You've seen the "cat eye" transformations all over TikTok and wondered: is this eyeliner trickery, or actual surgery?
Canthoplasty is real surgery with real risks — here's what US patients are actually asking before they book a Seoul consult.
Canthoplasty Isn't Double Eyelid Surgery — Here's the Actual Difference
Canthoplasty reshapes the outer corner for an upward cat-eye slant, unlike double eyelid (crease) or lower bleph (fat) .
Epicanthoplasty removes the inner fold, paired with canthoplasty for a wider eye .
| Item | Canthoplasty | Canthopexy |
|---|---|---|
| Price | $3-7k | $1.5-3.5k |
| Downtime | 10-14d | 5-7d |
| Longevity | Permanent | 2-5yr |
| Cut | Yes | No |
| Scar | Mod | Low |
Dr. Steinsapir warns fold removal risks a visible scar — ask which technique is planned before booking.
The Recovery Timeline Nobody Posts on Instagram
Swelling and bruising peak, then fade over one to two weeks — no overnight glow-up here .
Peak swelling, bruising.
Sutures out, redness fades.
Back at your desk again.
Eye shape settles in.
The surgery runs 30-60 minutes solo, under two hours combined .
Results are generally permanent, though aging can shift the corner over time.
Over-Correction and Revision: What RealSelf Threads Are Actually Saying
Scroll through RealSelf and you'll notice results hinge more on clinic than country. One reviewer at AB Plastic Surgery in Seoul called it "smooth progress, good result, no complaints" .
Then there's the other side. A patient at Mine Plastic Surgery didn't sugarcoat it: "NOT A PENNY... they even made my eyes worse" . Same city, opposite outcome — proof your specific surgeon matters more than the country stamp.
⚠️ Documented risks include asymmetry, ectropion (outward-turning lower lid), scarring, and chronic dry eye, with one study finding minor side effects in roughly 7-10% of patients .
Reversing a canthoplasty is genuinely tough and may never fully restore your original eye shape. Board-certified oculoplastic surgeon Dr. Barry Eppley urges patients to understand technique differences before booking .
Pricing Transparency: Seoul Quotes vs. US Oculoplastic Surgeons
Let's talk numbers. Seoul eye-enlargement packages — canthoplasty plus epicanthoplasty or ptosis correction — run about $2,000–$5,000 at clinics like Sinsa L Plastic Surgery under Dr. Lee Young-geun and UE Plastic Surgery .
Cosmetic canthoplasty typically isn't covered by US insurance unless it corrects a genuine eyelid malposition . Factor in flights, one to two weeks of Seoul lodging, and follow-up visit logistics before you compare sticker prices.
Whichever city you choose, vet your surgeon's board certification and actual canthoplasty case volume before booking .
Not really — results are meant to be permanent, and undoing them rarely restores your original eye shape.
Canthoplasty reshapes the outer corner for a cat-eye lift; epicanthoplasty removes the inner fold to widen eyes.
Basically never — it's classified as cosmetic, though medically necessary eyelid repairs may sometimes qualify.
Swelling fades in 1-2 weeks, but final results take up to 3 months; most fly home after 7-10 days.
