Most East Asians have a single, bloated upper eyelid with lax skin and canthus. In patients without medial canthus, blepharoplasty alone can result in larger eyes, but in patients with moderate to severe medial canthus, the presence of medial canthus may severely diminish the postoperative results. For this reason, an inner canthoplasty can be performed at the same time as the blepharoplasty. The inner canthoplasty is performed by removing the excess inner and outer canthus to change the inner canthus or to lengthen the eye fissure and reveal the pink tear ducts that lie deep within the inner structure of the eye, thereby increasing the size of the eye fissure and making the eyes larger, more luminous and brighter. The purpose of blepharoplasty to correct the inner canthus at the same time is the following: 1. to fully eliminate the webbed skin formed by the inner canthus, completely exposing the inner corner of the eye and the tear trough, so that the inner canthus does not recur after surgery; 2. no obvious scar will be formed in the inner canthus; 3. to form a natural and smooth articulation with the heavy eyelid line, completely eliminating the pulling influence of the inner canthus on the heavy eyelid line.
