The treatment for a foreign body in the eye that won’t come out includes natural irrigation and removal of the foreign body under a slit lamp. 1. Natural flushing: If a foreign body is in the eye and cannot come out, sterile saline can be used to flush the eye. If the foreign body sensation disappears after natural flushing, levofloxacin eye drops can be used for preventive anti-inflammation. If the foreign body sensation does not disappear after natural rinsing, it is necessary to go to the hospital in time to see a doctor and remove the foreign body under the slit lamp. 2. Remove the foreign body under slit lamp: The doctor will use the slit lamp to observe the location of the foreign body, and then remove the foreign body under the slit lamp. After the foreign body is removed, topical levofloxacin eye drops are also needed for preventive anti-inflammation. Topical levofloxacin ophthalmic solution should be used under doctor’s supervision, and it is not recommended to use the medication privately.
