Flapless laser vision correction through an incision smaller than a grain of rice.
SMILE corrects short-sightedness without creating a corneal flap. A femtosecond laser shapes a thin disc of tissue inside the cornea, and the surgeon removes it through a 2–4mm keyhole incision. No excimer laser, no flap, and a cornea that retains more of its structural strength. Thailand adopted the technology early and now has some of the highest-volume SMILE surgeons in Southeast Asia.
Free, no-obligation — you pay the hospital directly with no markup.
ReLEx SMILE uses a single femtosecond laser to create a thin disc of corneal tissue — called a lenticule — inside the intact cornea. The surgeon removes this lenticule through a small peripheral incision, changing the corneal curvature and correcting the refractive error. No flap is created and no excimer laser is needed.
The practical advantage is corneal biomechanics. Because SMILE preserves the anterior stromal lamellae, the cornea retains significantly more structural strength than after LASIK. It also severs fewer corneal nerves, which means less post-operative dry eye. For patients who play contact sports or work in dusty or physically demanding environments, the absence of a flap removes an ongoing vulnerability.
Thailand was among the first countries in Southeast Asia to adopt the VisuMax platform, and its SMILE surgeons now rank among the most experienced in the region. Combined with significantly lower costs, it is a strong option for international patients.
Early Adopters
Established SMILE Expertise
Thai refractive centres adopted SMILE technology early and have built substantial case volumes. That matters for a technique where surgical handling directly affects outcomes.
40–60%
Significant Cost Savings
SMILE in Thailand costs a fraction of UK, US, or Australian prices. The technology is identical — the price difference reflects lower local operating costs, not lower standards.
Days, Not Months
Fast Scheduling
Assessment to surgery in days rather than the months-long wait typical of specialist clinics elsewhere. Ideal for patients with limited time off work or travel flexibility.
International
Coordinated Patient Care
English-speaking teams, airport transfers, hotel recommendations, and follow-up scheduling handled by a dedicated coordinator throughout your stay.
We do not charge for our service — you pay the hospital directly with no markup. Here is what SMILE typically costs, what affects the price, and how Thailand compares internationally.
Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
SMILE in Thailand typically costs between $1,800 and $3,200 for both eyes. The standard VisuMax procedure sits at the lower end, while SMILE Pro on the VISUMAX 800 commands a premium due to faster treatment times and robotic centration. Quotes should clearly state whether both eyes are included.
The total cost includes the surgeon's fee, femtosecond laser usage fee, facility charges, and post-operative care including medications and follow-up visits. The laser platform fee is a significant component because the disposable interfaces used for each patient are expensive. Unlike LASIK, there is no separate excimer laser charge because SMILE uses only one laser.
The primary variables are the laser platform generation and the surgeon's experience level. SMILE Pro costs more than standard SMILE because the newer platform is more expensive to operate. More experienced surgeons with higher case volumes may also charge more, and that premium is generally worth paying for a procedure where manual tissue handling directly affects the result.
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:

SMILE in Thailand costs 40–60% less than equivalent procedures in the US ($4,500–$7,200), Australia (A$4,100–A$6,800), and UK (£3,600–£6,300). The technology is identical — both standard and Pro platforms are available. The cost difference reflects lower operating expenses in Thailand, not lower clinical standards.
SMILE has evolved since its introduction, with newer platforms significantly reducing treatment time and improving centration accuracy. Your surgeon selects the approach based on your prescription and corneal measurements.
The original platform uses the Carl Zeiss VisuMax femtosecond laser. Lenticule creation takes approximately 25–30 seconds per eye. Proven track record with over six million eyes treated globally. Remains the workhorse for most SMILE procedures performed today.
The next-generation platform cuts lenticule creation to roughly 10 seconds per eye. Robotic centration and docking improve alignment accuracy and reduce the time spent under suction. Faster suction means greater comfort and less anxiety during the procedure.
SMILE is a single-technique procedure — there is no excimer laser step to vary. The main technical variables are the platform generation, lenticule design parameters, and whether a combined approach such as SMILE with cross-linking is appropriate for your case.
The surgeon programs lenticule diameter, thickness profile, and transition zone based on your prescription, pupil size, and corneal thickness. Getting these parameters right determines both the optical quality of the result and the residual corneal strength. Larger optical zones reduce night-time visual disturbances.
For patients with borderline corneal biomechanics or keratoconus suspects, cross-linking can be performed immediately after SMILE to strengthen the residual cornea. Riboflavin is applied to the stromal bed through the lenticule pocket, followed by UV-A exposure. This extends SMILE candidacy to some patients who would otherwise be excluded.
Mild blurring and watery eyes in the first few hours as the small incision begins to settle. A slight foreign body sensation usually resolves by evening. Vision is functional but not yet crisp. Rest your eyes as much as possible.
Vision clears noticeably. Most patients can read and use screens comfortably. A follow-up appointment confirms the incision site looks good and measures early visual progress. Continue lubricating drops as directed.
Acuity continues to improve as the cornea remodels around the extracted lenticule space. Light exercise can resume. Avoid swimming and eye make-up. Night vision sharpens progressively.
The cornea reaches its stable new curvature. Any lingering dryness resolves. A follow-up verifies that your prescription has settled and the corneal surface is fully intact.
Most patients can fly home 3–5 days after SMILE. There is no flap to worry about, and the small incision heals quickly. Dry cabin air can aggravate temporary post-SMILE dryness, so bring preservative-free lubricating drops and use them liberally during the flight. Your surgeon confirms travel readiness at your follow-up.
Desk work and screen use can resume within 2–3 days. Light exercise is fine after about a week. Contact sports can resume sooner than after LASIK because there is no flap to displace — typically 2–3 weeks. Swimming should wait until the incision has fully sealed, usually by week 3–4.
Functional vision returns within 2–3 days, and most patients are glasses-free by the end of the first week. Acuity continues to sharpen over the following 1–3 months as the corneal tissue remodels around the extracted lenticule space. The tip is slower recovery than LASIK in the first few days, but equivalent outcomes by 3 months.
SMILE has been performed on over six million eyes globally and carries a well-characterised safety profile. The flapless design eliminates an entire category of LASIK-related complications, but it introduces its own set of considerations.
The main risk-reduction factor is surgeon skill during lenticule extraction — this is a manual step that requires precise tissue handling. Volume and experience matter here more than for LASIK, where the laser does most of the work. Our partner surgeons have completed thousands of SMILE procedures.
Yes. Thailand's leading SMILE centres hold JCI accreditation and use Carl Zeiss VisuMax and VISUMAX 800 platforms — the only lasers approved for SMILE worldwide. Our partner surgeons are board-certified ophthalmologists with specific refractive surgery subspecialisation and high SMILE case volumes. The safety profile at these centres matches published international data.
Candidacy screening is the first line of defence. SMILE is currently approved only for myopia and myopic astigmatism, and there are strict corneal thickness and prescription limits. Surgeon experience with lenticule extraction is critical — this is where most complications arise, and it is entirely technique-dependent. Choose a surgeon who performs SMILE regularly, not occasionally.
If a residual prescription remains after SMILE, enhancement options include surface-based PRK on the corneal surface or, in some cases, thin-flap LASIK. SMILE enhancement by re-entering the lenticule pocket is technically possible but not yet widely practised. The need for enhancement after SMILE occurs in fewer than 5% of patients.
SMILE requires specific surgical skill during lenticule extraction that is more operator-dependent than LASIK. Choosing the right surgeon matters more here than for any other refractive procedure.
Our partner centres were among the first in Thailand to offer SMILE and now operate both VisuMax and VISUMAX 800 platforms. These are dedicated refractive surgery departments within JCI-accredited hospitals, staffed by ophthalmologists whose primary caseload is laser vision correction. They are not general eye clinics offering SMILE as a side service.
Our partner surgeons have completed thousands of SMILE procedures individually. That volume matters because the manual lenticule extraction step requires a feel for tissue planes that only comes with repetition. Several trained at international centres before returning to Thailand where refractive surgery volumes are among the highest in the region.
Ask specifically about SMILE case volume — not total refractive surgery volume, but SMILE specifically. The lenticule extraction step is the key differentiator, and a surgeon who performs it daily handles it very differently from one who does it monthly. Ask about enhancement rates and complication rates. A surgeon who is transparent about their numbers is usually the one worth trusting.
SMILE delivers equivalent visual outcomes to LASIK by 3 months, with the added advantage of greater corneal structural preservation.
Over 95% of SMILE patients achieve 20/20 vision or better within 3 months. Visual recovery is slightly slower than LASIK in the first few days — most patients notice good functional vision by day 2–3 rather than day 1 — but outcomes converge by the one-month mark. The correction is permanent, and the flapless design means the cornea is structurally stronger long-term.
Your pre-operative assessment determines the predicted outcome based on prescription, corneal thickness, and lenticule design parameters. Patients within the approved treatment range (-1.00 to -10.00 dioptres of myopia, up to -5.00 dioptres of astigmatism) can expect outcomes comparable to those published in major clinical trials. Your surgeon will discuss both the likely result and the small probability of needing an enhancement.
SMILE requires the same short stay as LASIK — most patients need 3–5 days in Thailand from assessment to travel clearance.
Plan for 3–5 days. Day 1 covers your comprehensive assessment including corneal topography, pachymetry, and wavefront aberrometry. Surgery can often be scheduled for day 2. Follow-up on day 3 confirms healing, and most patients are cleared to fly by day 4 or 5. Add a couple of days if you want a more relaxed schedule.
Your care coordinator manages scheduling, hospital transfers, and follow-up logistics. The surgical quote covers the pre-operative assessment, femtosecond laser procedure for both eyes, surgeon and facility fees, post-operative medications and drops, and follow-up appointments. Flights and accommodation are arranged separately, with hotel recommendations provided.
SMILE recovery is straightforward and Bangkok is the ideal base. You are close to the hospital for follow-ups, and within 48 hours most patients feel comfortable enough to explore the city. There are no positioning requirements or physical restrictions beyond avoiding eye rubbing and swimming for the first few weeks.
