What is polymer double eyelid surgery? The so-called polymer double eyelid surgery is actually the double eyelid surgery with buried thread. The polymer material is to replace the general surgical suture with nylon thread. Can taking out stitches in three days make the incision marks inconspicuous? Whether the incision marks are obvious or not does not depend on whether the stitches are removed a few days earlier or later, but mainly depends on the fineness of the operation. Rough operation, irregular incision, imprecise suture, dislocation of suture, thick needle and early suture removal, for fear that the knife edge will inevitably leave obvious marks. Three days is only the initial healing of the wound, the cortical healing is not firm, and the deep healing is even more unrealistic. The double eyelid line will shift with the more eye-opening activities. In order to make the operation better, it is best to remove the stitches in 5 to 7 days.
