Inner Double Eyelid Surgery Guide: Natural Adhesion vs. Incision Method, Which Line is Right for Me?
The appropriate method for inner double eyelid surgery varies depending on the individual's eye shape and skin thickness. From a natural in-line to a defined in-out line, it is important to clearly understand the difference between natural adhesion and the incision method to find the 'Custom Fit' line that suits you best. Learn in detail about the eye surgery standards and safety systems proposed by a specialist with 22 years of experience.

Characteristics of Inner Double Eyelid Surgery for a Natural Impression
Eyes with double eyelids tend to give a clearer and softer impression compared to monolids. Recently, rather than unconditionally large and glamorous eyes, there is a growing preference for inner double eyelid surgery that corrects the eye shape while preserving one's individuality. Even for the same eye surgery, it can be divided into various types, from a natural in-line to a defined out-line, depending on the desired style. The results can also vary depending on the presence of an incision and the method used to create the line.

At 345 Plastic Surgery, we do not just follow trends; we aim for 'Custom Fit Double Eyelids' that find the most harmonious line by reflecting each individual's anatomical characteristics.

Choosing a Surgical Method: Natural Adhesion vs. Incision Method Comparison
To determine the most suitable inner double eyelid surgery method for you, it is necessary to accurately assess the condition of your eyelids. The characteristics of the two representative methods are as follows:

- Natural Adhesion: Suitable for those who want a natural line whether their eyes are open or closed. It is recommended for individuals with less eyelid fat and thin skin, allowing for fixation without an incision, and has the advantage of a relatively quick recovery.
- Incision Method: Performed when a clear and defined line is desired, or when strong fixation without the worry of the fold loosening is needed. More stable results can be expected if there is a lot of eyelid fat or thick skin that requires the removal of unnecessary tissue.

Types of Double Eyelid Lines That Suit Me
The height of the starting and ending points varies depending on the shape of the eye, which greatly affects the overall image.
- In-line: A shape that starts with a portion of the Mongolian fold at the front of the eye covered. It is the most similar to inner double eyelid surgery and looks very natural.
- Out-line: A line that starts higher up than the inner corner of the eye, giving a Westernized and glamorous feel.
- In-out line: An intermediate form between the in-line and out-line. It is a sophisticated line that starts naturally from the inner corner and gradually widens toward the outer corner.

Extensive Experience and Safety-Oriented Medical System
Because the results of eye surgery can change with even the slightest difference, the proficiency of the medical staff is extremely important. Dr. Song In-soo of 345 Plastic Surgery pursues both aesthetic sense and functional stability simultaneously, based on 22 years of surgical experience.

In addition, for the peace of mind of our patients, we prioritize safety by operating a 'Doctor Call System' where the operating surgeon personally checks the patient's condition the day after surgery, and a 'Ghost Surgery Prevention System' through 24-hour CCTV operation.
