In order to avoid lateral canthus contraction, some doctors separate the bulbar conjunctiva on both sides, stretch and fix it on the skin on both sides, or cut off too much skin on the lateral canthus, which not only causes excessive damage, but also causes bulbar conjunctiva irritation because there is no skin maintenance on both sides.
2. Disadvantages of post-operative canthus contraction.
Because of the unique structure of the upper eyelid, it is very easy to cause edema and hyperplasia, scar muscle atrophy and adhesion after the operation of the outer corner of the eye, which leads to the contraction of the upper eyelid after the operation. It is possible that as the upper eyelid becomes more and more round, even the eyelid cleft will be shortened laterally.
3. The scar of eye opening injury is heavier.
Opening the corner of the eye is likely to cause scar injury, because the surgical treatment of opening the corner of the eye, like other surgical treatments, will leave a wound, but this wound is not easy for doctors to hide. Therefore, many beauty seekers have obvious scars on both sides of their eyes after surgery on the outer corner of their eyes.
