Treatment Overview
Diffractive Optic Multifocal Lens Surgery in Korea is a premium cataract and refractive procedure that uses advanced diffractive optical design to provide seamless vision across all distances—near, intermediate, and far. This type of intraocular lens (IOL) incorporates multiple diffractive zones on its surface, allowing the eye to focus light precisely on the retina from various focal points.
Korean ophthalmology centers are global pioneers in applying AI-powered biometry, femtosecond laser-assisted cataract surgery (FLACS), and digital centration systems to ensure the diffractive lens is perfectly aligned and balanced. The result is crisp, natural, and spectacle-free vision, even in challenging lighting conditions.
Purpose & Benefits
Purpose
- Replace the natural or cataract-affected lens with a diffractive multifocal intraocular lens that restores high-quality vision at all distances.
- Correct presbyopia, myopia, hyperopia, and mild astigmatism in one precise procedure.
- Provide patients with continuous, natural visual focus for near, intermediate, and distance tasks.
Benefits
- Full-Range Vision: Clear focus at multiple distances for reading, computer use, and driving.
- Enhanced Light Efficiency: Diffractive optics optimize light distribution for sharp, contrast-rich images.
- Smooth Adaptation: Advanced design minimizes glare and halos compared to older multifocal models.
- High Visual Comfort: Ideal for patients with active lifestyles and frequent digital device use.
- Reduced Dependence on Glasses: Provides visual freedom for most daily tasks.
- Long-Term Clarity: Premium materials resist degradation, ensuring consistent optical performance over decades.
Ideal Candidates
Diffractive Optic Multifocal Lens Surgery in Korea is ideal for:
- Cataract patients who desire premium vision correction at all focal ranges.
- Adults aged 40 years or older with presbyopia seeking spectacle independence.
- Individuals considering Refractive Lens Exchange (RLE) for permanent visual enhancement.
- Patients with regular corneal shape, healthy macula, and stable ocular structures.
- Those motivated for natural, multifocal adaptation and premium optical quality.
Possible Risks & Complications
The surgery is highly safe, but temporary side effects may occur:
- Halos or glare at night: Typically improve with neuroadaptation.
- Mild dry eyes or irritation: Common postoperatively, manageable with lubricating drops.
- Temporary blurred vision: Normal during early recovery.
- Residual refractive error: Rare; can be corrected with fine-tuning or laser enhancement.
- Posterior Capsular Opacification (PCO): Can occur months later; easily treated with YAG laser.
Korean surgeons reduce risks through AI-calibrated measurements, laser precision, and digital centration verification to ensure the best possible outcomes.
Surgical Techniques
- AI-Guided Ocular Biometry:
Calculates exact IOL power, centration, and optical axis for perfect diffractive lens performance. - Femtosecond Laser-Assisted Cataract Surgery (FLACS):
Provides micrometer precision in corneal incision, capsulotomy, and lens segmentation for optimal placement. - Micro-Incision Phacoemulsification:
Removes the natural lens through a tiny incision (~2.0 mm), minimizing trauma and speeding recovery. - Digital Centration and Axis Alignment:
Ensures perfect IOL alignment with the visual axis for optimal optical clarity. - OCT-Guided Intraoperative Imaging:
Allows real-time verification of IOL position and orientation. - Wavefront-Controlled Aberration Management:
Reduces spherical and higher-order aberrations, enhancing sharpness and contrast. - Hybrid Diffractive-Refractive Optics (Optional):
Combines diffractive precision with refractive zones for balanced light distribution and natural vision transitions.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Comprehensive Eye Evaluation:
Includes corneal topography, axial length measurement, macular OCT, and AI-based optical simulation to choose the ideal diffractive multifocal lens.
Step 2 – Surgical Planning:
Customized IOL power calculation and visual target selection (distance, near, or blended focus).
Step 3 – Cataract Extraction or Lens Removal:
Performed using femtosecond laser-assisted or micro-incision phacoemulsification for precision and control.
Step 4 – IOL Implantation:
The diffractive multifocal lens is folded and inserted into the capsular bag with digital centration and axis tracking.
Step 5 – Postoperative Monitoring:
Follow-up visits ensure visual stability, alignment accuracy, and complete neural adaptation.
Treatment Duration: 15–25 minutes per eye
Setting: Outpatient (same-day discharge)
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic and anti-inflammatory drops for 2–4 weeks.
- Avoid eye rubbing, swimming, or heavy exercise for one week.
- Wear UV-protective sunglasses outdoors.
- Use artificial tears for temporary dryness or discomfort.
- Attend follow-ups at Day 1, Week 1, and Month 1 to ensure optical optimization.
Recovery Timeline
- Days 1–3: Vision becomes clearer and brighter; mild sensitivity possible.
- Week 1: Distance and intermediate vision stabilize; near focus sharpens gradually.
- Weeks 2–4: Full visual range established; halos and glare diminish.
- 1–3 Months: Complete neural adaptation and optimal clarity achieved.
