Does ptosis surgery last? Recurrence, undercorrection and when a second operation is discussed

"Is ptosis surgery permanent?" is really three questions in one. Will the lid stay lifted? What if it ends up too low or too high? And if it does not hold, can it be done again? I cannot honestly answer the first with a yes or a no, and nobody who promises you one should be trusted. What I can do is show you what decides the answer, and what a good discussion of a second operation sounds like. If you have not yet read what the operation involves, start with what ptosis surgery actually fixes.

Is ptosis surgery permanent?

For many people the lift holds for a long time, but it cannot be promised for life, and how long it holds varies with the cause and the technique. Ptosis, the medical name for a drooping upper lid, is usually fixed by tightening or shortening the tissue that lifts the lid. That repairs the lid you have now. It does not stop the tissues around it from ageing, and it does not treat a nerve or muscle disease that may be causing the droop.

One recent report shows how much the technique matters. A review from a single centre, published in the journal Orbit in 2025, looked at 240 adults, 404 eyelids, followed for at least 3 months. It counted success in 90 per cent of lids after Müller muscle conjunctival resection, which shortens a small lifting muscle from inside the lid, and 79 per cent after external levator advancement, which tightens the main lifting tendon from the skin side. Success over 5 years was also better with the first technique. Please read those numbers as a description of one group of patients, not as a forecast for you. They vary with the cause and the technique, and a surgeon choosing between the two would be weighing your lid, not this table.

What decides whether the lid stays lifted?

The cause of the ptosis matters most, followed by how strong the lifting muscle is and a few things you can tell the surgeon about. Moorfields lists the causes: a defect in the levator muscle from birth, muscle or nerve weakness that can come with ageing or injury, long-term contact lens wear, trauma, or previous eye operations such as cataract surgery. Rarer causes include myasthenia gravis, a condition where muscles tire abnormally, and a third nerve palsy. The lid can also droop when weighed down by a cyst or swelling. Surgery cannot make a lid stay up for a disease that keeps pulling it down, which is why I would want the cause found first. I explain the different causes in why some eyelid ptosis is not ageing at all.

In the Orbit study, the factors linked with failure, in order of decreasing risk, were long-term use of prostaglandin eye drops, which are common glaucoma drops, long-term use of steroid eye drops, the surgical approach, a lower starting lid height, previous eye surgery, age, weaker lifting muscle and having blepharoplasty at the same time. These are associations in one group of patients, not rules. The practical message is simple: tell your surgeon about every eye drop you use, and about any previous eye surgery, before you decide.

What are undercorrection and overcorrection?

Undercorrection means the lid is still lower than planned. Overcorrection means it sits too high, and the eye may not close fully. Both are recognised outcomes of ptosis surgery, and neither is a verdict on the surgeon or on you. The lid height is set on a small structure, in millimetres, in a swollen lid, and the final height only shows once the swelling has gone.

That is why the first weeks are for waiting and watching, not judging. What follow-up checks, and how a lid that needs adjusting is handled, is in what ptosis surgery recovery actually involves, so I will not repeat it. If the eye will not close, or feels very dry, that is a reason to call sooner: lagophthalmos, when the eyelids do not close fully explains why it matters. If a lid is still clearly low or high after the swelling has settled, that is the point at which a second operation is discussed.

Can ptosis come back after surgery?

Yes, a lid can drop again, either because the repair loosens or because something new has started. The Orbit study is titled around exactly this, recurrence, and it found failure more likely with certain approaches and risk factors. The lifting tissue can stretch again over years, particularly if what stretched it in the first place, such as long-term contact lens wear, continues.

A drooping lid that returns can also be a different problem from the first one. The NHS lists a lid that droops suddenly, or that you cannot open, among the reasons to get urgent help, along with eye pain, changes in eyesight and a headache. A slowly returning droop is not urgent, but it does need assessing rather than assuming it is the old problem coming back. The action is a visit to an eye doctor, ideally the surgeon who knows your operation, or a second eye surgeon. If the droop is on the brow instead of the lid, that changes the operation, as I explain in droopy eyelid or droopy brow.

When is a second operation discussed, and is it a failure?

A second operation, called a revision, is discussed when the lid is clearly the wrong height or has dropped again after the swelling has fully settled, and it is a normal part of the conversation, not a failure. It is worth saying plainly, because people often feel they should not ask. Revision is a recognised part of the field.

A 2026 report in BMC Ophthalmology looked at 780 patients at one hospital who had one of the two operations. It found that 108, or 15 per cent, needed revision surgery, and it followed 28 who were re-operated with the other technique. The revision technique was chosen using a phenylephrine test: an eye drop that shows how the lid lifts, which helps predict which operation will suit that lid. The authors reported satisfactory results and lid symmetry in all 28. That is a small group at a single centre, so it is not a promise. But it does show what a careful plan looks like: test, choose, and match the second operation to the lid, not repeat the first.

If you are considering revision after an operation elsewhere, I would never want you to feel you must defend or criticise anyone. Bring your operation notes, and ask the questions in the next section. A second opinion before eyelid or orbital surgery is a sensible way to start.

Is ptosis surgery worth it, and what should I ask first?

It is worth it when the droop is genuinely getting in the way, and that is something you and a surgeon can test. Moorfields says a low upper lid can affect the top of your visual field and can cause difficulty keeping the lids open, eyestrain and eyebrow ache from the effort of lifting them. A visual field test, which maps the area you can see, is how a lid lifted for vision is assessed. How the medical-or-cosmetic question is approached is set out in is your eyelid surgery medical or cosmetic.

Before any ptosis operation, whether it is your first or a revision, these are the questions I would want you to ask me, when I begin consulting in early 2027, or any surgeon:

• What is causing my ptosis, and could it be something other than ageing?
• Which technique do you plan, and why that one for my lid?
• How long does this kind of repair typically hold, for the cause I have?
• What would make you suggest a second operation, and when would you decide?
• Do my eye drops, contact lenses or previous eye surgery change the plan?

The wider set of causes and the wider set of decisions are under eyelid conditions and what makes eyes look tired. A good answer to "how long will it last" starts with "it depends", and then tells you on what.
