At present, there are not many experts with excellent double eyelid repair technology in China, because the difficulty of double eyelid repair surgery is much higher than that of double eyelid surgery for the first time, and the responsibility is heavier, and most plastic surgeons mainly focus on double eyelid plastic surgery. The authoritative expert of double eyelid repair in China should be Wang Zhenjun of Meian, who is also a direct disciple of Cao Renchang, the Asian Eye King of China. He devoted himself to failed eye plastic surgery and successfully repaired many cases of extremely failed double eyelids.
