In short. Ptosis correction is surgery for a drooping upper eyelid caused by a weak or stretched levator muscle, and it differs from removing hooded skin because it changes how far the eye can open. The operation tightens or shortens the muscle, with a measured target rather than the highest possible lid.
Key points
- Ptosis is a weak or stretched levator muscle, not simply hooded skin.
- It limits how far the eye can open; skin removal alone does not help.
- Surgery tightens or shortens the levator through a lid-crease incision.
- The target is a comfortable, natural lid, not the highest possible one.
- In children, a lid covering the pupil needs timely assessment.
What ptosis is
Ptosis is a droop of the upper eyelid caused by a weak or stretched muscle that lifts the lid, the levator. It can be present from birth, develop with age, or follow contact lens wear, injury, or earlier eyelid surgery. Unlike hooded skin, ptosis limits how far the eye can actually open.
Why is ptosis easy to miss?
Many people with ptosis are told they simply have small eyes or excess skin, because the drooping lid folds over a weak muscle. A careful examination measures how far the lid lifts and how well the muscle works, separating true ptosis from simple skin excess. Treating only the skin in someone with ptosis leaves the eye looking no more open.
Why it matters beyond appearance
In adults, significant ptosis can narrow the visual field, cause eyebrow aching from constant lifting, and create a persistently tired appearance. In children, a drooping lid that covers the pupil can interfere with normal visual development and needs timely assessment.
How the levator is tightened
The operation tightens or shortens the weak levator muscle through a fine incision in the lid crease, raising the lid to a more open and symmetric position. When the muscle works very poorly, an alternative procedure links the lid to the brow muscle, known as frontalis suspension. Surgery is usually performed under local anaesthesia with sedation.
| Finding or choice | What it involves | What it addresses | What to watch for |
|---|---|---|---|
| True ptosis | Measured lid lift and levator function | Separation from simple skin excess | Treating only the skin leaves the eye no more open |
| Levator tightening | A fine incision in the lid crease | A more open, symmetric lid | Under- or over-correction |
| Frontalis suspension | Links the lid to the brow muscle | A levator that works very poorly | The same lid-height and closure considerations |
| Target lid height | A deliberate, measured target | A lid that opens comfortably | Over-correction and dryness |
| A child with pupil coverage | Timely assessment | The risk to visual development | Delay |
What is the target lid height?
The aim is a lid that opens comfortably and looks natural, not the highest possible lid. Over-correction can prevent full eye closure and cause dryness, so a measured target is chosen deliberately.
Recovery
Swelling and bruising settle over one to two weeks. Because the lid has been repositioned, the eye may feel dry or tired at first, and lubricating drops are commonly used. Most people return to normal activity within two weeks, with the final lid height judged over several months.
Risks specific to ptosis surgery
Under- or over-correction, asymmetry between the two lids, difficulty fully closing the eye, usually temporary but occasionally persistent, and dry-eye symptoms are the main considerations. Small adjustments after full healing are sometimes discussed. Achieving exact symmetry is not always possible, particularly when the two muscles differ in strength.
When should a child be reviewed?
If a child's lid covers the pupil, or the head is tilted back to see, assessment should not be delayed, because of the risk to developing vision.

Frequently asked questions
How is ptosis different from simply having hooded skin?
Ptosis is a droop caused by a weak or stretched muscle that lifts the lid, so it limits how far the eye can actually open. Many people are told they simply have small eyes or excess skin. Measuring how far the lid lifts separates true ptosis from simple skin excess.
Why does ptosis matter in children?
A drooping lid that covers the pupil in a child can interfere with normal visual development, and a child who tilts the head back to see needs assessment without delay. In adults, significant ptosis can narrow the visual field and cause eyebrow aching from constant lifting.
What are the risks specific to ptosis surgery?
Under- or over-correction, asymmetry between the two lids, difficulty fully closing the eye, which is usually temporary but occasionally persistent, and dry-eye symptoms. Lubricating drops are commonly used at first. Exact symmetry is not always achievable, particularly when the two muscles differ in strength.
Risks & Limitations
- Dry eye, watering or a gritty sensation, which may be temporary or lasting.
- Difficulty closing the eye fully (lagophthalmos); if it persists it can expose the cornea and needs review.
- Asymmetry, an uneven crease, or under- and over-correction, which may require revision.
- Bruising and swelling that can take several weeks to settle.
- Visible or thickened scarring; scars are permanent but mature and fade over 6–12 months.
- Altered or reduced sensation around the lid, usually temporary but occasionally lasting.
When to Seek Care
- Any sudden change in vision, loss of vision, or double vision — seek emergency care immediately.
- Severe pain, or an eye that becomes tense, hard and swollen.
- Inability to close the eye, or new redness and pain in the eye itself.
- Spreading redness, warmth, pus or fever above 38 °C.
- Bleeding from the wound that does not stop with gentle pressure.
