Treatment Overview
Gradient Aspheric Multifocal Lens Implantation in Korea is a premium cataract and refractive procedure designed to provide smooth, natural vision across multiple distances—near, intermediate, and far—by combining gradient refractive power and aspheric optical design. This innovative intraocular lens (IOL) balances light distribution intelligently, ensuring excellent contrast sensitivity and minimal visual disturbances.
The aspheric multifocal surface enhances image sharpness by reducing spherical aberrations, while the gradient refractive structure ensures a seamless transition between different focal points. Korean ophthalmology centers integrate this advanced IOL technology with AI-guided surgical planning, femtosecond laser-assisted cataract surgery (FLACS), and digital centration systems to deliver precise alignment, stable results, and long-lasting clarity.
Purpose & Benefits
Purpose
- Replace the natural or cataractous lens with a gradient aspheric multifocal intraocular lens for enhanced clarity across all visual ranges.
- Correct presbyopia, myopia, hyperopia, and mild astigmatism.
- Improve optical performance, especially in low-light conditions.
- Provide a natural depth of field without dependency on glasses or contact lenses.
Benefits
- Full-Range Vision: Clear vision for reading, computer work, and distance viewing.
- Aspheric Precision: Reduces spherical aberrations, improving contrast and focus quality.
- Smooth Visual Transitions: Gradient optical design minimizes image jumps or distortions.
- High Visual Comfort: Low incidence of glare and halos, even at night.
- Enhanced Depth Perception: Provides stable focus and natural visual balance.
- Long-Term Clarity: Premium lens materials maintain optical transparency for decades.
Ideal Candidates
Gradient Aspheric Multifocal Lens Implantation in Korea is ideal for:
- Cataract patients seeking sharp vision at all distances.
- Adults aged 40 years or older with presbyopia desiring glasses-free living.
- Refractive Lens Exchange (RLE) candidates wanting long-term correction and visual comfort.
- Patients with healthy corneas, stable retina, and balanced ocular anatomy.
- Individuals looking for a premium, natural-feeling multifocal solution with smooth adaptation.
Possible Risks & Complications
The procedure is highly safe, but mild temporary side effects may occur:
- Mild glare or halos: Typically diminish as neural adaptation occurs.
- Temporary visual fluctuation: Common during the early postoperative phase.
- Dry eyes or irritation: Easily treated with lubricating drops.
- Residual refractive error: Rare and correctable with fine-tuning or enhancement procedures.
- Posterior Capsular Opacification (PCO): May develop later and is treated with a YAG laser.
Korean ophthalmologists minimize risks using AI-calibrated planning, OCT-guided imaging, and laser precision to achieve sub-micron accuracy in IOL placement and centration.
Surgical Techniques
- AI-Guided Ocular Biometry:
Measures corneal curvature, axial length, and anterior chamber depth to calculate IOL power with perfect precision. - Femtosecond Laser-Assisted Cataract Surgery (FLACS):
Performs bladeless, laser-guided incisions, lens fragmentation, and capsulotomy for optimal IOL positioning. - Digital Centration & Alignment:
Ensures accurate lens alignment with the eye’s visual axis for maximum optical performance. - Micro-Incision Phacoemulsification:
Removes the natural lens through a 2.0 mm incision, minimizing trauma and speeding recovery. - OCT-Guided Intraoperative Imaging:
Real-time imaging confirms IOL centration, depth, and alignment accuracy. - Wavefront-Controlled Aberration Management:
Customizes the optical profile to optimize focus, contrast, and depth of vision.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Comprehensive Eye Evaluation:
Detailed analysis of visual acuity, corneal topography, axial length, and macular OCT to select the optimal gradient aspheric multifocal IOL model.
Step 2 – Surgical Planning:
AI-assisted calculation of IOL power, optical gradient, and visual target (distance, intermediate, or balanced focus).
Step 3 – Cataract Extraction or Lens Removal:
Performed using femtosecond laser-assisted or micro-incision phacoemulsification techniques for precision and safety.
Step 4 – IOL Implantation:
The gradient aspheric multifocal IOL is inserted into the capsular bag under digital centration and OCT guidance.
Step 5 – Postoperative Monitoring:
Follow-ups ensure lens stability, proper neural adaptation, and long-term clarity.
Treatment Duration: 15–25 minutes per eye
Setting: Outpatient (same-day discharge)
Recovery & After-Care
After-Care Guidelines
- Use antibiotic and anti-inflammatory drops for 2–4 weeks.
- Avoid eye rubbing, swimming, or strenuous activities for one week.
- Wear UV-protective sunglasses outdoors.
- Use artificial tears for dryness or mild irritation.
- Attend follow-up appointments at Day 1, Week 1, and Month 1 for optical verification.
Recovery Timeline
- Days 1–3: Brighter, clearer vision with mild sensitivity.
- Week 1: Distance and intermediate vision stabilize.
- Weeks 2–4: Near focus sharpens; full visual range achieved.
- 1–3 Months: Neural adaptation complete and long-term visual comfort established.
