Treatment Overview
Nanex Crystal Multifocal (IOL) Implantation in Korea is a premium cataract and refractive lens procedure that offers patients sharp, natural, and spectacle-free vision across multiple distances. The Nanex Crystal IOL, known for its advanced multifocal optical design and aspheric wavefront correction, provides smooth transitions between near, intermediate, and distance vision while reducing halos and glare.
Korean ophthalmology centers are recognized worldwide for combining AI-powered biometry, femtosecond laser-assisted cataract surgery (FLACS), and digital centration systems to ensure perfect lens alignment and optical precision. By utilizing these technologies, Korean surgeons deliver clear, stable, and long-lasting visual outcomes for both cataract and refractive lens exchange (RLE) patients.
Purpose & Benefits
Purpose
- Replace the natural or cataract-affected lens with a Nanex Crystal Multifocal IOL that restores full-range vision.
- Correct presbyopia, myopia, hyperopia, and mild astigmatism simultaneously.
- Enhance near, intermediate, and distant vision without dependence on glasses.
- Provide a long-term, stable visual correction solution for active lifestyles.
Benefits
- Full-Range Vision: Delivers continuous, high-quality vision from reading to driving.
- Superior Optical Precision: The Nanex Crystal’s advanced diffractive-refractive optics minimize halos and glare.
- High Contrast Sensitivity: Maintains clarity in both bright and dim conditions.
- Spectacle Independence: Reduces or eliminates the need for bifocals or progressive lenses.
- Stable Vision: The hydrophobic acrylic design ensures long-term stability and lens centration.
- Smooth Adaptation: Optical transitions allow quick neural adaptation and visual comfort.
Ideal Candidates
Nanex Crystal Multifocal IOL Implantation in Korea is ideal for:
- Patients with cataracts seeking premium, multifocal visual correction.
- Adults aged 40 years or older with presbyopia who desire spectacle-free vision.
- Individuals undergoing Refractive Lens Exchange (RLE) for long-term correction.
- Patients with healthy corneas, clear retina, and stable ocular structure.
- Active professionals and digital device users seeking high-quality vision at all distances.
Possible Risks & Complications
The procedure is highly safe and precise, though mild and temporary effects can occur:
- Mild halos or glare: Typically diminish within weeks as the eyes adapt.
- Temporary blurred vision: Common during the early healing phase.
- Dry eyes or irritation: Managed with lubricating drops.
- Residual refractive error: Rare; can be corrected with laser enhancement if needed.
- Posterior Capsular Opacification (PCO): May occur later but is easily treated with a YAG laser.
Korean ophthalmologists minimize these risks through AI-based optical mapping, femtosecond laser accuracy, and OCT-guided intraoperative imaging for exact IOL positioning.
Surgical Techniques
- AI-Guided Ocular Biometry:
Precisely calculates IOL power, centration, and optical axis alignment. - Femtosecond Laser-Assisted Cataract Surgery (FLACS):
Uses a bladeless laser to perform incisions, capsulotomy, and lens fragmentation for maximum accuracy. - Digital Centration Systems:
Ensures perfect lens alignment with the eye’s visual axis for optimal clarity. - Micro-Incision Phacoemulsification:
Removes the natural lens through a 2.0 mm incision to minimize trauma and promote fast recovery. - OCT-Guided Imaging:
Provides real-time visualization during surgery for precise lens placement. - Wavefront Aberration Optimization:
Refines optical clarity by minimizing distortions and enhancing contrast sensitivity.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Comprehensive Eye Evaluation:
Includes visual acuity testing, corneal topography, axial length measurement, macular OCT, and AI-based lens simulation to determine the ideal Nanex Crystal model.
Step 2 – Surgical Planning:
Customized IOL power calculation and visual target design (distance, near, or blended focus).
Step 3 – Cataract Extraction or Lens Removal:
Performed using femtosecond laser-assisted or micro-incision phacoemulsification techniques.
Step 4 – IOL Implantation:
The foldable Nanex Crystal Multifocal IOL is inserted into the capsular bag and centered digitally for precise optical alignment.
Step 5 – Postoperative Monitoring:
Follow-ups ensure lens stability, focus accuracy, and smooth neuroadaptation.
Treatment Duration: 15–25 minutes per eye
Setting: Outpatient (same-day discharge)
Recovery & After-Care
After-Care Guidelines
- Use antibiotic and anti-inflammatory eye drops for 2–4 weeks.
- Avoid rubbing eyes, swimming, or strenuous activity for one week.
- Wear UV-protective sunglasses when outdoors.
- Use artificial tears to reduce dryness or irritation.
- Attend follow-ups at Day 1, Week 1, and Month 1 to monitor healing and alignment.
Recovery Timeline
- Days 1–3: Clearer vision with mild sensitivity.
- Week 1: Intermediate and distance vision stabilize.
- Weeks 2–4: Near vision sharpens; glare reduces.
- 1–3 Months: Full visual adaptation and stable clarity achieved.
