East Asian blepharoplasty, also known as "double eyelid surgery", is a type of cosmetic surgery where the skin around the eye is reshaped (blepharoplasty). The purpose of the procedure is to create an upper eyelid with a crease (i.e. "double eyelid") from an eyelid that is naturally without a crease (also known as a "single eyelid" or "monolid").

Anatomically, there are a number of subtle differences in the upper eyelids of East Asians, compared with the eyelids of Whites and Blacks. While some East Asians have a double eyelid and some do not, there is also a large variation in the crease position (double eyelid size) of the East Asian upper eyelid. The upper lid fold can range from 1 mm (0.039 in) above the eyelash line to about 10 mm (0.39 in). Several methods can be used to create the double eyelid — including the full-incisional, partial incision and no incision methods (e.g. the DST method). Each has its advantages depending on the patient's anatomy and desires.

East Asian blepharoplasty have been reported to be the most common aesthetic procedure in Taiwan,South Korea and other parts of East Asia and is frequently performed in Northeast Indian states such as Assam. The procedure has been reported to have some risk of complications, but is generally quite safe if done by an expert plastic surgeon. Practitioners of East Asian blepharoplasty include plastic surgeons (facial plastic and reconstructive surgeons), otolaryngologists, oral and maxillofacial surgeons, and ophthalmologists (oculoplastic surgeons). A procedure to remove the epicanthal fold (i.e. an epicanthoplasty) is often performed in conjunction with an East Asian blepharoplasty.

The procedure to alter the natural East Asian "single eyelid" appearance has been a subject of controversy. For example, opponents of the procedure, such as author David Mura, described it as being "indoctrinated by white standards of beauty", although New York-based cosmetic surgeon Dr. Edward Kwak states that many patients who get the procedure done are "not trying to look white", but look like the many Asians who naturally have an eyelid fold. There is also a belief that double eyelids provide a more energetic appearance, and the procedure is popular among high school graduates in China with the view that it will improve their job prospects.
