Ectropion is when the lower eyelid turns outward, away from the eye; entropion is when it turns inward, so the lashes rub the eyeball. Both are usually caused by age-related eyelid laxity and can lead to watering, irritation and, if untreated, corneal damage. Both are highly treatable — most often with a short, day-case surgery under local anaesthetic. At Eyes Defined in London, consultant oculoplastic surgeon Dr. Ahmad Aziz corrects both conditions to relieve symptoms and protect your sight.
If your eyelid no longer sits neatly against your eye — sagging outward, or curling inward so the lashes scratch — you are not imagining it, and you are not alone. These two eyelid problems, ectropion and entropion, are among the most common eyelid conditions seen in older adults. They can be uncomfortable, embarrassing and, left untreated, genuinely harmful to your vision. The reassuring news: both are well understood and highly treatable. This guide explains what each condition is, how to tell them apart, why prompt treatment matters, and how they are corrected at our London oculoplastic clinic.
1. Ectropion vs. Entropion: What’s the Difference?
The two conditions are mirror images of the same underlying problem — an eyelid that has lost its normal tension and position. The direction in which the lid turns is what sets them apart.
Ectropion — when the eyelid turns outward
In ectropion, the lower eyelid droops and rolls away from the eye, leaving the inner pink surface exposed. Because the lid no longer hugs the eyeball, tears can’t drain properly and the surface dries out — which, frustratingly, often makes the eye water more, not less.
Entropion — when the eyelid turns inward
In entropion, the eyelid rolls inward, pressing the eyelashes and skin against the surface of the eye. Every blink drags the lashes across the cornea, causing a constant scratchy, gritty sensation. This is not just uncomfortable — the friction can damage the delicate front surface of the eye over time.
Understanding which way your lid is turning is the first step toward the right treatment.
2. Symptoms: How to Know Which One You Have
Both conditions share some overlapping symptoms — watering and irritation are common to each — but the pattern of discomfort differs.
Common signs of ectropion
With the lid turned outward, you may notice excessive watering and tears spilling over the cheek, a sore or red exposed inner lid, dryness or a burning sensation, crusting in the morning, and increased sensitivity. Because the eye is left exposed, many people feel their eye is permanently irritated or “raw.”
Common signs of entropion
With the lid turned inward, the hallmark is the feeling of something constantly scratching the eye — a foreign-body or “eyelash in the eye” sensation that never goes away. You may also experience redness, watering, light sensitivity, and a reflex urge to rub the eye, which only makes matters worse.
⚠️ Warning signs that need prompt specialist attention
Seek a specialist assessment promptly if you develop persistent pain, blurred vision, increasing redness, or a sense that your sight is affected. These can signal that the cornea — the clear window at the front of the eye — is becoming damaged, and timely treatment protects your vision.

3. What Causes Eyelids to Turn Out or In?
Eyelids rely on muscles, tendons and skin to hold them firmly in place. When any of these weaken, the lid can lose its position.
Age-related changes (the most common cause)
The most frequent cause of both ectropion and entropion is simply ageing. Over time the small tendons that anchor the eyelid stretch and the supporting muscles slacken — this is known as involutional change. It’s the reason both conditions are far more common after the age of 60.
Scarring, skin conditions & previous surgery
Sometimes scarring pulls the eyelid out of shape — called cicatricial change. This can follow burns, chronic skin inflammation, certain skin conditions, trauma, or previous eyelid surgery that has tightened the skin in the wrong direction.
Nerve weakness and congenital cases
Weakness of the facial nerve — for example after Bell’s palsy or a stroke — can leave the lid unable to hold its position, a paralytic cause more often linked to ectropion. Rarely, children are born with an eyelid that turns the wrong way (congenital), which requires specialist paediatric oculoplastic care.
Identifying the underlying cause matters, because it directly shapes which surgical technique gives the best, longest-lasting result.
4. Why Treatment Matters: Protecting Your Sight
It’s tempting to dismiss a turned eyelid as a cosmetic nuisance. In reality, both conditions can threaten the health of the eye itself.
How entropion can risk corneal damage
When lashes continuously rub the cornea — a condition called trichiasis when individual lashes misdirect — they can scratch and eventually scar the surface. Repeated abrasion raises the risk of infection and, in severe cases, lasting damage to vision. This is why entropion should never be left to “settle on its own.”
How ectropion causes exposure and chronic watering
With ectropion, the exposed eye surface dries out, a problem known as exposure keratopathy. Chronic dryness, watering and recurrent irritation not only feel miserable but can also compromise the cornea if neglected. Treating the malposition restores normal tear drainage and protects the eye.
5. Treatment Options at Our London Clinic
The right treatment depends on the severity and the underlying cause. At Eyes Defined, treatment is led by a consultant oculoplastic surgeon, so your plan is tailored to your specific eyelid — not a one-size-fits-all approach.
Non-surgical and temporary measures
In mild cases, or while you await surgery, lubricating drops and ointments soothe the surface and protect the cornea. Taping the lid or, in selected paralytic cases, carefully placed Botox can offer temporary relief. These measures manage symptoms but do not correct the underlying laxity — surgery remains the definitive solution for most patients.
Surgical correction — the day-case solution
For lasting results, the eyelid is surgically tightened and repositioned. A common, highly effective technique is the lateral tarsal strip, which tightens the lid and restores its natural contact with the eye. The exact method is chosen to match your cause — whether age-related laxity, scarring or nerve weakness.
What the procedure involves
Reassuringly, eyelid-correction surgery is usually a day-case procedure performed under local anaesthetic. It typically takes around 30 to 45 minutes, you remain awake and comfortable, and you go home the same day. There’s no overnight hospital stay and no general anaesthetic for most patients.

6. Recovery & What to Expect After Surgery
Recovery from eyelid surgery is generally quick and well tolerated.
The first week
Expect some swelling and bruising around the eye, which settles over the first one to two weeks. You may have fine stitches that are removed or dissolve within a couple of weeks, and you’ll be given lubricating drops and simple aftercare instructions. Most people manage with over-the-counter pain relief.
Returning to normal and long-term results
Many patients return to light daily activities within a few days, with the eye feeling markedly more comfortable as the irritation resolves. Once healed, the lid sits correctly against the eye again — relieving the watering, scratching and soreness, and protecting your long-term eye health. Results are typically durable and long-lasting.

Frequently Asked Questions
No. The surgery is performed under local anaesthetic, so the eyelid is fully numbed and you stay comfortable throughout. Most patients feel only mild soreness afterward, easily managed with simple pain relief.
Eyelid correction is usually a quick day-case procedure lasting around 30 to 45 minutes. You go home the same day, with no overnight hospital stay and no general anaesthetic for most patients.
No, neither condition resolves on its own because the underlying eyelid laxity is structural. Drops and ointments may ease symptoms temporarily, but surgical correction is the only lasting solution for most people.
If your lower eyelid sags outward and your eye feels exposed and watery, that suggests ectropion. If your eyelid rolls inward and your lashes feel like they're constantly scratching the eye, that points to entropion. A specialist can confirm the diagnosis in one examination.
Yes. At Eyes Defined in Marylebone, consultant oculoplastic surgeon Dr. Ahmad Aziz offers prompt private correction of both ectropion and entropion, avoiding long NHS waiting lists. You can book by calling +44 20 7965 7484.
Most swelling and bruising settles within one to two weeks, and many people return to light daily activities within a few days. The eye usually feels noticeably more comfortable soon after the lid is repositioned.
It can. Untreated entropion lets lashes scratch the cornea, while untreated ectropion leaves the eye exposed and dry — both of which can harm the eye's surface over time. Prompt treatment protects your vision.
The most common cause is ageing, which stretches and weakens the tendons that hold the eyelid in place. Scarring, nerve weakness, and previous surgery are other possible causes.
In selected cases — particularly when nerve weakness is involved — carefully placed Botox can offer temporary relief. It does not correct the underlying laxity, so surgery remains the definitive treatment for most patients.
When the lid turns outward, tears can no longer drain through their normal channel, so they pool and overflow onto the cheek. Correcting the eyelid position restores proper tear drainage.
An oculoplastic surgeon — an ophthalmologist who subspecialises in the eyelids and tissues around the eye — is the ideal specialist for these conditions. Dr. Ahmad Aziz at Eyes Defined is a consultant oculoplastic surgeon in London.
It can be available on the NHS when there is a clear medical need, though waiting times for assessment and surgery are often long. Private treatment in London offers faster access and your choice of consultant.
