First aid
Try to flush the foreign body out of your eye with lukewarm tap water. If you still have a foreign body feeling the next morning, you should present yourself to an ophthalmologist.
Treatment by an ophthalmologist
Anesthetic eye drops are used so that the eye can be examined in detail. The foreign body stuck in the cornea, conjunctiva or under the eyelid is carefully removed with a pointed instrument. Metal foreign bodies made of steel or iron often leave behind rust in the cornea, which can be removed with a small drill.
Antibiotic-containing eye drops are then prescribed to prevent infections. To reduce scar formation, eye drops containing cortisone may also be prescribed later. As long as the wound is not completely healed, contact lenses should not be worn.
