Treatment of foreign bodies can begin at the site of the injury. Chemicals or small debris in the eye may be removed by rinsing the eye thoroughly with water. Some good options for rinsing the eye include:
The eyelids must be held apart so that all parts of the eye are washed. This washing must be done within minutes of the injury. The corner of a facial tissue or the tip of a cotton applicator may be used to remove any remaining small debris. The bottom of a paper cup can be taped over the eye to protect it from further injury.
Large foreign bodies or metal objects should be removed by the healthcare provider. The eye may be numbed with a local anesthetic. A cotton-tipped applicator moistened with saline or salt water may be used to remove the material. If this does not work, the object can be removed, under the microscope, with a small instrument. Once the object has been removed, antibiotic drops or ointments may be prescribed to prevent infection.
Drops, ointments, and oral antibiotics may cause allergic reactions or irritation.
Most of the time, treatment is effective, and the person has no long-term effects from the injury. Severe injuries, however, may cause permanent visual impairments .
Sometimes the injured area will not heal, and the person will have recurrent corneal injuries. Antibiotic drops and rewetting drops to keep the cornea wet will usually help the eye heal. Frequent rewetting of the cornea is necessary, over months, to allow this area to heal completely. Any new or worsening symptoms should be reported to the healthcare provider.
