What sort of problem is a corneal foreign body?

Corneal foreign body: If an object lodges on the surface of the cornea and cannot be removed with simply irrigation, it (the foreign body) causes pain, irritation redness and if iron or copper can rust and lead to staining of the cornea. Removal can be done under topical anesthesia in your ophthalmologists office and should be done as soon as possible.

Foreign body: Any object that lands on the cornea is a foreign body. They can range from eyelashes to metal objects, and everyhting in between. Since the foreign body is not supposed to be there, it causes irritation, and can potentially lead to scars and infections. If an object becomes lodged on or in the cornea and does not release with mild rinsing, you should go to the E.R. Promptly to have it removed.
