A foreign body in the eye depends on the location of the foreign body. If the foreign body is only on the surface of the eye and has not invaded the inside of the eye, in this case, the foreign body can be removed in an outpatient clinic and then given anti-inflammatory treatment. However, if it is a foreign body inside the eye or a foreign body in the wall of the ball, this is a more serious trauma. In this case, the foreign body should first be surgically removed from the wall of the ball or the ball in a regular hospital, and then antibiotics should be applied to the eye and the local and systemic areas to avoid intraocular infections as much as possible. Once an intraocular infection occurs, it can have a very serious impact on visual function, and the virulence of the infected bacteria may even lead to loss of vision or even the removal of the eye if it is strong. Therefore, if there is a foreign body in the eye, it is important to go to a regular hospital for examination as early as possible.
