Most intraocular foreign bodies do not expel themselves. When a foreign body is embedded or adhered to the corneal surface, it is important not to rub the eye with your hand to avoid touching the foreign body and aggravating the depth of the embedding, which can become infected and cause corneal inflammation. It is therefore necessary to receive regular treatment in hospital. If the foreign body has entered the eye, it should be seen in the ophthalmology department of the hospital and, if necessary, the foreign body should be removed from the eye.
