Keep the head tilted back – never forward as gravity will work to drain the intraocular fluid. Do not put any pressure on the eye. Ideally you would like to gently tape a small cup, like a Dixie cup, over the eye. If the object is protruding from the eye (like a nail), do not attempt to remove it. Go to the nearest emergency room, calling ahead if possible to tell them what has happened and to please alert their on-call ophthalmologist. This is obviously an ocular emergency.
