True involutional entropion
Lashes rub the cornea
Last reviewed: 2026-10-06 · 潘家健醫生
Key points
True entropion is an abnormal lid-margin position with lashes rubbing the cornea; involutional entropion is common in older adults.
Unlike epiblepharon, the lid margin itself is malpositioned.
Severe pain, sudden vision drop or a white cornea needs prompt ophthalmology care.
Surgery is an examination decision — no booking or clinic comparison here.
What it is
Ageing lid tissues let the margin turn in so lashes rub the cornea. It is not the same as childhood epiblepharon.
What a doctor may discuss
Tape or lubricant as a stopgap
Surgery to tighten and re-position the lid — type is individual

This is general medical information, not a diagnosis, and cannot replace an in-person consultation with a registered ophthalmologist, refraction, or a dilated fundus exam. It is not advice to use any medicine or undergo any procedure. Medicines (including off-label use), laser or surgery must be decided by a registered doctor after examination, according to indications and Hong Kong registration. Figures from the literature are published averages, not any clinic’s results. This site does not book, prescribe or refer. Do not change treatment on your own.
