Your cornea is the clear layer on the front of your eyeball. It focuses light and helps protect your eye from dust and germs. A foreign object can get into the cornea itself. A trapped speck of dirt or grit is often a minor problem. But anything metal, or an object that goes through (pierces) your cornea, can cause severe damage.
The longer you wait, the greater the chance of injury or infection. Seek emergency medical help right away for any of the following:
An object in your eye that you can't flush out with water
Your eye remains very swollen or painful after an object has been removed
An object embedded in your eye. Cover both eyes with a sterile compress and call 911.
The front of your eye (cornea) is white or hazy
Blood in your eye
You are having trouble seeing
A healthcare provider will ask about your injury and examine your eye.
You may be given eye drops to ease any mild pain.
The provider will use a microscope with a bright light to help examine your eyeball. He or she may put a special dye (fluorescein dye) on the cornea to help see the object more clearly.
The provider may remove a loose foreign object.
Severe injuries are likely to be treated by an eye specialist (ophthalmologist).
Call your healthcare provider if you notice any of these symptoms after going home:
Fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider
Increased redness or eye pain
Drainage from your eye
Blurred or decreased vision
