Ptosis — the medical term for a drooping upper eyelid — sits on the boundary between functional and aesthetic ophthalmic surgery. When the eyelid drops far enough to encroach on the pupil, it restricts the upper visual field and can cause real symptoms: eye strain, brow ache, compensatory chin lift, and difficulty driving or reading.
What causes a drooping eyelid?
- Aponeurotic (age-related) ptosis — the most common cause. The levator muscle's tendon stretches or detaches over time.
- Congenital ptosis — present from birth, often due to a poorly developed levator muscle.
- Neurogenic ptosis — third cranial nerve palsy, Horner's syndrome, myasthenia gravis.
- Mechanical ptosis — caused by the sheer weight of excess upper-lid skin, a lid lesion or scarring.
- Traumatic ptosis — following injury or previous eye surgery.
How is ptosis assessed?
A proper oculoplastic assessment is essential before surgery. The consultant measures the height of the eyelid relative to the pupil (MRD1), the levator muscle function, the position of the upper-lid crease, and the symmetry between the two sides. Photographs are taken. Visual field testing is sometimes done to document the functional impairment, which is also important for insurance approval.
Surgical options
- Levator advancement / reinsertion — the standard adult procedure, performed under local anaesthetic, with the patient sitting up during surgery to fine-tune the height.
- Müller's muscle conjunctival resection (MMCR) — a posterior approach, ideal for mild ptosis with good phenylephrine response.
- Frontalis sling — used when levator function is very poor, particularly in congenital ptosis. The eyelid is suspended from the brow muscle.
- Often combined with upper-lid blepharoplasty if there is also excess skin.
Recovery
- Bruising and swelling for 1–2 weeks, peaking at day 2–3.
- Cold compresses, ointment to the wound and avoidance of heavy lifting for the first week.
- Stitches are usually removed at one week.
- Most patients return to office work after 7–10 days.
- Final cosmetic result settles over 2–3 months as residual swelling resolves and the lid crease defines.
Frequently Asked Questions
Is ptosis surgery covered by private medical insurance?
When ptosis is causing functional visual impairment — typically when the upper lid covers part of the pupil at rest — most UK private medical insurers will cover the procedure. Pre-authorisation requires documentation including measurements and often a visual field test.
Will I be awake during ptosis surgery?
Most adult ptosis surgery is performed under local anaesthetic with the patient awake, because the surgeon needs you to open and close your eyelid during the operation to set the height precisely. Sedation can be added if you are anxious.
How long do the results of ptosis surgery last?
Results are typically long-lasting — many decades. Recurrence is uncommon but possible, particularly in congenital cases. Aging changes in the face will of course continue, so a small revision in later years is occasionally needed.
