Inner canthus plastic surgery is to open the inner canthus. Opening the inner corner of the eye is a common eye plastic surgery. To correct microphthalmia, the medial canthus and lateral canthus must be enlarged. If necessary, the medial canthus ligament should be fixed to correct the widening of orbital distance, or blepharoptosis should be corrected. Congenital microphthalmia is characterized by narrow palpebral fissure and serious epicanthus, which is often accompanied by widening epicanthus distance and ptosis. The operation needs to be carried out by stages. The operation period should be in preschool age, when the development of nasal bone has been gradually improved, and the appearance, especially the medial canthus spacing, may be improved.

Clinically, there are mainly V-Y suture, Z-shaped incision and four-valve operation. The former is suitable for mild epicanthus, while the latter is suitable for all kinds of epicanthus. At present, double-V surgery is often used, that is, it can be opened very big and in place, and the entrance can be cleverly hidden, so as to achieve the purpose of leaving no scars after the inner canthus operation. It is an ideal way to make your eyes bigger.
