Suspicion of foreign bodies which cannot be visualised merit radiological investigation (plain X-ray or CT).
Management of a lid laceration should include:
Irrigation: the laceration should be copiously irrigated with normal saline to clear debris and prevent infection
Tetanus: confirm tetanus status and follow local guidelines
Antibiotics for any surrounding cellulitis
Horizontal and small, simple lacerations away from the lid can be managed laissez-faire or with cyanoacrylate glue
All complex lacerations should be referred following initial treatment for specialist repair
