A cornea laceration is the cut on the cornea.
Cornea lacerations are most often caused by something sharp flying into the eye.
They 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.
To close a corneal laceration, it is usual to perform surgery, which helps prevent further damage to the eye and to remove any foreign object that has been embedded in the area after the injury.
Severe lacerations may require several surgeries and may even cause a permanent loss of vision.
A minor scratch should heal on its own in 1 to 3 days.
More severe abrasions may take longer. While your eye heals: Don't rub your eye.
Corneal lacerations are typically caused by cutting wood, trimming grass, grinding metal or other similar activities the edge of a piece of paper can cut through the cornea if enough force is involved, and can usually be prevented by wearing protective eye wear.
Although it is very difficult to see a corneal abrasion with the naked eye, you have to be suspicious of this if you have experienced any of the causes of trauma mentioned above.
Along with that is the unrelenting painful feeling that something is in your eye that just won't wash out, plus: Lots of watery tearing.
Cornea lacerations feel like a grain of sand is trapped in your eye that won't come out.
Your eye is teary, and it stings when you look into the light.
If you have these symptoms, you could have a corneal abrasion, the most common trauma to the eye.
The cornea is your eye's clear, protective outer layer.
Along with the sclera (the white of your eye), it serves as a barrier against dirt, germs, and other things that can cause damage.
Fun fact: Your cornea can also filter out some of the sun's ultraviolet light.
The curvature of this outer layer helps determine how well your eye can focus on objects close up and far away.
If the cornea becomes damaged through disease, infection or injury, the resulting scars or discoloration can interfere with vision by blocking or distorting light as it enters the eye.
