A corneal abrasion is a scratch or injury to the transparent surface of the eye, called the cornea. This injury, although usually minor, can be very uncomfortable and requires appropriate care to avoid complications.
Causes and symptoms
Corneal abrasions can be caused by a variety of factors, including:
• Excessive rubbing of the eyes, especially in the presence of a foreign body.
• Dust, sand or other particles entering the eye.
• An accidental blow to the eye with an object, tree branch or fingernail.
• Incorrect or prolonged wearing of contact lenses.
Symptoms include:
• Pain or burning sensation.
• Redness of the eye.
• Increased sensitivity to light (photophobia).
• Blurred or hazy vision.
• Excessive tearing.
• Sensation of a foreign body in the eye.
What to do in case of corneal abrasion?
If you think you may have a corneal abrasion, here are a few steps to take:
• Avoid rubbing your eye: this could aggravate the injury.
• Rinse your eye with clean water: This will remove the particles responsible for the irritation.
• Blink several times: This can help expel small particles trapped under the eyelid.
• Avoid wearing contact lenses until the eye is completely healed.
• Use lubricating drops (artificial tears) to soothe the eye.
• Consult an optometrist if pain persists, vision is affected or the eye appears infected.
What not to do
• Do not apply medicated eye drops without the advice of your optometrist.
• Don't try to remove a deeply embedded foreign body.
• Do not use sharp objects or cotton buds to clean the eye.
• Do not wear contact lenses until you have obtained advice from your optometrist.
Treatment and recovery
However, more severe cases may require antibiotic drops or ointment to prevent infection. In some cases, an eye patch may be recommended to reduce irritation.
Preventing corneal abrasions
• Wear protective eyewear when working in dusty environments or with chemicals.
• Handle contact lenses with care and follow care instructions.
• Avoid rubbing your eyes with dirty hands.
• Use artificial tears if your eyes are dry, to reduce the risk of microtrauma.
By taking these precautions and acting quickly in the event of corneal abrasion, you'll protect your vision and promote rapid healing. If you experience intense pain or deterioration of vision, don't hesitate to consult an optometrist.
