Multifocal Lens Implants in Seomyeon, Busan

Multifocal lens implants are premium intraocular lenses that split or extend focus so you can see at distance, intermediate and often near ranges after cataract or lens replacement surgery, reducing dependence on glasses. In Seomyeon, eye clinics assess suitability with detailed measurements before a 15–30 minute procedure per eye. Most people adapt over several weeks, though night halos are common.

What are multifocal lens implants?

Standard (monofocal) intraocular lenses focus at one distance, so most people still need reading glasses after cataract surgery. Multifocal and trifocal lenses (다초점 인공수정체) use optical rings to divide incoming light between distance, intermediate and near focus. Extended depth of focus (EDOF) lenses stretch the range of clear vision from distance to intermediate with fewer halos, though near vision may need occasional readers.

Who is it for?

  • People having cataract surgery who want to minimise glasses use
  • Adults in their late forties or older considering refractive lens exchange for presbyopia
  • Those with otherwise healthy eyes and realistic expectations

Multifocals are less suitable with macular disease, advanced glaucoma, significant dry eye, irregular corneas, or for people whose work depends on night driving or very high-contrast vision.

What happens at the clinic

  1. Detailed workup: biometry, corneal topography, measurement of corneal aberrations, macular OCT scan and tear film assessment.
  2. Lifestyle discussion: reading, computer use, driving and hobbies guide the choice between trifocal, EDOF or monofocal options.
  3. Surgery: same steps as cataract surgery, with the premium lens implanted in the capsule.
  4. Second eye: typically treated days to weeks later.
  5. Adaptation follow-up: visits check healing, vision at all distances and any residual prescription.

Recovery and aftercare

Early recovery is similar to standard cataract surgery: drops for several weeks, no eye rubbing and avoiding swimming early on. The brain needs time to adapt to multifocal optics; near vision and halo perception typically improve over several weeks to months. Treating dry eye helps optimise sharpness.

Risks and side effects

Besides general cataract surgery risks, multifocal lenses can cause halos, glare, reduced contrast in dim light and, occasionally, dissatisfaction leading to lens exchange. A small residual prescription may need laser touch-up or glasses.

Choosing a clinic for multifocal lenses in Seomyeon

  • Ask which specific lens models are offered and why one suits your lifestyle.
  • Ask whether a macular OCT and corneal aberration test are part of the screening.
  • Ask how halos and adaptation are managed, and what happens if you cannot adapt.
  • Ask whether laser enhancement is available if a small prescription remains.
  • Get a clear written breakdown of lens and surgery costs.

Planning your stay

Allow time for both eyes and early follow-ups, often a couple of weeks. Seomyeon's location at the Line 1 and 2 interchange simplifies repeat visits.

Key facts

  • Used in: cataract surgery or refractive lens exchange
  • Types: bifocal, trifocal, extended depth of focus (EDOF); toric versions for astigmatism
  • Goal: reduced dependence on reading and distance glasses
  • Procedure time: about 15–30 minutes per eye
  • Common side effect: halos or glare around lights at night
  • Adaptation: usually several weeks to a few months
  • Typical NHI coverage: premium lens cost is generally paid privately

Frequently asked questions

Will I need glasses after multifocal lens implants?

Many people rarely need glasses, but some still use readers for very small print or glasses for night driving. Results depend on lens type and individual eyes.

What are halos and do they go away?

Halos are rings around lights at night, common with multifocal lenses. They usually become less noticeable as the brain adapts over months, though they may not disappear completely.

Trifocal or EDOF lens: which is better?

Trifocals provide better near vision but more halos; EDOF lenses offer smoother distance-to-intermediate vision with fewer halos but weaker near focus. Lifestyle guides the choice.

Can I get multifocal lenses without having cataracts?

Yes, through refractive lens exchange, usually considered for people with presbyopia in their late forties or older. It carries the same surgical risks as cataract surgery.

Are multifocal lenses covered by insurance in Korea?

The premium lens portion is generally paid privately. Ask the clinic for a written estimate covering the lens, surgery and follow-up.
