Hello, I’m Dr. Choi Seung-hyeop, the director of Wink Plastic Surgery. Today, I’ll explain the procedure known as outer-and-lower canthoplasty, also called dual canthoplasty, which is performed to expand the white area at the outer part of the eye.

In what cases is dual canthoplasty (outer-and-lower canthoplasty) recommended? It may be considered for people who want to enlarge the eyes and achieve longer, more refreshed-looking eyes along with double eyelid surgery, as well as for those with upward-slanting outer corners.

So what is the effect of outer-and-lower canthoplasty (dual canthoplasty)? First, by pulling and expanding the outer corner of the eye and the lower eyelid, the visible white of the eye at the outer side increases, and in cases with upward-slanting eyes, part of the eye angle can be changed.

Then why are outer-and-lower canthoplasty (dual canthoplasty) procedures performed together? In the past, outer canthoplasty alone was commonly performed, but recent studies have shown that combining it with lower canthoplasty can produce a greater effect. As a result, they are sometimes done together, but in some cases only one procedure may be performed, so it would be good to receive a diagnosis through consultation.

Are there any special precautions for dual canthoplasty? As with all canthoplasty procedures, doing too much is not good aesthetically or functionally. If you have dry eyes, it is better not to open the outer corner too much, and if the outer corner of the eye is already drooping, it is better not to perform lower canthoplasty.
