The entire double eyelid line is not obvious and requires redoing the surgery. 2. If the double eyelid line is not obvious. For patients with interrupted eyelid line, only interrupted eyelid line can be interrupted in the inconspicuous part; for patients with partial inconspicuous eyelid line with incision method, the incision can be repaired in the inconspicuous part. 3.Patients with thin eyelids and light inner canthus can be repaired with the buried line method. Patients with swollen eyelids or severe canthal redundancy or obvious upper lid skin laxity should switch to the incision method. When using the incision method, care should be taken to bring the lid or pre-lid fascia, trim the medial canthus, and remove excess upper lid loose skin so that the double eyelid line will be obvious.
