Since a Lateral Canthoplasty is a surgery that includes an incision, yes it would leave a scar. But it isn't the type of scar that is really disturbing to look at. This kind of scar would start to heal 3 months after the surgery till it wouldnt leave any. For some cases, when it takes longer to heal than usual, some patients would get what we call the scar removal injection. This surgery is not a risky type of surgery which will be done with 45mins- 1hr.Hi has anyone undergone lateral canthoplasty? I'm interested in it but I heard its kinda risky (despite some clinics sayings it's not)?
