"Do I really need ptosis correction? Which is better, incisional or non-incisional?"
If you undergo surgery without understanding the difference between incisional and non-incisional ptosis correction, you may end up with a double eyelid line but still look sleepy, creating the so-called 'sausage eyes.'
To start with the conclusion, double eyelid surgery and ptosis correction are completely different procedures.
If double eyelid surgery creates the 'line,' ptosis correction adjusts the 'strength of opening the eyes.'
So today, I’ll organize the differences between double eyelid surgery and ptosis correction, and help you figure out whether incisional or non-incisional is right for your eyes.

Double eyelid surgery vs. ptosis correction: what’s the difference?
Let me explain it simply.
Double eyelid surgery is a procedure that folds the eyelid skin to create a crease.
Ptosis correction is a procedure that strengthens the muscle that opens the eyes so that more of the black part of the eye is visible.
Take a look in the mirror. When you open your eyes, are you unconsciously lifting your forehead or eyebrows?
If the black part of your eye is covered a lot by the eyelid and you look sleepy or drowsy,
it is likely not just sagging skin, but ptosis.
What happens if you only get double eyelid surgery for eyes like this?
The sleepy feeling remains, but only the line is created, which can actually make the result look more awkward.
That is why ptosis correction, which adjusts the muscle that opens the eyes, is needed.
Incisional vs. non-incisional ptosis correction, a side-by-side comparison
| Category | Non-incisional ptosis correction | Incisional ptosis correction |
|---|
| Surgical method | Fixing the Mueller muscle through tiny openings | Direct adjustment of the levator palpebrae superioris muscle after incision |
| Suitable eyes | Mild ptosis, thin eyelids | Moderate to severe ptosis, thick eyelids |
| Correction effect | Natural improvement | Clear and definite change |
| Recovery period | About 3–5 days (fast) | About 7–14 days |
| Scarring | Almost none | Hidden within the double eyelid line |
| Durability | May loosen | Semi-permanent retention |
Natural and subtle, non-incisional ptosis correction
This method is often performed together with double eyelid surgery, commonly called 'natural adhesion.'
Without making an incision in the skin, the procedure uses tiny openings to pull and tie the Mueller muscle inside the eyelid with sutures.
Recommended for people who:
· Do not have severely weak eye-opening strength (mild ptosis)
· Have thin eyelid skin and little fat
· Are concerned about scars and want a quick recovery
Because there is no incision, there is less swelling or bruising, and recovery is faster, so many people who prefer natural results choose this option.

Clear and defined, incisional ptosis correction
"Can’t I just do the non-incisional method?" I understand the preference, but depending on the condition of the eyes, we may advise against it.
If the eyelids are thick, there is a lot of fat, or the eye-opening strength is very weak, it is difficult to correct these cases with the non-incisional method alone.
Forcing a non-incisional approach may cause it to loosen quickly or have only minimal effect.
Incisional ptosis correction is a procedure in which the skin is incised so the levator palpebrae superioris muscle can be directly seen and adjusted.
It can remove sagging skin and excess fat at the same time, and because the muscle is adjusted directly, the correction effect is clear.
Recovery takes a little longer than with the non-incisional method, but if you want a defined eye shape that won’t loosen over time, the incisional method may be the right answer.
Common points of confusion during consultations
Many people think, "If I just get double eyelid surgery, won’t my eyes look bigger?"
But if the root cause of small-looking eyes is ptosis, double eyelid surgery alone won’t solve it.
If you recommend only double eyelid surgery without ptosis correction for such a person, it may lead to dissatisfaction with the result.
Before surgery, we recommend a clinic that precisely measures the strength of eye opening and accurately guides you to the more suitable method between incisional and non-incisional approaches.
Frequently Asked Questions (FAQ)
Q. Will ptosis correction make it hard to close the eyes?
The key is to adjust the amount properly so that overcorrection does not occur.
Right after surgery, swelling may make it feel harder to close the eyes, but as the swelling goes down, they will close naturally.
Q. Can ptosis correction be done without double eyelid surgery?
Yes, it can.
You can create a very thin double eyelid line like a hidden crease, or perform only the correction without making it visible, so that only the eye size increases.
This is a method often preferred by men.
Q. If I had the non-incisional method first, can I later have revision surgery with the incisional method?
Yes, that is possible.
If you had the non-incisional method and later the skin sags or the fixation becomes weak, you can have revision surgery with the incisional method then.
Q. Is the scar from incisional ptosis correction noticeable?
Because the incision is hidden within the double eyelid line, it becomes barely visible over time.
It usually looks natural after 2–3 months.
In summary,
The most important thing in ptosis correction is understanding the condition of your own eyes.
If the skin is thin and there is no sagging → non-incisional ptosis correction
If the skin is thick and a definite correction is needed → incisional ptosis correction
It is not a matter of "non-incisional is better" or "incisional is better" in every case,
but rather of first receiving an accurate diagnosis of the amount of fat in your eyelids, skin thickness, and muscle strength.
If you find yourself using your forehead every time you look in the mirror, we recommend visiting the clinic and getting your eye-opening strength checked.
