Treatment Overview
EDoF Intraocular Lens Implantation in Korea is a premium cataract/refractive lens procedure that provides a continuous range of clear vision from distance through intermediate, with functional near vision for many tasks. EDoF optics stretch the eye’s depth-of-focus to reduce glasses dependence—especially for driving, sports, and computer work—while typically causing fewer halos/glare than classic multifocals.
Korean centers pair EDoF lenses with AI-driven biometry, femtosecond laser assistance, and digital centration systems to maximize clarity, contrast, and patient comfort.
Purpose & Benefits
Purpose
- Replace the cataractous or natural lens with an EDoF IOL to enhance distance and intermediate vision and provide usable near vision.
- Correct presbyopia along with myopia/hyperopia, and astigmatism when using a toric EDoF variant.
- Minimize reliance on glasses for most daily activities, particularly mid-range tasks.
Benefits
- Smooth distance-to-intermediate vision: Excellent for driving, screens, meetings, and daily mobility.
- Reduced photic phenomena: Typically less halo/glare than many multifocals.
- High contrast sensitivity: Aspheric, wavefront-friendly designs support crisp vision in varied lighting.
- Option to personalize near vision: Strategies like mini-monovision can boost reading performance if desired.
- Stable, long-term clarity: Premium biomaterials resist haze and glistening.
Ideal Candidates
- Cataract patients who prioritize distance and intermediate clarity with lower night-vision artifacts.
- Professionals and frequent digital users who want premium optics without full multifocal trade-offs.
- Patients open to occasional readers for fine print, or willing to consider mini-monovision for extra near power.
- Healthy ocular anatomy (regular cornea, clear macula, adequate tear film) and realistic expectations.
Possible Risks & Complications
- Residual refractive error (sphere/cylinder) requiring glasses or enhancement.
- Halos/glare may still occur, but typically milder than classic multifocals.
- Dry eye/inflammation post-op—usually transient and manageable with drops.
- Posterior Capsular Opacification (PCO) months to years later; treatable with a brief YAG laser.
- Lens rotation (toric models): minimized via precise alignment and modern haptic designs.
Techniques & Technology Used (Korea)
- AI-Guided Biometry & Planning: Barrett/modern formulas, total keratometry, corneal topography/tomography.
- Femtosecond Laser-Assisted Cataract Surgery (FLACS): Precise capsulotomy and lens fragmentation for ideal centration.
- Micro-Incision Phacoemulsification: Low-trauma removal with rapid recovery.
- Digital Centration & Intraoperative Aberrometry: Real-time verification of IOL power, axis, and tilt.
- OCT-Guided Imaging: Confirms final position for optimal EDoF performance.
Treatment Process in Korea
Step 1 – Evaluation & Counseling
Visual acuity, topography/tomography, macular OCT, tear film analysis, lifestyle assessment (screen time, night driving), and EDoF suitability discussion.
Step 2 – Surgical Planning
Choose EDoF model, consider toric if astigmatism; set target refraction (often emmetropia) or mini-monovision for added near.
Step 3 – Lens Removal
FLACS or micro-incision phaco to remove cataract with minimal energy.
Step 4 – EDoF IOL Implantation
Foldable lens inserted into the capsular bag; digital systems ensure centration/axis accuracy.
Step 5 – Post-Op Optimization
Follow-ups verify alignment, contrast, and refractive precision; fine-tune near strategy if needed.
Duration: ~15–25 minutes per eye
Setting: Outpatient, same-day discharge
Recovery & After-Care
After-Care Guidelines
- Antibiotic/anti-inflammatory drops for 2–4 weeks.
- Avoid eye rubbing, swimming, heavy exercise for 1 week.
- UV-protective sunglasses outdoors; lubricating drops for dryness.
- Follow-ups: Day 1, Week 1, Month 1 (and as advised).
Recovery Timeline
- Days 1–3: Clearer vision; mild sensitivity possible.
- Week 1: Distance/intermediate stabilize; night comfort improves.
- Weeks 2–4: Refinement of clarity and contrast; many can do most tasks without glasses.
- 1–3 Months: Final visual performance; consider micro-refinement if desired.
Results & Longevity
Expected Results
- Excellent distance/intermediate vision; functional near for many tasks.
- Lower dysphotopsia profile vs many trifocals.
- High patient satisfaction for driving, office work, and daily activities.
Longevity
- Permanent implant designed for decades of stable clarity.
- Materials and edge designs resist long-term haze and maintain centration.
