I have read dr comments that 5 days is long enough for suture removal.
in my practice are removed between 3 and 5 days, primarily to avoid the development of small whitehead (milia) or scars from the sutures themselves. But its done at the risk of the wound separating but it has never been a problem for me.
Every surgeon has a different operative technique and protocol for when they prefer to remove sutures after eyelid surgery. Typically sutures can usually be removed between 5-7 days after surgery. If the sutures are removed too early, the healing incision is weak and can easily open up. While 11 days is on the longer side for for suture removal, eyelid skin is very thin and incisions typically heal very well in most patients.
