Corneal abrasion

Corneal abrasion

A corneal abrasion, often described as a scratched eye, is one of the most common eye injuries. While usually not serious, it can be painful and potentially lead to complications if not properly treated.

Let’s explore what corneal abrasions are, their causes (including the link to contact lens use), symptoms, treatment options, and prevention strategies.

 

What is a corneal abrasion?

The cornea is the clear, protective outer layer of your eye. A corneal abrasion occurs when this layer is scratched or damaged. Think of it as a scratch on the surface of your eye – ouch!

 

Common causes

Corneal abrasions can happen in various ways:

  1. Foreign objects in the eye (dust, sand, metal particles)
  2. Rubbing eyes too hard
  3. Sports injuries
  4. Fingernail scratches
  5. Makeup brushes or applicators
  6. Contact lens-related issues

 

The contact lens connection

While contact lenses are a safe and effective vision correction method for millions, they do come with some risks, including an increased chance of corneal abrasions. Here’s why:

  • Extended wear: Wearing lenses longer than recommended can dry out your eyes and increase friction.
  • Improper handling: Inserting or removing lenses with long nails or rough handling can scratch the cornea.
  • Poor fit: Ill-fitting lenses can move around too much, potentially causing irritation or abrasions.
  • Debris trapped under the lens: Particles can get caught between the lens and your eye, leading to scratches.

It’s crucial to note that these risks are generally minimal when proper care and hygiene practices are followed.

 

Symptoms to watch out for

If you suspect a corneal abrasion, look out for these symptoms:

  • Feeling like something is in your eye
  • Pain, especially when opening or closing your eye
  • Sensitivity to light
  • Redness in the affected eye
  • Tearing and blurry vision
  • Headache

 

Treatment options

Most corneal abrasions heal on their own within a few days. However, it’s always best to have an eye care professional assess the injury. Treatment may include:

  1. Antibiotic eye drops to prevent infection
  2. Lubricating eye drops for comfort
  3. Pain relief medication
  4. Temporary eye patch for severe cases

 

Prevention strategies

To reduce your risk of corneal abrasions:

  1. Wear protective eyewear during sports or DIY projects
  2. Be gentle when rubbing your eyes
  3. Keep your fingernails trimmed
  4. For contact lens wearers:
    • Follow proper hygiene and care instructions
    • Replace lenses as recommended
    • Don’t sleep in your lenses unless specifically designed for extended wear
    • Have regular check-ups with your eye care professional

 

When to seek professional help

While many corneal abrasions heal on their own, you should consult an eye care professional if:

  • Pain persists or worsens
  • You experience vision changes
  • The injury was caused by a chemical or a contaminated object
  • You wear contact lenses and suspect an abrasion

 

Conclusion

Corneal abrasions, while common, can be painful and potentially serious. By understanding the causes, including the risks associated with contact lens use, you can take steps to protect your eyes.
