Treatment Overview
Lenticule Extraction SMILE in Korea — also known simply as SMILE (Small Incision Lenticule Extraction) — is a revolutionary, flap-free laser vision correction procedure designed to reshape the cornea through a microscopic incision.
Developed as the third generation of laser vision correction after PRK and LASIK, SMILE uses a femtosecond laser to create and remove a small lens-shaped disc of corneal tissue (the “lenticule”). This changes the curvature of the cornea, correcting refractive errors such as myopia and astigmatism with extraordinary precision and minimal disruption to surrounding tissue.
Korean ophthalmology centers have elevated this technology by integrating AI-guided diagnostics, wavefront mapping, and biologic regenerative care—ensuring faster recovery, greater comfort, and sharper, longer-lasting vision.
Purpose & Benefits
Purpose
- Correct nearsightedness (myopia) and astigmatism through lenticule extraction.
- Offer a flap-free, minimally invasive alternative to LASIK.
- Preserve corneal strength, natural shape, and nerve function.
- Reduce the risk of dry eyes, glare, and flap complications.
Benefits
- Flap-Free Precision: No corneal flap—faster healing and less irritation.
- Gentle and Safe: Small incision (2–4 mm) means minimal corneal disruption.
- Enhanced Comfort: Less post-surgical dryness and foreign-body sensation.
- Rapid Recovery: Clear vision typically within 24 hours.
- Stable Long-Term Results: Maintains biomechanical strength and vision stability.
- Proven Korean Expertise: Advanced technology and internationally trained surgeons.
Ideal Candidates
Lenticule Extraction SMILE in Korea is ideal for:
- Adults aged 18 years or older with a stable prescription for at least one year.
- Patients with myopia (–1.00 D to –10.00 D) or astigmatism (up to –3.00 D).
- Individuals who prefer a flap-free, minimally invasive surgery.
- Those with dry or sensitive eyes or thin corneas unsuitable for LASIK.
- Patients seeking a quick, comfortable, and long-term vision solution.
Possible Risks & Complications
While extremely safe, mild and temporary effects can occur:
- Dryness or Mild Sensitivity: Short-term and manageable with lubricating drops.
- Light Sensitivity or Glare: Improves as corneal healing completes.
- Minor Haze or Halos: Temporary during the initial recovery.
- Under- or Over-Correction: Rare; enhancement possible if necessary.
- Infection or Inflammation: Very rare due to sterile, AI-controlled environments.
Korean surgeons minimize these risks through real-time laser tracking, tear-film diagnostics, and post-operative imaging.
Techniques & Technology Used
Core Techniques
- Femtosecond Laser Lenticule Creation: The laser creates a precise lenticule within the corneal layer.
- Micro-Incision Extraction: A small incision allows removal of the lenticule without creating a flap.
- AI-Calibrated Laser Control: Adjusts pulse energy and focus for optimal accuracy.
- Wavefront & Topography Mapping: Customizes each correction for superior clarity and contrast.
- Tear Preservation System: Maintains hydration and reduces postoperative dryness.
- Oxygen-Enhanced Healing: Promotes rapid epithelial regeneration.
Korean clinics utilize ZEISS VisuMax 800, SCHWIND ATOS, and LENSAR AI laser systems for unmatched precision and comfort.
Treatment Process in Korea
Step-by-Step Workflow
- Comprehensive Evaluation:
Corneal imaging, wavefront mapping, pachymetry, and tear-film testing determine eligibility. - Customized Surgical Planning:
AI software designs the lenticule shape and incision parameters. - Laser Lenticule Creation:
Femtosecond laser sculpts a small lenticule in the cornea within seconds. - Lenticule Extraction:
Surgeon removes the lenticule through a micro-incision, reshaping the cornea. - Surface Stabilization:
Oxygen or biologic drops help the cornea heal smoothly. - Follow-Up Care:
Post-operative exams confirm stability and visual performance.
Procedure Duration: ~10 minutes per eye.
Recovery: Most patients notice improved vision within 24 hours.
Recovery & After-Care
After-Care Guidelines
- Use prescribed medicated and lubricating drops as directed.
- Avoid rubbing eyes or applying makeup for 1 week.
- Wear sunglasses outdoors to protect from UV exposure.
- Avoid swimming, steam rooms, and saunas for 1–2 weeks.
- Attend follow-up visits for monitoring corneal healing.
Recovery Timeline
- Day 1–2: Noticeable clarity and minimal discomfort.
- Week 1: Vision stabilizes; normal activities resume.
- Weeks 2–4: Contrast and sharpness improve further.
- 1–3 Months: Final visual refinement and corneal recovery complete.
Results & Longevity
Expected Results
- Clear, sharp, natural vision with minimal dryness or irritation.
- Enhanced night vision and improved contrast sensitivity.
- Rapid, comfortable recovery.
Longevity
Lenticule Extraction SMILE offers permanent corneal reshaping and stable visual results for 15–20 years or more.
Clinical data from Korean centers show over 98 % patient satisfaction with enduring clarity and negligible regression.
