When conversing with others, the eyes are undoubtedly the first place the gaze rests. However, even if the double eyelid lines or the size of the eyes are similar on both sides, if the overall impression appears tilted or unstable, you should suspect a potential issue with the ‘horizontal axis’ of the eyes itself.
Although everyone has subtle differences in facial bone structure, the phenomenon where the imaginary line connecting the inner corner of the eye to the outer corner shows a distinctly different angle on the left and right is called eye axis asymmetry. This is difficult to balance using simple methods that merely increase or decrease the visible skin area.
At Sheone Plastic Surgery, a clinic specialized in eye revision surgery, we examine the anatomical reasons behind this eye axis imbalance and explain in detail the correction principles to regain structural stability through lateral canthoplasty (outer corner lowering).
Primary Factors Disrupting the Horizontal Eye Axis
To successfully achieve eye axis asymmetry correction, it is first necessary to clearly identify the anatomical basis for the tilted axis. The most frequently observed factors clinically are as follows.
Deviation in Left and Right Outer Corner Heights : This is a case where the fixation position on the bone or the tension of the ligaments of both lateral canthus differs, causing one outer corner to be exceptionally high or drooping. The greater this deviation, the more tilted the overall slope of the eyes appears.
Hook Deformity : This is a form where the area around the lacrimal lake at the inner corner of the eye is severely indented and bent downwards like a hook due to previous incorrect surgeries. As the starting point of the inner corner abnormally descends, it simultaneously causes an optical illusion that the outer corner is relatively higher and an actual displacement of the axis.

Because complex structural damages are often intertwined like this, meticulous cause analysis by the medical staff is paramount before deciding on a fragmented surgery.
Restoring Balance Utilizing Lateral Canthoplasty
To balance tilted eyes, a customized surgical plan is established according to the patient’s condition.
Lateral Canthoplasty : This is a core corrective procedure applied when the biggest cause of eye axis distortion lies in the difference in outer corner heights. After precisely dissecting the ligaments and mucosal tissues of the lateral canthus area, they are rearranged outward and downward according to the skeletal structure. By calculating the deviation of both eyes and setting the descending angle and depth differently for the left and right, the horizontal axis can be harmoniously aligned.

Combining Complex Canthoplasty and Reconstruction : If, in addition to outer corner asymmetry, the hook deformity of the inner corner is severe, performing lateral canthoplasty alone has its limitations. In this case, anterior canthoplasty reconstruction is performed to rebuild the collapsed inner corner ligaments, and if necessary, upper canthoplasty (axis rotation) is combined to comprehensively correct the overall tilt of the eyes.

Recovery Process for Stable Engraftment Post-Surgery
As it is a surgery that handles the ligaments and mucous membranes of the eye, proper care must accompany it until the tissues settle stably after surgery.
Stitch Removal and Initial Recovery : After undergoing lateral canthoplasty, stitches are generally removed around 7 to 10 days. During this period, bruising and swelling in the surgical area exist, and chemosis, where the white of the eye swells like jelly, may occur, but this is a natural recovery mechanism.
Tissue Stabilization : Swelling and bruising are gradually absorbed and improve over several weeks. It is advisable to observe the progress with sufficient time until the manipulated lateral canthus ligaments firmly adhere to the new position and the symmetry of the eye axis becomes natural.
Honest Eye Surgery Resolving Structural Causes
The complex caused by a tilted eye axis brings deep stress that cannot be covered by makeup or simple procedures. If you obsess only over reckless eye size enlargement while ignoring your anatomical conditions, it can actually worsen the asymmetry.
Sheone Plastic Surgery insists on 1:1 in-depth consultations based on clinical know-how focusing on eye surgery and high-difficulty revision surgeries. By diagnosing the bone structure, ligament tension, and skin laxity from multiple angles, we exclude unreasonable procedures and propose only honest solutions that can restore the most natural and harmonious impression.
