Epicanthoplasty is a rare eye surgery to modify the epicanthal folds. It can be a challenging procedure because the epicanthal folds overlay the lacrimal canaliculi (tear drainage canals).[1]
Although an epicanthic fold can also be associated with a less prominent upper eyelid crease (a feature commonly termed "single eyelids" as opposed to "double eyelids"), the two features are distinct; a person may have both epicanthal folds and an upper eyelid crease, one and not the other, or neither.[2] Single eyelids are reshaped using East Asian blepharoplasty.[citation needed]
Epicanthoplasty may leave visible post-surgical scar lines. A common corrective technique involves using Z-plasty. [citation needed]
