Treatment Overview
Extended Depth of Focus (EDOF) Intraocular Lens (IOL) Implant in Korea is a cutting-edge ophthalmic procedure designed to restore clear, continuous vision across far, intermediate, and functional near distances after cataract removal or refractive lens exchange.
Unlike standard monofocal lenses, which focus at only one distance, EDOF IOLs use advanced optical engineering to extend the focal range—providing smooth, uninterrupted vision and minimizing visual disturbances such as glare or halos that are often seen with multifocal lenses.
Korean ophthalmologists are global pioneers in AI-guided IOL selection, femtosecond laser-assisted cataract surgery, and wavefront-based IOL centration, ensuring exceptional precision, safety, and long-term stability.
This treatment is ideal for patients who want natural, high-quality vision across multiple distances without depending on reading glasses.
Purpose & Benefits
Purpose
- Replace the cataractous or aging natural lens with a next-generation EDOF IOL.
- Provide a continuous range of clear vision—far to intermediate—with functional near focus.
- Minimize visual aberrations and contrast loss common in multifocal lenses.
- Enhance visual comfort and independence from glasses for most daily tasks.
- Achieve long-term clarity through AI-calibrated precision surgery.
Benefits
- Seamless Visual Range: Clear vision for driving, computer use, and reading small print.
- Natural Visual Experience: No abrupt focus shifts or optical jumps.
- Reduced Halos & Glare: Ideal for night driving and low-light conditions.
- Excellent Contrast Sensitivity: Crisp and vibrant vision across lighting conditions.
- High Adaptability: Faster neural adaptation compared to multifocal IOLs.
- AI-Precision Outcomes: Customized optics for each patient’s visual profile.
Ideal Candidates
EDOF IOL Implantation in Korea is ideal for:
- Patients with cataracts or presbyopia seeking freedom from glasses.
- Individuals who want smooth, natural vision without multifocal artifacts.
- Patients who frequently use digital devices or perform intermediate tasks (e.g., computer work, cooking, office activities).
- Those seeking a premium visual correction option with minimal side effects.
- Individuals with stable corneal health and no significant retinal pathology.
Possible Risks & Complications
The procedure is highly safe and well-tolerated, but mild and temporary effects may include:
- Light Sensitivity or Glare: Typically improves with adaptation.
- Transient Blurriness: Common during early healing stages.
- Dry Eyes or Discomfort: Resolved with lubricating eye drops.
- Residual Refractive Error: Rare; can be fine-tuned with minor enhancements.
- Posterior Capsular Opacification (PCO): May occur long-term, easily treated with YAG laser.
Korean ophthalmologists minimize risks using real-time AI imaging, wavefront aberrometry, and digital alignment systems for flawless IOL centration.
Techniques & Technology Used
Core Techniques
- Femtosecond Laser-Assisted Cataract Surgery: Delivers micron-level incision precision and capsulotomy control.
- AI-Guided Ocular Biometry (IOLMaster 700 / Lenstar 900): Calculates exact IOL power and corneal curvature.
- Wavefront Aberrometry & Topography: Analyzes optical performance and higher-order aberrations.
- Micro-Incision Phacoemulsification (MICS): Allows lens removal through a 2.2 mm incision with minimal trauma.
- OCT-Based Surgical Guidance: Ensures perfect IOL centration and capsule stability.
- Premium EDOF IOL Models: Commonly used lenses include Alcon AcrySof IQ Vivity, Tecnis Symfony, and Zeiss AT LARA.
Korean clinics integrate these innovations into precision refractive workflows for unmatched accuracy and patient satisfaction.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Evaluation:
Comprehensive eye assessment including corneal topography, ocular biometry, and AI-powered visual simulations to determine EDOF IOL suitability.
Step 2 – Surgical Planning:
Ophthalmologists select the optimal IOL model and visual target (e.g., distance-dominant or mini-monovision configuration).
Step 3 – Femtosecond Laser-Assisted Lens Removal:
The cataract or natural lens is emulsified and extracted through a tiny incision.
Step 4 – EDOF IOL Implantation:
The foldable lens is inserted and positioned precisely in the capsular bag with digital alignment tools.
Step 5 – Postoperative Monitoring:
Follow-ups assess IOL positioning, ocular healing, and functional vision performance using wavefront analysis.
Treatment Duration: 20–30 minutes per eye (outpatient).
Follow-Up: 1 day • 1 week • 1 month • 3 months post-surgery.
Recovery & After-Care
After-Care Guidelines
- Apply antibiotic and anti-inflammatory drops as prescribed.
- Avoid rubbing the eye, swimming, or strenuous activity for one week.
- Use UV-protective eyewear outdoors.
- Keep eyes moist and clean with artificial tears.
- Attend scheduled follow-up appointments to ensure IOL stability and visual adaptation.
Recovery Timeline
- Day 1–3: Noticeable improvement in vision and color brightness.
- Week 1: Clear vision at distance and intermediate; mild near blurriness may persist.
- Weeks 2–4: Visual range stabilizes; reduced need for glasses.
- 1–3 Months: Full adaptation and sustained visual balance achieved.
Results & Longevity
Expected Results
- Clear, natural vision across a wide range of distances.
