Opening the corner of the eye is a minimally invasive surgical method to enlarge the inner corner of the eye, which can lengthen the eye fissure, shorten the eye distance and achieve the cosmetic effect. This operation can also be called extraocular canthoplasty, which is generally suitable for cases with small eye fissure and epicanthus. At present, canthus surgery is a relatively small cosmetic surgery, which is relatively mature and common, and can be performed in plastic surgery departments of general plastic surgery hospitals or public hospitals. The commonly used surgical methods are "Z" plasty or "Z-Y" suture. If you want to open your eyes, you can go to the plastic surgery department of a local public hospital or a regular plastic surgery hospital, choose standardized treatment, and pay attention to dressing change and nursing after surgery.
