External canthus surgery is a simple and commonly used lateral canthoplasty. < P > The operation on the outer corner of the eye can make the blepharoptosis get permanent enlargement. However, the operation on the outer corner of the eye is limited to a large extent. If the incision of the outer canthus is too large, and the vault and bulbar conjunctiva are not relaxed enough, and the incision is forcibly sutured, the red edge of bulbar conjunctiva will appear in the area where the canthus angle is wide, which will affect the appearance and cause palpebral fissure insufficiency. Simple microphthalmia only needs to be performed at the same time. If blepharoptosis is associated, blepharoptosis can be corrected after 6 ~ 12 months.

the effect of surgery on the outer corner of the eye is related to the doctor's skill, which is not inevitable. Surgery on the outer corner of the eye can enlarge the fissure of the eye and play an auxiliary role in the drooping of the corner of the eye, but the significance is not great. Moreover, the incision is easy to heal, so some effects are not very good. And because the operation is difficult, I suggest you go to a regular hospital for surgery on the outer corner of your eye. Only in this way can the operation be carried out safely and smoothly.
