Treatment Overview
Cataract Surgery with Extended Depth of Focus (EDOF) Intraocular Lens (IOL) Implantation in Korea is a premium, next-generation vision restoration procedure designed to provide continuous clear vision across a wide range of distances—far, intermediate, and functional near—after cataract removal.
Unlike traditional monofocal or bifocal lenses, EDOF IOLs extend the eye’s natural depth of focus by smoothing the transition between focal points, offering crisp vision without the distinct zones or light-splitting found in multifocal designs. This reduces visual disturbances such as glare and halos while improving intermediate vision clarity (e.g., for computer and daily tasks).
Korean ophthalmologists use AI-calibrated ocular biometry, femtosecond laser-assisted cataract extraction, and wavefront-guided IOL alignment systems to ensure exceptional precision.
EDOF IOL surgery in Korea represents the perfect synergy of advanced optics, precision microsurgery, and AI-driven customization, delivering natural, high-quality vision for patients seeking a seamless visual experience.
Purpose & Benefits
Purpose
- Remove the cataract-affected lens and replace it with an EDOF intraocular lens.
- Provide a continuous range of clear vision from far to intermediate distances.
- Reduce dependence on reading glasses while maintaining optimal distance vision.
- Minimize visual side effects such as glare and halo compared to multifocal lenses.
- Enhance overall visual comfort for daily activities and screen use.
Benefits
- Seamless Vision Range: Clear focus for driving, computer work, and daily activities.
- Reduced Visual Disturbance: Fewer halos and glare than multifocal IOLs.
- Natural Visual Quality: Maintains excellent contrast sensitivity and light transmission.
- Precision Personalization: AI-guided IOL power calculation ensures tailored results.
- Fast, Comfortable Recovery: Performed via minimally invasive micro-incision surgery.
- Long-Term Stability: EDOF lenses are biocompatible and designed for lifetime performance.
Ideal Candidates
EDOF Cataract Surgery in Korea is ideal for:
- Patients with age-related cataracts seeking a broader visual range.
- Individuals who frequently use digital screens or perform intermediate tasks.
- Those desiring reduced dependence on glasses without multifocal side effects.
- Patients with stable corneal health and no major retinal pathology.
- Individuals preferring natural, continuous vision with minimal optical artifacts.
Possible Risks & Complications
The procedure is highly safe and precise, but mild or transient effects may occur:
- Temporary Light Sensitivity or Blurriness: Common during initial adaptation.
- Mild Halos or Glare: Less frequent than with multifocal lenses and often diminish over time.
- Dryness or Irritation: Temporary; managed with artificial tears.
- Residual Refractive Error: Correctable with minor laser enhancement if needed.
Korean ophthalmologists mitigate risks through real-time IOL alignment imaging, AI-driven refractive calculations, and postoperative stability monitoring using advanced optical coherence tomography (OCT).
Techniques & Technology Used
Core Techniques
- Femtosecond Laser-Assisted Cataract Surgery: Creates precise incisions and softens the cataract for effortless removal.
- AI-Guided Biometry (IOLMaster 700 / Lenstar 900): Determines exact IOL power and centration.
- Wavefront Aberrometry: Measures and corrects higher-order visual aberrations.
- Micro-Incision Phacoemulsification (MICS): Minimally invasive removal technique for fast healing.
- OCT-Guided Intraoperative Imaging: Ensures precise IOL placement and centration.
- Premium EDOF Lens Technology: Lenses such as Alcon AcrySof IQ Vivity, Tecnis Symfony, and Zeiss AT LARA are widely used in Korean clinics.
These advanced technologies make EDOF IOL surgery in Korea one of the most refined forms of refractive cataract surgery worldwide.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Evaluation:
Comprehensive diagnostics including ocular biometry, corneal topography, and AI-based refraction mapping to determine EDOF lens suitability.
Step 2 – Surgical Planning:
Surgeons select the most suitable EDOF IOL model and customize the refractive target (typically slight monovision for optimal range).
Step 3 – Cataract Extraction:
Performed using a femtosecond laser or ultrasound micro-incision phacoemulsification.
Step 4 – EDOF IOL Implantation:
The premium EDOF lens is folded and inserted through a 2.2 mm incision, then centered precisely with digital alignment guidance.
Step 5 – Postoperative Assessment:
Follow-up imaging confirms IOL positioning, tear film stability, and contrast sensitivity performance.
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
- Use antibiotic and anti-inflammatory drops as prescribed.
- Avoid eye rubbing, heavy exercise, and water exposure for one week.
- Protect eyes from bright sunlight with UV-blocking eyewear.
- Limit digital screen time during early recovery for optimal adaptation.
- Attend all scheduled check-ups to monitor IOL stability and visual progress.
Recovery Timeline
- Day 1–3: Initial vision improvement and light sensitivity adjustment.
- Week 1: Noticeable clarity for distance and intermediate tasks.
- Weeks 2–4: Full adaptation to EDOF range; reduced need for glasses.
- 1–3 Months: Long-term stabilization with excellent visual quality.
Results & Longevity
Expected Results
- Smooth, continuous vision from far to intermediate range.
