SMILE PRO vs LASIK vs LASEK in Gangnam Seoul depends on your corneal thickness, prescription, lifestyle, and eye health. SMILE PRO offers a flap-free approach with fast recovery, LASIK provides proven long-term results, and LASEK is often suitable for thinner corneas. A comprehensive eye examination determines the best procedure.
BSM Eye Care Clinic in Gangnam
Choosing between SMILE PRO, LASIK, and LASEK depends on your eye health, corneal thickness, lifestyle, occupation, and vision goals—not simply which procedure is the newest. While all three procedures are proven methods of correcting refractive errors such as myopia, astigmatism, and, in some cases, hyperopia, each has distinct advantages, recovery timelines, and suitability criteria. The best option is determined after a comprehensive eye examination performed by an experienced ophthalmologist.
Gangnam, Seoul has become one of Asia’s leading destinations for vision correction surgery, attracting international patients seeking advanced laser technology, experienced refractive surgeons, and efficient treatment schedules. Clinics in Gangnam commonly offer state-of-the-art diagnostic equipment, personalized surgical planning, and multilingual international patient services, allowing overseas visitors to complete consultations, surgery, and follow-up examinations within a relatively short stay.

What Are SMILE PRO, LASIK, and LASEK?
All three procedures are laser vision correction surgeries designed to reduce or eliminate dependence on glasses or contact lenses by reshaping the cornea so that light focuses correctly on the retina.
Although they share the same goal, the surgical techniques differ significantly.
| Procedure | How It Works | Corneal Flap | Recovery |
|---|---|---|---|
| SMILE PRO | Removes a small lenticule through a tiny incision using a femtosecond laser | No flap | Very fast |
| LASIK | Creates a corneal flap before reshaping the cornea with an excimer laser | Yes | Fast |
| LASEK | Preserves the epithelial layer before laser reshaping | No permanent flap | Slower |
Quick Answer: Which Procedure Is Best?
There is no universally “best” procedure.
Generally:
- SMILE PRO is often preferred for active individuals, athletes, and patients seeking faster recovery with minimal corneal disruption.
- LASIK remains an excellent option for many patients with suitable corneal anatomy who desire rapid visual recovery.
- LASEK may be recommended for patients with thinner corneas or those who are not ideal candidates for flap-based surgery.
The appropriate treatment should always be based on a detailed eye examination rather than patient preference alone.
What Is SMILE PRO?
SMILE PRO (Small Incision Lenticule Extraction Pro) is the newest evolution of minimally invasive laser vision correction.
Instead of creating a corneal flap, the laser forms a thin lenticule inside the cornea, which is removed through a tiny incision measuring only a few millimeters.
This preserves more of the cornea’s natural biomechanics compared with traditional flap procedures.
Advantages
- No large corneal flap
- Smaller incision
- Reduced corneal nerve disruption
- Rapid visual recovery
- Lower incidence of postoperative dry eye in appropriate patients
- Suitable for active lifestyles
Limitations
SMILE PRO may not be appropriate for every refractive error or corneal condition.
Patients with significant hyperopia or certain irregular corneal diseases may require alternative procedures.
Understanding LASIK
LASIK has been one of the world’s most widely performed refractive surgeries for decades.
The procedure involves creating a thin corneal flap using either a femtosecond laser or microkeratome.
After lifting the flap, an excimer laser reshapes the underlying cornea before repositioning the flap.
Advantages
- Excellent long-term clinical outcomes
- Fast recovery
- Minimal discomfort
- Extensive scientific evidence
- Suitable for many prescriptions
Considerations
Because LASIK involves creating a flap, surgeons evaluate:
- Corneal thickness
- Corneal stability
- Occupational risks
- Contact sports participation
Although flap complications are uncommon, preserving flap integrity remains an important consideration.
Understanding LASEK
LASEK differs significantly from LASIK.
Instead of creating a corneal flap, only the thin epithelial layer is temporarily moved before laser treatment.
The epithelium gradually heals over several days.
Advantages
- No permanent corneal flap
- Appropriate for selected thin corneas
- Preserves more stromal tissue
- Good long-term visual outcomes
Limitations
Recovery is slower.
Patients commonly experience:
- Temporary discomfort
- Light sensitivity
- Blurry vision during healing
- Several days before functional vision returns
SMILE PRO vs LASIK vs LASEK Comparison
| Feature | SMILE PRO | LASIK | LASEK |
|---|---|---|---|
| Surgical Time | Very short | Short | Short |
| Corneal Flap | No | Yes | No |
| Recovery Speed | Excellent | Excellent | Moderate |
| Initial Discomfort | Minimal | Minimal | Higher |
| Dry Eye Risk | Lower in many patients | Low to moderate | Low |
| Sports Suitability | Excellent | Good | Excellent |
| Thin Corneas | Sometimes | Limited | Often suitable |
| Vision Stabilization | Fast | Fast | Slower |
How Surgeons Decide Which Procedure Is Right
Experienced refractive surgeons evaluate multiple factors—not just prescription.
These include:
Corneal Thickness
Thin corneas may limit eligibility for LASIK.
SMILE PRO or LASEK may preserve more corneal tissue depending on individual measurements.
Corneal Shape
Advanced corneal topography evaluates:
- Keratoconus risk
- Corneal symmetry
- Irregular astigmatism
Abnormal findings may exclude laser surgery altogether.
Degree of Nearsightedness
Patients with high myopia often require careful evaluation.
In some cases, implantable collamer lenses (EVO ICL) may provide a better solution than laser surgery.
Dry Eye Assessment
Many international patients spend long hours using computers.
Pre-existing dry eye syndrome significantly influences surgical planning.
Clinics frequently perform:
- Tear break-up time
- Tear production testing
- Meibomian gland evaluation
Treating dry eye before surgery often improves postoperative comfort.
Lifestyle
Lifestyle matters.
Examples include:
Office Professionals
SMILE PRO or LASIK often provide quicker return to work.
Athletes
Contact sports participants frequently appreciate flap-free procedures.
Military Personnel
Certain occupations may have specific vision correction requirements.
