Entropion Surgery: When You Need It, What Happens and How Recovery Goes
Entropion surgery is an eyelid operation that turns an inward-rolling eyelid edge back to its normal position, so the lashes stop rubbing against the eye. It is usually advised when entropion causes constant irritation, keeps coming back, or starts to scratch the cornea, the clear window at the front of the eye.

Imagine a soft brush sweeping across your eye every time you blink, thousands of times a day. Not exactly a spa treatment. That is daily life with entropion.
What is entropion?
Entropion means the eyelid edge rolls inward, most often in the lower lid. Lashes and skin rub on the eye, causing a gritty feeling, watering, redness, light sensitivity and sometimes mucus or crusting. Our article on why only one eye is watering covers other causes of watering.
Entropion is not quite the same as ingrown eyelashes (trichiasis), where the lid sits normally but some lashes grow toward the eye. Both can scratch the cornea and are treated differently, so an examination matters.
What causes entropion?
Age-related laxity: the tendons and muscles that hold the lower lid stretch over time, so the edge tips inward. This is the most common type.
Scarring: scars on the conjunctiva, the thin lining inside the lid, from chronic inflammation, infection, chemical injury, trauma or surgery can pull the lid edge inward.
Spasm: irritation can make the muscle around the eye squeeze hard enough to roll the lid in for a while.
Epiblepharon in children: an extra fold of skin and muscle below the lashes pushes the lower lashes toward the eye. It is common in East Asian children and often improves as the face grows.
When is entropion surgery needed?
Lubricating drops or gel ease the friction, and a doctor may suggest taping the lower lid or a protective contact lens for a while. These steps buy comfort but do not correct the lid position. Age-related and scarring entropion rarely go away on their own, so surgery is usually considered when symptoms persist or the cornea is at risk.
What happens during entropion surgery?
Entropion surgery is done by an eye surgeon, often an oculoplastic surgeon who focuses on eyelids. The aim is to tighten the loose tendon and muscles and turn the lid edge back to its normal position. The technique depends on the cause, and your surgeon will explain the plan, anaesthesia and aftercare that suit you.
Entropion surgery recovery
Expect some bruising and swelling at first. These usually settle over about 7–14 days, and stitches that need removing are typically taken out at around 7–14 days. Follow your surgeon's instructions on drops, cleaning and activity, and see how to reduce swelling after eyelid surgery for general tips.
When should you see an eye doctor urgently?
eye pain that is severe or getting worse
blurred vision
strong sensitivity to light
a white spot on the clear front of the eye
increasing redness or pus-like discharge
These can be signs of a corneal ulcer or infection. After surgery, contact your surgeon promptly if pain, bleeding or swelling suddenly increases, or vision changes.
Frequently asked questions
Can entropion go away on its own?
Age-related and scarring entropion usually do not resolve by themselves. Entropion caused by spasm can settle once the irritation is treated, and inward-turning lower lashes in young children often improve as they grow.
How long does entropion surgery recovery take?
Bruising and swelling usually settle over about 7–14 days, and stitches that need removing are typically taken out at around 7–14 days. Your own timeline depends on the technique and how you heal.
Are ingrown eyelashes the same as entropion?
Not exactly. In entropion the whole eyelid edge turns inward. With ingrown eyelashes (trichiasis), the lid sits normally but some lashes grow toward the eye. An eye examination tells them apart.

If your eye feels gritty and watery day after day, an examination can show whether the lid, the lashes or something else is to blame.
