When laser surgery cannot reach your prescription, the ICL picks up where it leaves off.
The ICL is the go-to procedure for patients with prescriptions too high for laser surgery. A biocompatible lens is placed behind the iris and in front of the natural lens, correcting severe myopia and astigmatism without removing any corneal tissue. It is reversible, it delivers optical quality that lasers cannot match at high dioptres, and Thailand has some of the highest-volume ICL surgeons in the region.
Free, no-obligation — you pay the hospital directly with no markup.
The ICL is a biocompatible phakic intraocular lens inserted through a 2.8mm micro-incision and positioned in the sulcus between the iris and the natural lens. It works with your existing lens to focus light on the retina, correcting myopia from -0.50 to -18.00 dioptres and astigmatism up to 6.00 dioptres.
The current-generation EVO+ design includes a central port that allows natural aqueous flow, eliminating the need for a pre-operative iridotomy. The lens is made of Collamer — a biocompatible collagen co-polymer that does not cause inflammation and blocks harmful UV light. Because no corneal tissue is removed, the procedure is fully reversible.
ICL implantation requires meticulous sizing and surgical precision. Thailand's specialist eye centres have been performing this procedure for years and offer both the expertise and the cost advantage that attract patients from across the region.
High Volume
Experienced ICL Surgeons
Our partner surgeons are among the highest-volume ICL implanters in Southeast Asia. That volume directly translates to better sizing accuracy and fewer complications.
40–60%
Substantial Savings
The ICL lens itself is expensive globally, but surgeon fees and facility costs in Thailand are significantly lower. The total package is 40–60% less than the US, UK, or Australia.
1–2 Weeks
Assessment to Surgery
Lens ordering adds time, but the clinical pathway from first consultation to surgery is measured in days rather than the months typical of specialist centres elsewhere.

Coordinated Care
From biometric measurements through surgery to vault verification, your care coordinator manages every step. Communication with your team is direct and in English.
We do not charge for our service — you pay the hospital directly with no markup. ICL is more expensive than laser procedures because the lens itself has a significant cost, but Thailand still offers substantial savings.
Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
ICL surgery in Thailand typically costs between $3,500 and $6,300 for both eyes. The EVO+ Visian ICL lenses account for a large portion of the total cost — they are manufactured exclusively by STAAR Surgical and priced globally. Surgeon fees and facility charges make up the remainder, and this is where Thailand's cost advantage is most apparent.
The total includes the ICL lenses (one per eye), pre-operative biometric assessment using anterior segment OCT and ultrasound biomicroscopy, surgeon fees, anaesthesia, facility charges, post-operative medications, and follow-up visits during your stay. Toric lenses for astigmatism correction may carry a small additional charge.
The biggest variable is the lens type. Toric ICLs cost more than spherical models because they include astigmatism correction. Higher-powered lenses at the extreme ends of the dioptre range may also carry a premium. Surgeon experience and hospital accreditation level affect facility fees. The biometric assessment is included regardless of the lens chosen.
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.
ICL in Thailand costs 40–60% less than equivalent procedures in the US ($8,800–$14,000), Australia (A$8,000–A$13,300), and UK (£7,000–£12,300). The lens cost is similar globally, so the savings are primarily on surgical and facility fees. Our partner hospitals are JCI-accredited and use the same EVO+ lenses available worldwide.
The ICL is a single-product family from STAAR Surgical, but the choice between spherical and toric models — and getting the sizing right — is what determines the quality of the result.
Corrects myopia only. The central CentraFLOW port maintains aqueous circulation without needing a laser iridotomy beforehand. Available in four sizes to match different sulcus-to-sulcus diameters. Appropriate for patients whose astigmatism is negligible or below 0.75 dioptres.
Corrects both myopia and astigmatism simultaneously. The toric axis is marked on the cornea before surgery and the lens rotated to the correct orientation during implantation. Eliminates the need for a separate astigmatism correction step.
ICL implantation is a brief but precision-critical intraocular procedure. The accuracy of pre-operative sizing determines long-term safety, and the surgical technique determines day-one outcomes.
Accurate ICL sizing requires measuring the sulcus-to-sulcus diameter — the internal distance between the structures where the lens rests. Anterior segment OCT and ultrasound biomicroscopy provide this measurement. Incorrect sizing is the main preventable risk factor for ICL complications, which is why this step matters more than the surgery itself.
The ICL is injected through a 2.8mm self-sealing corneal incision using a proprietary cartridge system. Once inside the eye, the lens unfolds and the surgeon positions it behind the iris using specialised manipulators. The incision is typically sutureless and heals within days.
Vision improves dramatically within hours. Mild light sensitivity and a slight awareness of the micro-incision are normal. A post-operative exam confirms ICL position and vault. You receive a protective eye shield for sleeping.
Vision sharpens further as the micro-incision heals and any mild corneal oedema resolves. Intraocular pressure and vault are rechecked at follow-up. Most patients can resume reading, screen work, and light daily activities.
The eye feels comfortable and vision stabilises. Anti-inflammatory and antibiotic drops continue as prescribed. You can resume exercise but should avoid swimming, heavy lifting, and rubbing the eyes.
Vault, pressure, and refractive stability are confirmed at a comprehensive review. The ICL has settled into its permanent position and the micro-incision has healed completely. All activities, including swimming, can resume.
Most patients can fly home 5–7 days after ICL implantation, once the surgeon has confirmed stable vault and pressure at follow-up. Flying does not affect the implanted lens. Mild dryness from cabin air is manageable with lubricating drops. If both eyes are treated on separate days, plan your departure from the second procedure's follow-up date.
Desk work and screen use can resume within 2–3 days. Light exercise is fine after a week. Swimming should wait until the micro-incision has fully healed, usually 2–3 weeks. Heavy lifting and strenuous exertion should be avoided for the first week to keep intraocular pressure stable.
Visual improvement is dramatic and almost immediate — most patients notice a significant change within hours. The refraction stabilises within the first few days, and by the 1-month follow-up the result is essentially final. Unlike laser procedures, there is no gradual remodelling phase. What you see in the first week is very close to what you keep.
ICL implantation is an intraocular procedure with over two million lenses implanted worldwide. The safety profile is strong, but placing a device inside the eye carries specific risks that differ from laser surgery.
The overwhelming majority of ICL complications trace back to sizing errors — either the lens is too large (high vault, risking pigment dispersion and pressure spikes) or too small (low vault, risking lens touch and cataract). Choosing a surgeon who performs high volumes of ICL procedures and uses multiple biometric modalities for sizing is the single most important risk-reduction step.
Yes. Thailand's specialist eye centres hold JCI accreditation and use the same EVO+ Visian ICL lenses as every other accredited centre worldwide. Our partner surgeons are board-certified with specific anterior segment and refractive surgery training. Several hold international fellowships and have completed hundreds of ICL implantations individually.
Sizing accuracy is everything. Ensure your centre uses both anterior segment OCT and ultrasound biomicroscopy to measure the sulcus — relying on a single modality increases the risk of sizing error. Ask your surgeon what vault range they target and what their lens exchange rate is. A low exchange rate indicates good sizing accuracy. Post-operatively, attend all scheduled vault and pressure checks during your stay.
If the vault is too high or too low at early follow-up, the ICL can be exchanged for a different size. This is a straightforward procedure when performed promptly. The key is detecting the issue early — which is why post-operative vault checks on days 1–3 are part of the standard protocol. Our partner centres monitor this closely before clearing you to travel.
ICL surgery is more technically demanding than LASIK and requires specific expertise in intraocular lens implantation and anterior segment biometry. Here is what sets our partner centres apart.
Our partner hospitals have dedicated refractive surgery and anterior segment departments with the full suite of biometric imaging — Scheimpflug, anterior segment OCT, and ultrasound biomicroscopy. They stock the full range of EVO+ ICL sizes and powers, reducing the wait time between assessment and surgery. These are not clinics that order lenses case by case.
Our partner surgeons have individually implanted hundreds to thousands of ICLs. That volume matters because sizing judgment improves with experience — the relationship between measured dimensions and optimal vault is not purely mathematical. Surgeons with high case volumes develop an intuition for borderline sizing decisions that newer implanters lack.
Ask about their total ICL case volume and their lens exchange rate. A surgeon who exchanges fewer than 2% of implanted lenses has good sizing accuracy. Check that they use multiple biometric modalities for sizing rather than relying on a single measurement. And ask whether they perform early vault checks on day 1 — surgeons who do this catch problems before they become complications.
ICL results are among the most dramatic in ophthalmology because the patients start from such high prescriptions.
Patients routinely go from -8.00 or -12.00 dioptres of myopia to seeing clearly without any correction. Visual acuity outcomes consistently match or exceed what is achievable with glasses or contacts at high prescriptions. The ICL actually delivers better optical quality than spectacles for very high myopia because it eliminates the minification and distortion inherent in thick minus lenses.
The pre-operative biometric assessment predicts the expected outcome based on your prescription, anterior chamber dimensions, and lens power calculation. Most patients achieve better than 20/25 uncorrected acuity, and many reach 20/20. The improvement in quality of vision — not just acuity but contrast, peripheral clarity, and image size — is something that spectacle wearers with high myopia notice immediately.
ICL requires a longer stay than laser procedures because both eyes are typically treated on separate days. Plan for 5–7 days minimum.
Plan for 5–7 days. Day 1 is your comprehensive biometric assessment. Surgery for the first eye is typically scheduled within 1–2 days, with the second eye treated 1–3 days later. Follow-up appointments after each eye check vault and pressure. Most patients are cleared to fly once both eyes have been assessed and are stable.
Your care coordinator handles scheduling, hospital transfers, and all follow-up logistics. The surgical quote covers biometric assessment, EVO+ ICL lenses for both eyes, surgeon and facility fees, post-operative medications, and follow-up appointments. Flights and accommodation are arranged separately, with hotel recommendations near the hospital provided.
ICL recovery is one of the fastest in ophthalmology — most patients see dramatically better by the evening of surgery. Bangkok is ideal because you are close to the hospital for the vault checks that happen over the first few days. Between appointments, you can explore the city comfortably. Just avoid swimming pools and dusty environments for the first couple of weeks.
