~15–20 min (per eye)
Daily life in days; settles gradually
If the world has slowly gone hazy, colors look faded, and night driving has become stressful, it's very likely a cataract. Cataract surgery removes your own clouded lens and replaces it with a clear intraocular lens (IOL), bringing your blurred vision back into focus. The procedure itself is short per eye, and many patients who travel all the way to Korea have both eyes taken care of in a single visit. I, Dr. Kim Sun-young, personally guide you from the exam through surgery and lifelong aftercare.
Surgery that removes the clouded natural lens and replaces it with a clear intraocular lens to restore vision. With a premium IOL, cataract treatment can also correct presbyopia and astigmatism in one step — efficient for patients traveling from abroad.

Is it right for me?
A good fit if
- Someone whose exam confirms lens clouding, and whose vision stays hazy or washed-out even with new glasses, with glare or halos getting in the way of daily life.
- Adults in their 40s–50s and beyond who see oncoming headlights smear at night, find print on books or phones dim, and feel their quality of work and life slipping.
- Someone who, while removing the cataract, wants one surgery to also reduce their everyday dependence on glasses and is considering premium IOLs such as multifocal or toric lenses.
- Patients living abroad who can't come back often, and want a precise exam and surgery done somewhere they can trust, within a short trip.
- Anyone who wants the exam, surgery, and recovery explained with an interpreter in their own language, and one surgeon responsible from start to finish.
Consider carefully if
- If the clouding is still mild and isn't really interfering with daily life, it's often better to watch it and decide on timing together rather than rush. Cataract surgery is frequently not an emergency.
- If other eye conditions are present — macular degeneration, glaucoma, corneal endothelial damage — even with an IOL the result may not be as crisp as hoped. Multifocal lenses in particular can make night glare and halos more bothersome, so depending on your exam I sometimes recommend a monofocal lens.
- Uncontrolled diabetes, autoimmune disease, or certain medications (for example some prostate drugs) can affect surgery and healing, so being open about them lets us build a safe plan.
1What cataract surgery is — swapping a clouded lens for a clear one
Inside the eye is a lens — the 'crystalline lens' — that focuses light like a camera lens. With age its proteins break down and it turns cloudy; that is a cataract. No drops or glasses can reverse it; the only true fix is to remove the clouded lens itself and replace it with a new intraocular lens. Because the IOL stays clear and lasts a lifetime, deciding 'when, and with which lens' is the heart of the whole process.
2Phacoemulsification — a small incision, precise removal
Modern cataract surgery's standard is phacoemulsification: a 2–3mm micro-incision in the cornea, ultrasound to break the clouded lens into tiny pieces and gently aspirate them, then an IOL placed where it sat. The incision is small enough that it usually needs no stitches, it's done under topical (drop) anesthesia, and you go home the same day with no hospital stay. But the outcome depends not only on hand skill but heavily on the precision of pre-op measurements. That's why I scrutinize the step before surgery — the biometry that measures eye length, corneal curvature, and astigmatism axis — even more than the surgery itself.
3Choosing the IOL — monofocal vs premium (multifocal / toric)
IOLs fall mainly into three kinds: a 'monofocal' that puts one distance in sharp focus; a 'multifocal' that lets you see far, intermediate, and near together to cut your reliance on glasses; and a 'toric' lens that corrects astigmatism. Monofocals give clean night vision and good contrast, suiting people who drive a lot at night; multifocals delight those who want to be free of reading glasses, though a minority notice night glare. There is no single right answer — it depends on your eye and your life. I look at pupil size, corneal astigmatism, macula and optic nerve, and listen to your day — driving, reading, close work — and we decide together. If your exam doesn't favor a multifocal, I'll tell you honestly and recommend a monofocal.
4Safety — what we check, and what we promise
Before surgery I don't just check whether a cataract exists. I carefully assess corneal endothelial cell count, the health of the macula and optic nerve, eye pressure, the tear film, pupil response, and biometry in both eyes — so we can estimate in advance how crisp vision can actually become with an IOL. That way we picture a realistic result, not a vague hope. No surgery can claim zero risk of infection or after-cataract, but precise pre-op testing, sterile surgery, and thorough follow-up lower it. With our lifetime surgery guarantee, we stay responsible for your eyes long after the operation.
5One trip, designed for patients coming from abroad
For those traveling a long way, logistics and timing are themselves a burden. So we line up the precise exam, IOL consultation, surgery, and next-day check efficiently within a single visit. We're a one-minute walk from Sinnonhyeon Station and about 70 minutes from Incheon Airport, so getting around is simple. On-site Japanese, Traditional Chinese, and English interpreters mean you understand your measurements and the reason for each lens choice in your own language before deciding — and after you fly home, we keep helping in that same language.
How the surgery goes
- 1
1. Precise exam & biometry
Along with cataract severity, we measure eye length, corneal curvature, astigmatism axis, corneal endothelium, macula, and optic nerve. These numbers decide your IOL power and type.
- 2
2. Lens consultation & decision
Reviewing your results, we choose together among monofocal, multifocal, and toric — the IOL that fits your eye and your life. Pros and cons are explained fully, with an interpreter in your language.
- 3
3. Drop anesthesia & incision
Topical drops — no injection — numb the eye, then we make a 2–3mm micro-incision in the cornea. While you lie back, the eye is held steady and there's almost no sting.
- 4
4. Lens removal & IOL insertion
Ultrasound gently removes the clouded lens, then a folded IOL is inserted through the small incision and unfolded into place. The core step per eye is brief.
- 5
5. Finish & same-day check
The incision usually seals on its own without stitches. After a short rest we check the eye, explain protection and eye drops, and you head home with no hospital stay.
Recovery timeline
Vision is usually noticeably brighter that very day, though some haze, a gritty feeling, or watering is a normal reaction. Don't rub the eye, keep to the prescribed drops, and rest.
At the next-day check we review the incision, the IOL's position, and eye pressure. For most people this is when everyday life and light activity become possible again.
Vision settles over several days to a few weeks. Hold off on saunas, swimming, and straining exercise for a while, and with a multifocal lens your brain may need time to adapt to the new way of seeing.
The IOL itself never clouds again. If the membrane behind it hazes over later (after-cataract), a simple laser procedure clears it. Even after you fly home, our lifetime surgery guarantee means we stay by your side to the end, in your own language.

Frequently Asked Questions
Does cataract surgery hurt?
It's done under anesthetic drops, so without any injection the discomfort is greatly reduced. Most people feel bright light rather than a sting, and the eye is held steady during surgery so there's no worry about moving. Mild grittiness or watering afterward settles on its own. If you're anxious, feel free to ask us first on LINE or WhatsApp.
How long is recovery, and how many days should I stay in Korea?
Many patients can resume everyday life after the next-day check. Vision settles over a few days to a few weeks, and a multifocal lens may need a bit longer to adapt to. Counting both eyes and the next-day review, patients from abroad can usually finish in a short trip. The exact schedule depends on your eyes, so we'll tailor it for you in a free consultation.
Which is better — a monofocal or multifocal IOL?
It's hard to say one is simply better. A monofocal gives clean night vision and suits frequent night drivers; a multifocal scores high with people who want less reliance on glasses, though a minority notice night glare. The right answer comes from looking together at pupil size, corneal astigmatism, macular health, and your daily life. If your exam doesn't favor it, I'll honestly recommend a monofocal — so please consult with us freely.
Is cataract surgery safe? Are there side effects?
Cataract surgery is a long-established, common operation, but no surgery can claim a zero chance of infection or after-cataract. That's why I check the corneal endothelium, macula, and optic nerve in advance to gauge risk factors, and lower risk through sterile surgery and thorough follow-up. If an after-cataract forms, a simple laser clears it. I'll tell you honestly, after your exam, what the specific risks and realistic expectations are for your eyes.
Do I need surgery now, or can I wait?
Cataracts are usually not a time-sensitive emergency. If the clouding is mild and not greatly affecting daily life, we can watch it and decide on timing together. That said, there is a right window: when the haze clearly interferes with driving, work, or reading, or when waiting too long makes surgery more difficult. Whether 'now is the time' is judged most accurately by your measurements. We'll assess your current state objectively in a free consultation.
How much does it cost? Is it more expensive for foreigners?
Foreign patients pay exactly the same as Korean locals — 100% — with no tourist markup at all. The total does depend on your exam and the IOL you choose (monofocal / multifocal / toric), so the precise figure is given transparently in a free consultation after your exam. Rather than throwing out a vague number, I think it's more honest to tell you the cost alongside the plan that fits your eyes. Feel free to ask us on LINE or WhatsApp.
