Eyelid ptosis surgery raises an upper lid that droops because its lifting muscle, the levator, has stretched, detached or never developed fully. The surgeon tightens or reattaches the muscle through a crease incision or from inside the lid, or links the lid to the forehead muscle. It is usually done as day surgery, often under local anaesthesia.
This guide is part of our eye lift overview. Ptosis repair is different from a cosmetic eye lift, though the two are often combined.
What is ptosis?
Ptosis is a low-sitting upper eyelid margin, most often from a stretched lifting muscle in adults or an underdeveloped muscle in children.
An NHS hospital leaflet from Alder Hey Children’s Hospital lists the main causes: a weak lifting muscle, nerve problems, the way the muscle developed, or the muscle separating from its attachment after injury, long-term contact lens wear or previous eye surgery. People often raise their brows or tip their chin up to see, which can cause forehead fatigue or neck ache.
Ptosis isn’t the same as excess eyelid skin. The American Society of Plastic Surgeons (ASPS, US) explains that drooping caused by a stretched eyelid muscle needs a different operation from standard eyelid surgery. Hooding from a low brow is another separate problem; see hooded eyes.
In children, a lid that covers the pupil can affect how vision develops, so early assessment matters.
Eyelid ptosis surgery types
The type of eyelid ptosis surgery depends on how strong the lifting muscle is and how far the lid droops.
| Technique | When it’s used | Approach |
|---|---|---|
| Levator advancement or resection | Muscle has some strength; most adult age-related ptosis | Through the eyelid crease; tendon tightened or reattached |
| Müller’s muscle resection | Small droop, about 1 to 2 mm | From inside the lid; no skin incision |
| Brow (frontalis) suspension | Very little lid movement, often congenital | Lid linked to the forehead muscle through small incisions |
Results can be good. A 2018 study in Plastic and Reconstructive Surgery Global Open followed 303 eyes in 192 adults (average age 65) with severe ptosis repaired by a closed posterior levator technique. Average lid height improved by about 3 mm, contour was rated satisfactory in 98.3% of eyes and only 1.8% needed revision. It was a single-surgeon study, so results may differ elsewhere.
Ptosis repair is often combined with removal of extra skin; our upper eye lift guide covers that part. In my practice, I adjust lid height with the patient sitting up during surgery where possible, because lid position changes when you lie down.
Recovery
Bruising usually settles within two weeks, swelling within about three months, and lid height and shape can change until then.
The Alder Hey leaflet describes recovery in children, and the pattern is similar in adults:
- Bruising can take up to two weeks to settle.
- Swelling is much reduced by two weeks but can take up to three months to resolve.
- Lid height and shape may change over the first three months, so the final result is judged after that.
- Cool compresses help discomfort; avoid rubbing the eyes.
Common risks include under-correction needing further surgery, uneven height or contour and scarring. Over-correction can stop the eye closing fully, causing dryness and irritation of the cornea. Bleeding behind the eye is rare but an emergency, signalled by pain, vision loss or a bulging eye.
Is there a non-surgical option?
In 2020 the US Food and Drug Administration (FDA) approved oxymetazoline 0.1% eye drops for acquired ptosis in adults, according to Healio. Used once daily, they act on Müller’s muscle to raise the lid slightly. Side effects in 1% to 5% of users included eye redness, dry eye, blurred vision and headache. The effect lasts only while you keep using them. See our non-surgical eye lift guide for other options.
Insurance
Insurers may cover ptosis repair when tests show the lid blocks your vision; surgery purely for appearance isn’t covered.
US Medicare, for example, looks for a minimum 12-degree or 30% loss of upper visual field, tested with the lid at rest and again taped up, plus frontal photos. Prior authorization is required, and surgery done only for appearance isn’t covered. Private insurers set their own rules, so check before booking. ASPS adds that most health insurance doesn’t cover cosmetic eyelid surgery.
Frequently Asked Questions
FAQ
Answers on ptosis surgery anaesthesia, how long results last, whether ptosis comes back and children’s ptosis treatment.
Is ptosis surgery done awake?
Adult ptosis repair is often done under local anaesthesia, sometimes with sedation, so you can open your eyes when asked. That helps the surgeon set the lid height. Children usually have general anaesthesia. Most people go home the same day.
Can ptosis come back after surgery?
It can. Under-correction is one of the more common issues and may need further surgery. Aging can also slowly lower the lid again over many years. In one 2018 adult series, the revision rate was 1.8%, though rates vary by technique and surgeon.
How long until my eyelids look even?
Swelling is much reduced by two weeks, but lid height and shape can keep changing for up to three months. Most surgeons judge the final result after that point, and small adjustments, if needed, are planned once healing is complete.
Should a child with ptosis have surgery?
It depends on whether the lid blocks the pupil. The Alder Hey leaflet says surgery is strongly advised if it does in a child under seven, because of the risk of lazy eye. If the pupil is clear, the decision can often wait.
If you’d like your lid height and brow position assessed, you can book a consultation with Metropole Clinic by ABmedi. For cosmetic eyelid options and costs, return to the eye lift hub.
