Because of the characteristics of our oriental eyes, we still have a very large proportion of canthus surgery. During normal double eyelid surgery's procedure, more than 80% patients may need canthus surgery at the same time. What surgery is needed? We can use our own, slight evaluation to gain understanding. For example, we make one. To calculate the facial proportion, we say that the aesthetic proportion is called three courts and five eyes, and the width of our whole face should be five eyes. The relationship between the lengths, the distance between the inner canthus, should be equal to the length of an eye. At this time, if it is wider than the length of one eye, it may be necessary to have major surgery on the inner corner of the eye.

The other is from the exposure of our tears. For example, we see that many patients with epicanthus can't see when they open their eyes. The tear mark in the corner of our eyes is a pink protruding shape. This tissue is called lacrimal gland. If you can't see it, it's called this epicanthus.
