If you already have double eyelids and want to remove the Mongolian fold (that is, the double eyelid fold is connected to the eye head), you may consider canthoplasty surgery. The surgery involves opening the Mongolian fold and then suturing it inwardly, thereby opening the corners of the eyes and making the eyes appear larger.
The surgery can be performed under local anesthesia and takes about 15 minutes. Slight eye swelling may occur after surgery, and recovery speed varies from person to person. This surgery is particularly suitable for people affected by ingrown eyelashes to improve the problem of eyelashes stinging the eyeballs. As long as you apply ice and take anti-swelling medicine, the condition will usually return to normal within 1 month.
