SMILE Pro for High Myopia in Korea: Is It Suitable?
Introduction
If you have high myopia and are considering vision correction in South Korea, you may be wondering whether SMILE Pro can correct high myopia or whether another procedure, such as EVO ICL, may be more appropriate.
SMILE Pro is an advanced small-incision laser procedure designed to correct myopia and certain types of astigmatism. It does not create a conventional LASIK flap and can provide rapid visual recovery for suitable patients. However, having a high prescription does not automatically mean that SMILE Pro is the best choice.
For patients with high myopia, the decision depends on more than the number written on a glasses prescription. Corneal thickness, corneal shape, residual stromal tissue, retinal health, dry-eye status, prescription stability, and overall eye anatomy all need to be evaluated.
In Korea, patients can generally discuss several vision-correction options during a comprehensive examination, including SMILE Pro, LASIK, LASEK, and implantable contact lenses such as ICL. Busan Vision Clinic specifically notes that ICL may be considered for patients with high myopia, thin corneas, or prescriptions that may not be ideal for laser correction.
What Is SMILE Pro?
How SMILE Pro Works
SMILE Pro stands for Small Incision Lenticule Extraction Pro. It uses a femtosecond laser to create a precisely shaped lenticule inside the cornea.
The surgeon then removes the lenticule through a small incision. Removing this tissue changes the curvature of the cornea and helps light focus more accurately on the retina.
Unlike LASIK, SMILE Pro does not require the creation of a traditional corneal flap.
Busan Vision Clinic describes SMILE Pro as a minimally invasive procedure for suitable myopia and astigmatism cases, with comprehensive diagnostic testing used to determine whether it is appropriate for each patient.
Why SMILE Pro Is Attractive to Some Patients
The small-incision approach is one of the main differences between SMILE Pro and LASIK.
Potential advantages for suitable patients include:
- No conventional LASIK flap
- Small corneal incision
- Rapid laser treatment
- Potentially fast visual recovery
- Reduced dependence on glasses or contact lenses
- Different treatment option for suitable myopia and astigmatism
However, these advantages do not mean that SMILE Pro is automatically the safest procedure for someone with high myopia.
Can SMILE Pro Correct High Myopia?
The Answer Depends on How High the Prescription Is
The term “high myopia” can refer to different prescription levels depending on the clinical context.
SMILE technology has approved treatment ranges that vary by regulatory jurisdiction and specific device indication. For example, current U.S. FDA labeling for the VisuMax system includes an indication for SMILE for spherical refractive error from -1.00 D through -10.00 D, with specified cylinder and spherical-equivalent limits.
That does not mean every patient with a prescription near -10.00 D is automatically suitable.
A patient with -8.00 D may have excellent corneal measurements for laser surgery, while another patient with a lower prescription may have corneal characteristics that make laser treatment inappropriate.
Why Your Prescription Alone Is Not Enough
High myopia requires careful evaluation because laser vision correction removes corneal tissue.
The surgeon needs to determine whether the planned correction can be performed while maintaining adequate corneal structure.
This is why a comprehensive examination is essential before deciding between SMILE Pro, LASIK, LASEK, and ICL.
What Tests Are Needed for High Myopia?
Corneal Thickness Measurement
Corneal thickness is one of the most important measurements before laser eye surgery.
The surgeon needs to understand how much corneal tissue is available and how much will be affected by the planned treatment.
A thinner cornea may limit the suitability of certain laser procedures, particularly when a large refractive correction is required.
Corneal Topography and Tomography
Corneal mapping provides information about the shape and regularity of the cornea.
This is particularly important for high-myopia patients because identifying irregular corneal patterns can influence whether laser surgery is appropriate.
Busan Vision Clinic lists corneal topography and corneal thickness testing among the diagnostic evaluations used before vision-correction procedures.
Retinal Examination
High myopia can be associated with changes in the retina and other structures at the back of the eye.
Laser vision correction changes the cornea; it does not remove the underlying risks associated with high myopia.
For this reason, a comprehensive high-myopia assessment should include retinal evaluation rather than focusing only on the glasses prescription.
Tear-Film and Dry-Eye Evaluation
The ocular surface should also be assessed.
Patients with significant dry eye may require treatment before refractive surgery. Dry-eye symptoms can occur after laser vision correction, and pre-existing ocular-surface problems can influence recovery and visual quality.
Who May Be Suitable for SMILE Pro With High Myopia?
Stable High Myopia
A stable prescription is an important consideration.
If your prescription has changed significantly over the past year, your ophthalmologist may recommend waiting before elective refractive surgery.
The FDA labeling for the relevant SMILE indication requires documented refractive stability over the previous year.
Healthy Corneas
High-myopia patients considering SMILE Pro should have corneas with suitable thickness and shape.
A normal glasses prescription does not tell the surgeon whether the cornea can safely undergo the required tissue change.
Healthy Eyes Overall
The ophthalmologist may also evaluate:
- Retina
- Eye pressure
- Tear film
- Cornea
- Pupil size
- Lens health
- General eye health
A comprehensive assessment helps identify conditions that could make laser vision correction unsuitable.
When Might SMILE Pro Not Be the Best Choice for High Myopia?
Very High Prescriptions
When the refractive correction is particularly large, the amount of corneal tissue required for treatment becomes an important consideration.
Depending on the prescription and corneal anatomy, the surgeon may recommend an alternative procedure rather than attempting to correct the entire prescription with a corneal laser procedure.
The safest option is determined by examination findings—not by the desire to avoid glasses at any cost.
Thin Corneas
Thin corneas may reduce the suitability of laser procedures.
Busan Vision Clinic notes that patients with high myopia or thin corneas may be candidates for ICL when laser procedures are less suitable.
Irregular Corneal Shape
Certain corneal abnormalities can increase the risks associated with corneal laser surgery.
If topography or tomography reveals an irregular pattern, the ophthalmologist may recommend against SMILE Pro and consider another approach.
SMILE Pro vs ICL for High Myopia
How the Procedures Differ
SMILE Pro and ICL correct vision in very different ways.
SMILE Pro reshapes the cornea by removing a small amount of corneal tissue through a small incision.
ICL, or implantable contact lens surgery, places a biocompatible lens inside the eye without removing corneal tissue.
This distinction can be particularly relevant for patients with high myopia.
Why ICL May Be Considered for High Myopia
ICL may be considered when the prescription is outside a suitable laser-treatment range, when the cornea is too thin for the planned correction, or when preserving corneal tissue is an important consideration.
Busan Vision Clinic's information describes EVO ICL as an option for patients with moderate to high myopia, thin corneas, or conditions that may make LASIK, LASEK, or SMILE Pro less suitable.
The clinic's published information also lists high-myopia correction up to -18.00 D among potential ICL indications.
The exact lens range and candidacy requirements depend on the specific ICL system and the patient's eye anatomy.

Neither procedure is universally better. For high myopia, the comparison should be based on the patient's complete eye examination.
Is SMILE Pro Safer Than ICL for High Myopia?
Different Procedures Have Different Risks
It would be misleading to describe one procedure as universally safer.
SMILE Pro is a corneal laser procedure, while ICL is an intraocular procedure. They therefore have different benefits, limitations, and potential complications.
SMILE Pro avoids an implanted lens but requires removal of corneal tissue.
ICL preserves the corneal tissue but involves placing a lens inside the eye.
The appropriate choice should be based on your anatomy, prescription, eye health, and long-term visual goals.
Why Individual Assessment Matters
Two patients with the same prescription may receive different recommendations.
For example:
- Patient A may have a suitable corneal thickness and shape and be considered for SMILE Pro.
- Patient B may have a thin cornea and high myopia and be advised to consider ICL.
The prescription may be identical, but the anatomy is different.
Can SMILE Pro Correct -10.00 D Myopia?
Treatment Range Is Not the Same as Guaranteed Eligibility
The current U.S. FDA labeling for the VisuMax SMILE system includes spherical refractive errors up to -10.00 D under specified conditions.
However, a prescription at the upper end of an approved range should not be interpreted as a guarantee that treatment is appropriate.
The surgeon still needs to evaluate corneal thickness, shape, stability, astigmatism, ocular health, and other factors.
For patients with prescriptions beyond the appropriate SMILE range, ICL may be considered depending on the patient's anatomy and local treatment availability.
What Are the Benefits of SMILE Pro for Suitable High-Myopia Patients?
Small-Incision Approach
One of the defining features of SMILE Pro is its small incision.
Unlike LASIK, there is no conventional flap. This can be appealing to patients who want a flapless laser procedure.
Fast Treatment
The laser portion of SMILE Pro is very brief.
However, patients should remember that the total clinic visit includes preparation, diagnostic confirmation, surgery, and postoperative instructions.
Potentially Quick Visual Recovery
Many suitable patients experience noticeable improvement in vision soon after surgery.
However, visual stabilization continues during the healing period, and individual recovery varies.
Busan Vision Clinic reports that many patients experience significant visual improvement within the first few days after SMILE Pro.
What Are the Limitations of SMILE Pro for High Myopia?
Not Every High-Myopia Patient Is a Candidate
High myopia can make treatment planning more complex.
Some patients may have:
- Insufficient corneal thickness
- Irregular corneal shape
- Unstable prescription
- Significant dry eye
- Retinal concerns
- A prescription outside the suitable treatment range
In these situations, another procedure may be more appropriate.
Laser Surgery Does Not Eliminate High-Myopia Risks
This is an important point for patients.
Correcting the refractive error does not necessarily remove all structural risks associated with high myopia.
Even after successful vision correction, patients may still need appropriate eye examinations, particularly when they have a history of significant myopia.
What Is Recovery Like After SMILE Pro?
Early Recovery
Patients may experience improving vision shortly after treatment, but temporary symptoms can occur.
These may include:
- Mild dryness
- Light sensitivity
- Fluctuating vision
- Irritation
- Glare or other visual symptoms
The recovery timeline varies from patient to patient.
Follow-Up Is Important
Patients should attend the postoperative examinations recommended by their ophthalmologist.
International patients should plan enough time in Korea for appropriate follow-up rather than scheduling surgery immediately before leaving the country.
SMILE Pro for High Myopia in Korea: What Should International Patients Know?
Get a Complete Examination Before Booking Surgery
If you are traveling to Korea specifically for high-myopia treatment, avoid choosing SMILE Pro solely because it is advertised as a modern procedure.
The first question should be whether your eyes are suitable.
Busan Vision Clinic offers comprehensive evaluation for SMILE Pro, LASIK, LASEK, ICL, and other vision-correction options.

How Much Does High-Myopia SMILE Pro Cost in Korea?
Why Prices Vary
The cost of refractive surgery can depend on:
- Treatment type
- Laser technology
- Diagnostic testing
- Prescription complexity
- Additional eye treatment
- Medications
- Follow-up care
- Clinic-specific packages
High myopia may require more extensive diagnostic evaluation, particularly when the surgeon needs to compare several treatment options.
Should You Choose Based on Price?
Cost should not be the primary factor when choosing treatment for high myopia.
A more useful comparison considers:
- Diagnostic quality
- Ophthalmologist experience
- Available procedures
- Safety screening
- Technology
- Follow-up care
- International-patient support
Why Consider High-Myopia Treatment in Busan, Korea?
Multiple Vision-Correction Options
One advantage of seeking a comprehensive eye clinic is that you can discuss different procedures rather than assuming one treatment is appropriate.
Busan Vision Clinic offers SMILE Pro, LASIK, LASEK, ICL, and other ophthalmic services, allowing treatment planning to be based on the patient's eye condition.
Personalized Treatment Planning
For high myopia, individualized assessment is particularly important.
A clinic should not simply treat the prescription number. It should evaluate the entire eye.
This may include corneal measurements, retinal assessment, tear-film evaluation, eye pressure, and other diagnostic tests.
Questions to Ask Before Choosing SMILE Pro for High Myopia
Important Consultation Questions
Before surgery, consider asking:
- Is my prescription within the suitable SMILE Pro range?
- Is my corneal thickness sufficient?
- Is my corneal shape regular?
- How much corneal tissue will be affected?
- Is my prescription stable?
- Is my retina healthy?
- Would I be a better candidate for ICL?
- What are the expected benefits and limitations?
- How long should I stay in Korea after surgery?
- What follow-up will I need after returning home?
These questions can help you make a decision based on your actual eye health rather than marketing claims.
SMILE Pro or ICL for High Myopia: Which Is Better?
When SMILE Pro May Be Considered
SMILE Pro may be considered when:
- Myopia falls within the appropriate treatment range
- The prescription is stable
- Corneal thickness is suitable
- Corneal shape is healthy
- Overall eye health is appropriate
- The patient prefers a small-incision laser procedure
When ICL May Be Considered
ICL may be considered when:
- Myopia is relatively high
- Corneal thickness makes laser treatment less suitable
- The prescription may be outside an appropriate SMILE Pro range
- Preserving corneal tissue is important
- The patient's eye anatomy is suitable for an implantable lens
The final decision should be made after a comprehensive examination.
Conclusion
So, is SMILE Pro suitable for high myopia in Korea?
It can be suitable for some patients, but high myopia requires careful evaluation. The prescription number alone cannot determine whether SMILE Pro is safe or appropriate.
For suitable patients, SMILE Pro offers a small-incision, flapless approach to correcting myopia and certain types of astigmatism. However, patients with very high prescriptions, thin corneas, irregular corneal shape, or other concerns may be better candidates for an alternative such as ICL.
This is why a comprehensive eye examination is the most important first step.
If you are considering SMILE Pro for high myopia in Korea, discuss your prescription, corneal thickness, corneal shape, retinal health, and alternative procedures with an experienced ophthalmologist. For international patients traveling to Busan, allow enough time for diagnostic testing and postoperative follow-up before returning home.
FAQs
Can SMILE Pro correct high myopia?
Yes, SMILE Pro can correct certain levels of myopia, but suitability depends on the prescription, corneal anatomy, eye health, and applicable treatment range. High-myopia patients may also need to consider ICL.
What is the highest prescription SMILE Pro can correct?
Treatment limits vary by device, indication, and regulatory jurisdiction. Current U.S. FDA labeling for the VisuMax system includes spherical refractive error up to -10.00 D under specified conditions.
Is SMILE Pro suitable for -10.00 D myopia?
It may fall within the current U.S. FDA-labeled range under specific conditions, but that does not guarantee individual eligibility. Corneal thickness, shape, astigmatism, prescription stability, and overall eye health must also be evaluated.
Is ICL better than SMILE Pro for high myopia?
Not necessarily. ICL may be considered for some patients with high myopia, particularly when laser correction is less suitable. SMILE Pro may be appropriate for other patients. The better option depends on individual eye anatomy.
Can I have SMILE Pro if I have thin corneas and high myopia?
Thin corneas combined with high myopia may make laser correction less suitable. In such cases, an ophthalmologist may discuss ICL or another alternative.
Does SMILE Pro remove the risks of high myopia?
No. SMILE Pro corrects the refractive error by changing the cornea, but it does not necessarily eliminate structural risks associated with high myopia. Regular eye examinations may still be important.
