumulates, blood vessels leak, and further vision loss can occur. Adherence to the recommended treatment schedule is important — if you cannot travel to Thailand for every injection, arrange continuation with a retinal specialist at home. Consistent treatment produces the best long-term results.
Intravitreal injections are performed by retinal specialists, not general ophthalmologists. The injection itself is straightforward, but the treatment decisions — which agent, what interval, when to extend — require subspecialist judgment.
Our partner centres have dedicated retinal departments with OCT suites, fluorescein angiography, widefield imaging, and injection rooms with full sterile protocols. All three anti-VEGF agents are stocked and available for immediate use. These are active retinal treatment centres with high patient volumes.
Our partner retinal specialists manage large cohorts of anti-VEGF patients and follow evidence-based treat-and-extend protocols. They adjust treatment intervals based on OCT data, not calendar schedules, which reduces the total injection burden while maintaining disease control.
For patients who start treatment in Thailand and continue at home, our team prepares a comprehensive treatment report including OCT images, injection history, and recommended treatment interval. This allows straightforward handover to your local retinal specialist. For patients who prefer to return to Thailand for treatment, visits can be coordinated to include multiple injections during a single trip.
Anti-VEGF therapy has transformed the outcomes for conditions that used to cause irreversible blindness.
In wet AMD, anti-VEGF therapy prevents further vision loss in over 90% of patients and improves vision in 30–40%. In diabetic macular oedema, most patients achieve stable or improved central vision with consistent treatment. In retinal vein occlusion, anti-VEGF significantly reduces macular oedema and improves acuity. These are landmark results backed by decades of clinical trial data.
Treatment response varies by condition, severity at presentation, and treatment adherence. Patients treated early — before significant structural damage occurs — have the best outcomes. Your retinal specialist will discuss expected outcomes based on your OCT findings and diagnosis. Consistent adherence to the injection schedule is the single most important factor in long-term visual preservation.
Intravitreal injections require the shortest stay of almost any ophthalmic procedure. A single injection visit needs just 3–5 days. A loading course of three can be planned over multiple visits or a longer single stay.
For a single injection, 3–5 days covers the consultation, OCT assessment, injection, and follow-up. If you are starting a loading course (three monthly injections), you can schedule the first during your Thailand trip and continue the remaining two at home, or plan a longer stay to complete the series.
Each injection session includes retinal specialist consultation, OCT imaging assessment, the anti-VEGF injection, sterile procedure room, post-injection monitoring, and care coordination. Your coordinator can build a schedule that includes multiple injections during a single extended trip if preferred.
Most patients need ongoing injections for months to years. Starting in Thailand and continuing with a retinal specialist at home is a common and practical approach. Your Thai retinal surgeon provides a detailed report and treatment plan for coordinated handover. Some patients return to Thailand periodically for injection batches to benefit from lower per-injection costs.
