Pterygium Surgery in Korea: Cost, Candidacy & Recovery
What is a pterygium and when does it need surgery?
A pterygium is a wedge-shaped, fleshy growth of the conjunctiva that spreads from the white of the eye onto the cornea, most often on the nose side. It is linked to ultraviolet light, wind and dust, and is common in people who spend long hours outdoors.
Small pterygia are often just watched and treated with lubricating drops. Surgery is considered when the growth threatens the visual axis, causes astigmatism that blurs vision, makes contact lens wear impossible, is persistently inflamed, or is a cosmetic concern. Because it can affect corneal shape, a pterygium can also interfere with measurements for LASIK or cataract surgery, and some surgeons remove it first and re-measure later.
Which surgical technique is used?
The growth is excised under local anaesthetic, and the main difference between techniques is what covers the bare area afterwards, which largely decides the recurrence risk.
| Technique | How it works | Evidence (AAO technology assessment) |
|---|---|---|
| Bare sclera excision | Growth removed; area left to heal | Significantly higher recurrence than adjuvant methods |
| Conjunctival or limbal autograft | Healthy tissue from your own eye covers the area | Lower recurrence; better than amniotic membrane |
| Amniotic membrane graft | Donor membrane covers the area | Less effective than autograft for recurrence |
| Mitomycin C (MMC) adjuvant | Anti-scarring drug applied during surgery | Lowers recurrence; can cause scleral thinning at higher doses |
| Autograft plus MMC | Both combined | Further reduces recurrence vs either alone |
The American Academy of Ophthalmology's assessment (Ophthalmology, 2013) concluded there was not enough evidence to name one adjuvant as best; the choice depends on whether the pterygium is primary or recurrent, your age and surgeon preference. Grafts are held with sutures or tissue glue.
How much does pterygium surgery cost in Korea?
Prices depend on technique, whether the pterygium is recurrent, and hospital type. A 2026 Korean consumer guide put total costs at about ₩400,000–₩2.2 million (approximately $290–$1,630 at ₩1,350–₩1,400 per dollar), with university and specialist hospitals at the higher end and non-covered extras such as amniotic membrane adding cost. That guide also notes that the insured patient's share for basic surgery is much lower; visitors without Korean National Health Insurance pay the full uninsured fee, and repeat surgery for a recurrence is more complex and more expensive. This guide is not an official source, so treat it as indicative and ask for a written, itemised estimate per eye before booking.
What happens on the day of surgery?
Pterygium surgery is usually a day procedure lasting about 30–45 minutes. The eye is numbed with drops and a local anaesthetic injection near the eye, and you stay awake. The surgeon peels the growth off the cornea, removes the abnormal tissue from the white of the eye, and smooths the corneal surface. If an autograft is used, a thin piece of healthy conjunctiva is taken from under your upper lid and secured over the bare area with fine sutures or fibrin glue. Mitomycin C may be applied briefly in recurrent cases. You go home with a patch or shield, antibiotic and steroid drops, and instructions to avoid rubbing the eye.
Ask in advance whether the clinic uses sutures or glue, because sutures can feel scratchy for a week or two and may need removal at a follow-up. Also ask how long steroid drops continue, since these are tapered over weeks and play an important part in reducing recurrence.
Should I have pterygium surgery during a trip to Seoul?
Only if you can stay long enough for follow-up. The first post-operative check is usually the next day, and sutures or graft position are reviewed again within one to two weeks. If you plan a short visit, it may be better to have the diagnosis and an opinion in Seoul and schedule surgery where you can be followed up. People living in Korea or staying several weeks can reasonably have it done here. Use our English-speaking vision clinics guide to find a clinic, and the private clinic vs university hospital guide if your pterygium has recurred, since recurrent cases are more complex.
Who is a good candidate?
- Growth approaching the pupil or causing astigmatism and blur
- Chronic redness or irritation not controlled by drops
- Contact lens intolerance due to the growth
- Planned refractive or cataract surgery needing accurate corneal measurements
Any atypical growth should be checked to rule out other surface lesions before surgery.
What is recovery like?
| Time | What to expect |
|---|---|
| Days 1–7 | Grittiness, redness, watering; antibiotic and steroid drops |
| Weeks 1–2 | Desk work and reading usually resume; sutures may be removed |
| Weeks 2–4 | Redness fades; most people back to normal life |
| About 1 month | Sport and swimming usually allowed |
| First year | Wear UV-blocking sunglasses outdoors; attend recurrence checks |
If you are flying home, use lubricating drops on the plane and carry your discharge notes; see getting medical records in English and follow-up care after returning home.
What are the risks?
The main risk is recurrence, which can be more aggressive than the original growth. Other risks include graft swelling or displacement, infection, scarring, temporary double vision, and, with mitomycin C, scleral thinning or delayed healing. This is general information; have a full exam and follow an ophthalmologist's advice.

FAQ
Frequently asked questions
Can a pterygium go away without surgery?
No, but small ones often stay stable and only need lubricating drops and UV protection. Surgery is for growths that affect vision, comfort or appearance.
How likely is a pterygium to come back?
Recurrence is lower with a conjunctival autograft, mitomycin C, or both, than with bare-sclera removal. UV protection after surgery also helps.
How much is pterygium surgery in Korea for a foreigner?
A 2026 Korean consumer guide cites about ₩400,000–₩2.2M depending on method and hospital. Visitors without Korean insurance pay the full fee, so request a written estimate.
How long is recovery?
Most people return to daily activities in 2–4 weeks; sport and swimming usually wait about a month.
Can I have LASIK if I have a pterygium?
A pterygium can distort corneal measurements. Many surgeons remove it first and re-measure before planning laser surgery.
