Cataract Surgery in Korea: A Seoul Surgeon's Honest Guide

Hello, I'm Dr. Kim Sun-young, Medical Director of Healing Eye Clinic in Sinnonhyeon, Gangnam, Seoul. I served as a clinical professor of cornea and cataract at a university hospital, and today I see patients who fly in from abroad every week, with English-speaking staff in the clinic.

A message we often get starts like this: "Dr. Kim, my eye doctor says I need cataract surgery. Is it safe to have it done in Korea, so far from home?"

If you are searching for cataract surgery in Korea, you are probably asking the same thing. I understand. This is your sight, and a lens that stays in your eye for life.

So let me be honest from the start: the hardest part of cataract surgery is not the operation itself — it is choosing the right lens for your eye. I'll walk you through it the way I explain it in my consulting room.

What cataract surgery in Korea actually involves

The operation is the same standard procedure used worldwide. What differs between clinics is how carefully the eye is measured, and who takes responsibility afterwards.

1. The exam decides the lens, not the brochure

Before surgery we measure eye length, corneal curvature, astigmatism, corneal endothelial cells, the macula and the optic nerve.

These numbers set the power and type of your new lens. Choosing a lens before the exam is like buying shoes before measuring your feet.

My rule: I don't name a lens until I've seen your numbers.

2. The surgery is short; the planning is long

Through a 2–3mm incision, the clouded lens is broken up with ultrasound and removed. A folded lens goes in and opens where the old one sat.

It is done under numbing drops, the incision usually seals without stitches, and you go home the same day. Vision often looks noticeably brighter that day.

3. Monofocal or premium — this is the real decision

A monofocal lens gives one sharp distance and clean night vision. A multifocal lens covers far, middle and near, which can reduce your need for glasses.

A multifocal lens is not automatically the better lens. If you drive a lot at night, or your macula isn't perfectly healthy, I may advise a monofocal.

4. Follow-up has to be planned before you fly

We check the eye the day after surgery. After that, your 1-week, 1-month and 3-month checks can be done by an eye doctor at home.

We give you a written record of the lens model, its power and your measurements, so the next doctor isn't guessing.

If you are unsure whether it's time yet, I explain the timing question in when to have cataract surgery.

Why the surgeon who examines you should be the one who operates

At Healing Eye Clinic, the same surgeon does your exam, chooses your lens with you, operates and checks you afterwards.

The person who measured your eye knows why that lens was chosen. That knowledge shouldn't be handed over halfway.

These are not boasts but facts you can check. Foreign patients pay the same price as Korean patients. We hold a Google rating of 4.8 from 154 reviews. I am a member of the European Society of Cataract and Refractive Surgeons (ESCRS), and the clinic runs a lifetime surgery responsibility program.

So which lens is right for me?

This table is how I start the conversation. The final answer comes from your exam.

You can read how each lens works on our cataract surgery page and our presbyopia and cataract page. My longer comparison is in monofocal vs multifocal IOL for cataract.

Here are our published prices for reference. A full breakdown is in cataract surgery cost in Korea and on our price page.

Side effects, and when I'd tell you to wait

• Grittiness and watering: common for the first days and usually settles.
• Glare and halos: more noticeable with multifocal lenses, and many patients adapt over time. Individual results vary.
• After-cataract: the membrane behind the lens can haze later; a short laser procedure clears it.
• Infection: rare, but no surgeon can promise zero risk. That's why the drops and checks matter.

What the first weeks usually feel like is covered in cataract surgery recovery time.

If your cataract is mild and not bothering daily life, I will usually tell you to wait. Cataract surgery is rarely an emergency. If you have macular disease or glaucoma, the result may be less sharp than you hope, and I'll say so before you book anything.

Planning your trip

• Exam, surgery, next-day check: this is the minimum. Doing both eyes changes the length, so we plan it after your exam.
• Flexible flights: choose tickets you can change by a day or two.
• Medications: bring a list, especially blood thinners, diabetes medicines and prostate medicines.
• Your home doctor: book your local 1-week check before you leave.
• Getting here: we are one minute from Sinnonhyeon Station, about 70 minutes from Incheon Airport.

Don't book the procedure yet — book the exam

My advice is simple. Don't choose a clinic by price, and don't choose a lens by its name.

Send us your age, your current diagnosis and any recent eye reports on WhatsApp. If your exam shows that surgery isn't the right step yet, or that another lens suits you better, I will tell you plainly.

I look forward to seeing your eyes in Seoul.
