Gangnam · Seoul · South Korea

Wake up to a life without glasses.

Q: What should I do before my visit?

Stop wearing soft contact lenses for at least 5–7 days before your exam (2–3 weeks for hard/RGP lenses) so your cornea returns to its natural shape for accurate measurement. Bring your glasses and any prescription records, arrange a companion or transport for surgery day, and avoid eye makeup on exam day.

Q: What if my vision is still blurry after surgery?

As the cornea heals, vision recovers gradually and temporary haziness is completely normal. We recommend avoiding screens where possible and diligently using your prescribed eye drops and artificial tears for the first 1–3 months. If you feel a foreign-body sensation or pain, visit us immediately — or see a local ophthalmologist and then contact us.

EYEONCE is a Gangnam vision-correction specialist trusted by patients from around the world. SMILE PRO, SMILE LASIK, ICL and premium cataract care — with English-speaking staff and same-day surgery.
