EDOF Lens in Korea: Cost, Candidacy & Recovery
What is an EDOF lens?
An EDOF lens is an artificial intraocular lens (IOL) designed to give a continuous range of focus rather than one or two sharp focal points. It replaces your natural lens in cataract surgery or in refractive lens exchange.
A standard monofocal IOL is set for one distance, usually far. A multifocal (bifocal or trifocal) IOL splits light into separate focal points for far, intermediate and near. An EDOF lens sits between the two: it elongates the focal zone so that distance and intermediate tasks, such as a computer screen, a car dashboard or cooking, are clear, while near reading may still need weak glasses. Well-known examples are TECNIS Symfony, which uses a diffractive echelette design, and AcrySof IQ Vivity, a non-diffractive wavefront-shaping design.
How does an EDOF lens compare with monofocal and multifocal lenses?
The trade-off is range of vision versus night-time visual disturbances.
| Lens type | Distance | Intermediate | Near | Halos and glare |
|---|---|---|---|---|
| Monofocal | Excellent | Limited | Glasses needed | Least |
| EDOF | Excellent | Good | Fair; readers for fine print | Low to moderate |
| Trifocal / multifocal | Excellent | Good | Good | Most common |
| Monovision (monofocal) | One eye | Fair | Other eye | Low; less depth perception |
EDOF lenses also differ from each other. In a randomised, double-blind trial of 69 patients (Scheepers and Hall, Journal of Cataract & Refractive Surgery, 2023), Symfony and Vivity gave comparably good distance, intermediate and near acuity at three months, but moderate or severe starbursts were reported by 34% of Symfony patients versus 8.8% with Vivity, and halos by 17% versus 0%. For a wider comparison, see monofocal vs multifocal IOL. A 2021 analysis of US FDA approval-trial data (Schallhorn, Journal of Refractive Surgery) found both EDOF and multifocal lenses matched monofocals for distance and beat them for intermediate and near, but with more reports of glare, halos and starbursts than monofocal controls.
How much does an EDOF lens cost in Seoul?
EDOF lenses are priced as premium lenses. Seoul clinics serving international patients typically quote about ₩3.5 million to ₩6.5 million per eye for premium-lens surgery, approximately $2,500–$4,800 at ₩1,350–₩1,400 per dollar, with laser-assisted surgery at the upper end. Prices are per eye, so both eyes roughly double the total. Premium lenses are non-covered (비급여) in Korea, and government price disclosures show very wide variation in what clinics charge for the lens itself: in the Ministry of Health and Welfare and HIRA disclosure reported in September 2024, multifocal cataract-lens fees ranged from ₩290,000 to ₩6.8 million, with a median of ₩2.2 million. We did not find a separately published EDOF-only price range, so ask for an itemised quote naming the lens model. Our premium lens cost guide and cataract cost guide explain package contents.
How do I choose between EDOF, trifocal and monovision?
Start with how you spend your day. If most of your waking hours are spent at a screen, driving, or moving around the house and you can accept readers for small print, an EDOF lens is a reasonable middle path. If you read a lot of fine print and want the best chance of no glasses at all, a trifocal may suit you better, at the cost of more halos. If you are sensitive to night glare or have mild eye disease, monofocal lenses set for monovision (one eye for distance, one slightly near) are another option; see monovision in Korea.
Bring your hobbies and job into the consultation. Professional night drivers, pilots and people who need precise depth perception should raise this early. Ask the surgeon which lens model they use most and why, and whether a toric version is needed for your astigmatism. A good clinic will also check your tear film first, because dry eye can make any premium lens look worse; read dry eye treatment in Korea if you already have symptoms.
Who is a good candidate for an EDOF lens?
EDOF lenses suit people who want spectacle-free distance and intermediate vision and are willing to use readers occasionally.
- Adults with cataract, or presbyopic adults (usually 50+) considering lens exchange
- Heavy computer, dashboard or household-task users
- Night drivers worried about halos from full multifocals
- Healthy retina and macula, and a regular cornea
They are less suitable for people with significant macular disease, advanced glaucoma, irregular astigmatism, or a strong need for fine near vision without glasses. Astigmatism can often be corrected with a toric EDOF version. Read presbyopia treatment in Korea to compare non-lens options.
What is recovery like?
Lens surgery itself takes about 15–30 minutes per eye under numbing drops, and most people see well enough for daily life within a few days.
| Time | What to expect |
|---|---|
| Day 1 | Check-up; blurry but improving vision |
| Week 1 | Drops several times a day; avoid rubbing and swimming |
| Weeks 1–4 | Second eye often treated; intermediate vision improves as both eyes work together |
| 1–3 months | Brain adapts to the new optics; mild halos usually lessen |
International patients commonly stay about 4–7 days for one or both eyes so the surgeon can check each eye before the flight home.
What are the risks?
Risks include infection (rare but serious), inflammation, raised eye pressure, retinal detachment, posterior capsule clouding that may need a YAG laser later, and visual disturbances such as halos, starbursts or reduced contrast. A small number of people are unhappy with the quality of vision and need a lens exchange. Lens removal is permanent; the natural lens cannot be restored. This is general information; get a full exam, including retinal imaging, and an ophthalmologist's advice.

FAQ
Frequently asked questions
Is an EDOF lens better than a multifocal lens?
Neither is better for everyone. EDOF lenses usually cause fewer halos but give less near vision; trifocals give more reading range with more night-time disturbance.
Will I need reading glasses with an EDOF lens?
Many people read phones and menus comfortably but still use readers for small print or dim light. Outcomes vary with the lens model and your eyes.
How much does an EDOF lens cost in Korea per eye?
Premium-lens surgery in Seoul typically costs about ₩3.5M–₩6.5M per eye (approximately $2,500–$4,800) in 2026. Confirm the exact lens model in your quote.
Can EDOF lenses correct astigmatism?
Toric versions of some EDOF lenses correct regular astigmatism. Your surgeon will confirm suitability from corneal scans.
How long should I stay in Seoul for EDOF surgery?
Plan about 4–7 days, longer if both eyes are done on separate days.
