Treatment Overview
Penetrating Keratoplasty (PKP) in Korea is a full-thickness corneal transplant procedure designed to restore clear vision in patients with advanced keratoconus, severe corneal thinning, or scarring. During this surgery, the damaged or irregular cornea is replaced with a healthy donor corneal graft, precisely sutured into place to restore smooth curvature, transparency, and optical stability.
Korean ophthalmic surgeons employ femtosecond laser-assisted trephination, AI-guided graft alignment, and real-time optical coherence tomography (OCT) to achieve unmatched precision in graft sizing and placement. These innovations minimize astigmatism, accelerate healing, and ensure superior long-term outcomes.
Penetrating Keratoplasty in Korea represents the highest standard in full-thickness corneal transplantation — combining surgical precision, advanced technology, and regenerative healing for clear, stable, and long-lasting visual restoration.
Purpose & Benefits
Purpose
- Replace the full corneal thickness affected by keratoconus or scarring.
- Restore optical clarity and smooth corneal curvature.
- Correct irregular astigmatism and severe visual distortion.
- Strengthen the cornea and improve structural stability.
- Offer long-term restoration when other treatments are insufficient.
Benefits
- Complete Optical Restoration: Replaces all diseased corneal layers for maximum clarity.
- High Visual Potential: Delivers substantial improvement in vision quality.
- Durable Structural Reinforcement: Provides long-lasting stability and transparency.
- Advanced Surgical Precision: Femtosecond laser technology ensures perfect graft matching.
- Long-Term Results: Proven success over decades of clinical application.
- Regenerative Recovery: Promotes smooth healing and minimal scarring.
Ideal Candidates
Penetrating Keratoplasty in Korea is ideal for:
- Patients with advanced keratoconus and severe corneal thinning.
- Individuals with corneal scarring or opacities impairing vision.
- Those who have failed other treatments such as CXL, Intacs, or lamellar grafting.
- Patients seeking permanent visual rehabilitation through transplantation.
- Individuals with healthy ocular surfaces and no active inflammation.
Possible Risks & Complications
Penetrating keratoplasty is a safe and proven surgical technique, though some potential side effects may occur:
- Mild Redness or Irritation: Common during early healing stages.
- Light Sensitivity or Glare: Temporary and improves with recovery.
- Astigmatism or Vision Fluctuation: Managed with suturing adjustments or corrective lenses.
- Graft Rejection (Rare): Prevented with immunosuppressive eye drops and careful monitoring.
- Infection or Inflammation: Minimized through sterile surgical protocols and antibiotic therapy.
Korean corneal surgeons use AI-guided precision mapping, laser-cut donor matching, and real-time endothelial monitoring to minimize complications and ensure optimal outcomes.
Techniques & Technology Used
Core Techniques
- Femtosecond Laser Trephination: Ensures perfectly circular grafts and smooth wound edges.
- AI-Guided Donor Matching: Selects ideal graft diameter and curvature for seamless alignment.
- OCT Imaging Integration: Provides real-time depth visualization during surgery.
- Micro-Suture or Laser-Assisted Fixation: Maintains perfect graft position and reduces astigmatism.
- Regenerative Biologic Therapy: Accelerates healing and promotes cellular integration.
- Customized Suture Tension Control: Fine-tunes curvature and visual results.
These techniques make Korean PKP one of the most advanced, accurate, and visually successful full-thickness corneal transplantation procedures worldwide.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Assessment:
Comprehensive corneal imaging, topography, and endothelial evaluation determine the exact graft requirements.
Step 2 – Donor Graft Preparation:
A healthy donor cornea is laser-cut for precise size matching and curvature alignment.
Step 3 – Recipient Corneal Removal:
The diseased cornea is removed using femtosecond laser trephination for a clean, controlled incision.
Step 4 – Graft Implantation & Suturing:
The donor cornea is placed and secured with ultra-fine sutures or laser-assisted bonding.
Step 5 – Postoperative Recovery:
Regenerative drops, anti-inflammatory medication, and UV protection support healing and clarity.
Procedure Duration: 60–90 minutes per eye
Recovery Period: Initial vision improvement within 2–3 weeks; full recovery in 3–6 months.
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic, steroid, and lubricating eye drops regularly.
- Avoid rubbing or pressing on the eyes for at least one month.
- Wear protective eyewear and avoid strenuous activities.
- Attend scheduled follow-ups for suture adjustment and graft evaluation.
- Maintain proper hygiene to prevent infection.
Recovery Timeline
- Days 1–7: Redness and mild discomfort subside.
- Weeks 2–4: Vision begins to stabilize; clarity improves gradually.
- Months 1–3: Sutures adjusted for curvature optimization.
- 6–12 Months: Final vision stabilization and graft integration achieved.
Results & Longevity
Expected Results
- Clear and stable vision restored.
- Elimination of irregular astigmatism and corneal distortion.
- Strengthened and transparent corneal structure.
- Significant improvement in visual function and quality of life.
Longevity
Penetrating Keratoplasty offers long-term or lifelong visual restoration, with graft survival rates exceeding 90% in Korean clinics.
Results remain stable for 15–20 years or longer, especially with regular monitoring and regenerative post-care.
