Complications are rare with eyelid surgery but can include hematoma from retraction of a vessel after eyelid surgery. Hematomas should be treated urgently. Other complications include lagophthalmos due to over-resection of eyelid skin. Treatment with massage can improve lagophthalmos or a skin graft.
Other side effects include eyelid skin webbing, conjunctivitis, chemosis, a hallowed appearance, double vision, infections, suture granuloma, excessive tearing, lateral canthal rounding, and eyelid malposition.
