SMILE LASIK
A minimally invasive procedure using only a 2–4mm incision
SMILE LASIK
- SMILE LASIK removes a lenticule through a small 2–4mm incision, with no corneal flap.
- The small incision is associated with comparatively less corneal nerve disruption and dry-eye burden.
- Requires dedicated equipment, so confirming the clinic's equipment is important.
- Often considered for high myopia given the minimal incision size.
SMILE LASIK removes a refractive lenticule through a small 2–4mm incision, without creating any corneal flap. Because the incision is so small, it is associated with comparatively less corneal nerve disruption and dry-eye burden, and is often considered even for high myopia due to the minimal incision size. It does require dedicated laser equipment, so confirming that a clinic actually owns the appropriate equipment matters.
How much does it cost?
roughly 2,000,000–3,000,000 KRW for both eyes
Checklist for choosing a clinic
- Dedicated equipment on-site — Confirm the clinic actually owns the SMILE-specific laser equipment.
- Surgeon experience — Ask whether the surgeon can clearly explain their experience with lenticule extraction.
- Suitability for high myopia — Confirm through pre-op exam whether your degree of myopia or astigmatism is compatible.
- Transparent total cost — Confirm the total cost, including equipment usage fees, is clearly disclosed in advance.
Frequently Asked Questions
Why does SMILE LASIK tend to cost more than LASIK or LASEK?
SMILE LASIK requires dedicated laser equipment, and the cost of acquiring, maintaining, and operating that equipment is often reflected in a higher price range compared with LASIK or LASEK. Exact pricing varies significantly by clinic, so please confirm through a consultation.
Is SMILE LASIK less painful?
Because the incision is only 2–4mm and no corneal flap is created, SMILE LASIK is generally reported as involving less discomfort during and after surgery compared with LASIK or LASEK. Individual pain perception can still vary.
What's the biggest difference between SMILE LASIK and LASIK?
LASIK creates a flap and reshapes the tissue underneath, while SMILE LASIK removes only a lenticule through a small incision with no flap at all. This means SMILE LASIK avoids flap-related risks such as displacement and is associated with less dry-eye burden.
Is SMILE LASIK possible for high myopia?
High myopia can often still be considered for SMILE LASIK if corneal thickness and residual corneal volume are sufficient. In cases of very high myopia, an implantable lens (ICL) may be more suitable depending on corneal condition, which is why a pre-operative exam is essential before any decision.
