Multifocal IOL in Korea: Trifocal & EDOF Lens Surgery Guide

A multifocal IOL is an artificial lens with several focal zones that gives distance, intermediate and near vision after cataract surgery or refractive lens exchange. In Seoul it costs international (self-pay) patients about ₩3.5M–₩6.5M per eye (approximately $2,500–$4,800). Halos around lights at night are common at first.

Multifocal IOL in Korea: Trifocal & EDOF Lens Surgery Guide

What is a multifocal IOL?

A multifocal intraocular lens (IOL) is an artificial lens implanted during cataract surgery or refractive lens exchange. It splits incoming light into several focal points so you can see at distance, intermediate and near without glasses for most tasks.

A standard monofocal lens focuses at one distance, so most people still need reading glasses. Multifocal designs trade some contrast and night-time quality for that range. Trifocal lenses such as Alcon's AcrySof IQ PanOptix, approved by the FDA in 2019, add a dedicated intermediate focus for computer and dashboard distance.

Because light is shared between several focal points, the brain has to learn to pick the image it needs. This process, called neuroadaptation, explains why vision with a multifocal lens often keeps improving for weeks after the eye itself has healed.

What types of premium lens are offered in Korea?

Seoul clinics offer most major premium lenses, including trifocal, multifocal and extended depth of focus (EDOF) designs. Korean price listings in 2026 include PanOptix, Vivity, Synergy-type and Precizon lenses, among others.

Lens type Range of vision Night halos Glasses for reading
Monofocal One distance Minimal Usually needed
EDOF Distance and intermediate Mild Sometimes for fine print
Multifocal or trifocal Distance, intermediate and near Common at first Rarely needed
Toric versions As above, plus astigmatism As above As above

Lens brands and models change often, and not every clinic stocks every lens. Ask which specific models a clinic offers and why the surgeon recommends one for your eyes.

How much does a multifocal IOL cost in Korea?

For international patients, multifocal IOL surgery in Seoul costs about ₩3.5M–₩6.5M per eye (approximately $2,500–$4,800 per eye) self-pay, including surgery. Prices were checked in 2026.

Korean comparison sites list premium lenses from about ₩600,000 to ₩1.2M, but those figures are the lens only, before the surgery fee that Korean National Health Insurance covers for eligible residents. Foreign patients without that insurance pay the full fee, so ask for an all-in per-eye quote. See the multifocal lens cost guide, the cataract surgery cost guide and the presbyopia surgery cost guide.

Who is a good candidate for a multifocal IOL?

Good candidates have healthy eyes apart from cataract or presbyopia and strongly want to be free of glasses. Your surgeon reviews all pre-op measurements to judge suitability.

  • Healthy retina and optic nerve, without significant macular disease
  • Regular cornea with little higher-order distortion
  • Low or correctable astigmatism (toric versions exist)
  • Acceptance that some halo and glare at night is likely

People who drive a lot at night, have advanced glaucoma or macular degeneration risk, or need perfect contrast may do better with a monofocal or EDOF lens. Our pre-op eye exam guide explains the tests.

Trifocal, EDOF or monovision: how do you choose?

Choose by how you use your eyes every day. The best lens is the one whose trade-offs you can live with, not the one with the widest range on paper.

  • Trifocal or multifocal: the most freedom from reading glasses, with the most night halos. Suits people who read a lot and drive little at night.
  • EDOF: smooth distance and computer vision with milder halos, but reading glasses may still be needed for small print.
  • Monovision with monofocal lenses: one eye for distance, one for near. Fewer halos, but less depth perception; often trialled with contact lenses first.
  • Monofocal for distance: the sharpest contrast and fewest side effects, with reading glasses for near work.

Tell your surgeon about your job, hobbies and night driving. Previous LASIK, dry eye or astigmatism can also change which lens is advisable. Some surgeons combine different lens types in each eye; ask whether that approach would suit you.

What is recovery like?

Distance vision often improves within days, but the brain needs time to adapt to a multifocal lens. Most people notice halos and glare fade over the first three months.

Surgery takes about 15–30 minutes per eye under numbing drops, with the second eye often done a day or more later. Use drops as prescribed and attend all checks. Reading vision may feel weaker until both eyes are done and the brain adapts. Compare techniques in laser-assisted cataract surgery.

How should you plan multifocal lens surgery in Seoul?

Plan about 5–7 days in Seoul so both eyes can be operated on and checked. Premium lenses depend on precise measurements, so allow time for a thorough exam before surgery.

  • Bring records of any previous eye surgery, which affects lens calculations
  • Ask whether your lens model and power are in stock
  • Confirm whether the quote is per eye and includes follow-up and medicines
  • Arrange an ophthalmologist at home for later checks and any YAG laser treatment

What are the risks and drawbacks?

Every patient notices some halo or glare after a multifocal lens, according to the American Academy of Ophthalmology, and a few never fully adapt.

  • Halos, glare and starbursts, especially when driving at night
  • Reduced contrast in dim light
  • Residual prescription needing glasses or a laser touch-up
  • Posterior capsule clouding treated with YAG laser
  • Rare infection, swelling or retinal detachment
  • Rarely, lens exchange if you cannot adapt

Seek urgent care for sudden pain, worsening redness, new floaters or flashes after surgery. Results are not guaranteed. Discuss the trade-offs with an ophthalmologist and compare options in presbyopia treatment in Korea.

FAQ

Frequently asked questions

How much is a multifocal lens in Korea?

International patients typically pay about ₩3.5M–₩6.5M per eye (approximately $2,500–$4,800) self-pay, including surgery in 2026. Lower Korean listings usually show the lens price only.

Will I still need glasses with a multifocal IOL?

Most people need glasses rarely, but some still use them for fine print, dim light or night driving. Results vary by lens and eye.

Do halos go away after multifocal lens surgery?

They usually lessen over the first three months as the brain adapts. Some halo around lights at night often remains.

Trifocal or EDOF: which is better?

Trifocals give more near vision but more night halos; EDOF lenses give smoother distance and intermediate vision with fewer halos. Your lifestyle and eye health decide.

Can a multifocal lens be removed?

Yes, it can be exchanged if you cannot adapt, but this is more complex surgery with added risk.
