What Is Corneal Laceration?

The cornea is the clear front window of the eye. A corneal laceration is a cut on the cornea. It is usually caused by something sharp flying into the eye. It can also be caused by something striking the eye with significant force, like a metallic hand tool. A corneal laceration is deeper than a corneal abrasion, cutting partially or fully through the cornea. If the corneal laceration is deep enough it can cause a full thickness laceration. This is when the laceration cuts completely through the cornea and causes a ruptured globe, a tear into the eyeball itself.

A corneal laceration is a very serious injury and requires immediate medical attention to avoid severe vision loss.

If your eye has been injured, you should do the following:

  • gently place a shield over the eye to protect it. Cut away the bottom part of a paper cup and tape this piece to the area around the eye. Wear this to protect your eye until you get medical help.
  • do not rinse with water
  • do not remove the object stuck in eye
  • do not rub or apply pressure to eye
  • avoid giving aspirin, ibuprofen or other non-steroidal, anti-inflammatory drugs. These drugs thin the blood and may increase bleeding
  • after you have finished protecting the eye, see a physician immediately
