Mokdong Plastic Surgery Recommendation: Eyelid Surgery

Most people who are considering eyelid surgery

often ask,

“Why does the line look so different?” ,

“Why do my eyes feel different in every photo?”

At first glance, it may seem like a simple procedure that just creates a line,

but in reality, a 0.1 mm difference is an area that can change the overall impression.

This is also the point that is emphasized most often during consultations.

Today, I’ll calmly explain why the 0.1 mm difference in eyelid surgery is so important,

and on what basis it is decided.

  1. The key to eyelid surgery is not the ‘line height’

but the ‘balance between muscle and skin’

  1. Why a 0.1 mm difference appears: because the eyelid is the face’s most ‘sensitive structure’

  2. Why the impression of the eyes changes even when the line height is the same

  3. More important than the surgical method is

‘how the eye opens’

  1. The way to reduce left-right differences in eyelid surgery,

‘measurement’ and ‘movement analysis’

  3. The key to eyelid surgery is not the ‘line height’ but the ‘balance between muscle and skin’

People often pay attention only to the height of the double eyelid line,

but in reality, the impression of the eyes changes as the following factors differ subtly.

Factors that create a 0.1 mm difference

• Thickness of the eyelid skin

• Amount of fat

• Strength of the levator palpebrae superioris muscle (the muscle that opens the eyes)

Fascial position

• The subtle depth of the eyelid fold

• Degree of left-right asymmetry

• Angle of the eyelashes

These values are not simply changed “dramatically”

but are fine-tuned little by little—that is what eyelid surgery is.

So even if it looks like a very small difference to the patient,

medically it can be a factor that creates a major change in impression.

  1. Why a 0.1 mm difference appears,

because the eyelid is the most ‘sensitive structure’ on the face

Image to help explain the skin layers

The eyelid has thin skin, and the muscle and fat layers are arranged thinly,

so even small changes can greatly alter the impression.

  1. The overlapping layer of skin and muscle is thin

→ Even if the fold position changes just a little, the line can look different.

  1. Eyes with more fat have difficulty maintaining the line

→ A 0.1 mm difference can determine how well the line is fixed.

  1. If the muscle strength is weak, the line collapses even if it is made high

→ In practice, ‘muscle reinforcement’ is often more important than the line itself.

  1. There is a subtle but consistent difference between the left and right eyes

→ Accurate measurement before surgery is necessary.

Eyelid surgery is not something that is decided by simply entering a mathematically exact value,

but rather by looking at the eye-opening pattern, eye movement, and balance with the eye shape while making fine adjustments.

  1. Why the impression of the eyes changes even when the line height is the same

Mokdong Plastic Surgery Recommendation: Eyelid Surgery

A lot of people ask, “Why do the two eye lines look the same but feel different?”

The reason is that the differences in the factors below have a much greater effect than the line itself.

  1. When the strength of the eye-opening muscles is different

If one eye opens less, the line looks deeper and more pronounced.

  1. When the amount of fat and muscle differs between left and right

Even at the same height, the lines are maintained differently.

  1. Skin laxity

The side with thicker skin makes the line look deeper,

and the thinner side looks like a natural inner double eyelid.

  1. Direction of the eyelashes

If the outer side is drooping or lifted,

the angle at which the line flows looks different.

In this way, the eye is not just a simple curve, but a structure determined by a combination of small elements.

  1. More important than the surgical method is ‘how the eye opens’

Mokdong Plastic Surgery Recommendation: Eyelid Surgery

Many people considering eyelid surgery ask,

“Is the buried suture method better? Or is the incision method better?”

but what really matters is not the method, but

the structure of the muscles that open the eyes.

  1. In these cases, the buried suture or non-incision method is more natural

• Thin skin

• Almost no fat

• Good line maintenance

• Need for a quick recovery method

  1. In these cases, the incision method is much more stable

• Eyes with a lot of fat, where the line easily loosens

• Accompanied by sagging

• Weak eye-opening force

• When line width adjustment is needed

In other words, not the method,

but the internal structure of the eye is the primary criterion.

  1. The way to reduce left-right differences in eyelid surgery: ‘measurement’ and ‘movement analysis’

Mokdong Plastic Surgery Recommendation: Eyelid Surgery

Most eyes are not exactly symmetrical left to right.

That is why adjustments in 0.1 mm units are necessary.

After observing how muscle movement changes while the eyes are opened, closed, and moved up, down, left, and right, the fixation point is determined.

What creates the result is not ‘design’ but ‘measurement + functional analysis’

• Eyebrow position

• Angle of the eye-opening muscles

• Skin laxity

• Fat position

• Direction of tension

The process of finding the point where these values align

is the core of eyelid surgery.

  1. Frequently asked questions

Mokdong Plastic Surgery Recommendation: Eyelid Surgery

Q1. Does a 0.1 mm difference really look that big?

It does.

Because the eyelid structure is sensitive,

even a subtle difference determines the flow of the line and the impression.

Q2. I thought it was enough to just make the line pretty... do we really need to look at the muscles?

The line is the ‘result,’

and the muscles are the ‘cause’ that allows the line to be maintained,

so both need to be considered together to make it natural.

Q3. Is the non-incision method more natural?

It depends on the structure of the eye.

The non-incision method can be more natural,

and the incision method can also be more natural.

  1. To sum up

Mokdong Plastic Surgery Recommendation: Eyelid Surgery

The phrase “the secret of 0.1 mm” means

that eyelid surgery is a procedure in a very delicate area.

Rather than looking only at the surface of the eye,

it considers the skin, fat, muscle, and fascia together,

and adjusts them in very small increments,

so small changes can alter the overall impression.

When considering eyelid surgery,

what is more important than the shape of the line is

first understanding the movement and function of the eyes.
