Cornea Injuries: What are the Causes and Treatments?

human eye up closeThe eyes are not only our windows to the world but also delicate structures that require meticulous care.

One critical component of our vision is the cornea, a transparent, dome-shaped layer covering the front of the eye. However, this vital part of the eye can be susceptible to injuries that can significantly impact our vision.

In this blog post, we’ll give you insight into the causes of cornea injuries, explore potential treatments, and investigate the promising role of red light therapy in aiding the healing process.

What is Cornea Injury?

The cornea plays a pivotal role in focusing light that enters your eye. It even acts as a barrier, protecting your eye from dirt, dust, and other harmful particles.

However, due to its “exposed position”, your cornea is quite vulnerable to a range of injuries. These injuries can take place in different ways, including:


  • Direct impact to the eye from a projectile or a sharp edge.
  • Scratches from particles like sand or dust.
  • Chemical burns especially from exposure to harmful substances.

Eye surgery complications

  • Bacterial, viral, or even fungal infections can lead to corneal injuries.
  • Contact lens infections are often due to improper cleaning or overuse.

Dry Eye Syndrome

Chronic dryness can sometimes result in the cornea becoming quite irritated and inflamed which can then lead to potential injuries.

UV Exposure

Long-time exposure to ultraviolet (UV) rays without proper protection can cause damage to the cornea, causing conditions like photokeratitis (sunburn of the cornea).

Possible Treatments of Cornea Injuries

When dealing with a cornea injury, correct treatment is a must to prevent complications and preserve vision. The specific approach to treatment depends on the nature and severity of your injury.

When it comes to treating cornea injuries, there are several options you can go for. Each of these treatment methods is tailored to ensure that you can easily tackle any injuries whatsoever.

So, here in this section, let’s take a closer look at these treatments:

Artificial Tears

Think of artificial tears as soothing drops for your eyes. If your eyes feel scratchy, dry, or just feel uncomfortable, artificial tears can work wonders. These are an ideal remedy for minor irritations caused by dust or prolonged screen time.

These drops simply lubricate your eyes, providing instant relief. Plus, they help kickstart the healing process by keeping your cornea moist.

Antibiotics or Antifungal Medications

These antibiotics are usually the most effective remedies of eye treatments, fighting off infections that can harm the cornea.

If your eye is red, or swollen, and you suspect an infection (maybe from wearing dirty contacts or getting something in the eye), these medications can come in handy.

In simple words, just like how antibiotics fight off germs when you’re sick; these eye drops or “ointments” target and kill the bacteria causing the infection. And you even say, these act like the shield of the cornea.

Steroid Eye Drops

Steroid eye drops can do the magic for you! These drops can easily tackle uncomfortable eyes and ease them as much as possible.

When your cornea is all puffy, red, and mostly irritated (maybe from an injury or allergy), these drops can give you the ease you need. Plus, it helps the cornea from getting expert pressure.

These drops even work magic by reducing inflammation. They calm down the redness and help you feel more comfortable. But, like any strong medicine, these are usually used for a short time to avoid any side effects.

Bandage Contact Lenses

Bandage contact lenses can be a great treatment method to prevent any cornea injury. These special contacts act as a shield, protecting the eye as it heals. If you’ve got a scratch or even a minor injury on the cornea, these lenses can act as a barrier against further damage.

Just like a bandage on a cut, these lenses keep the cornea safe from rubbing or any sort of irritation. They give it the space and time it needs to heal without any extra hassle.

Surgical Interventions

When the situation for your cornea is serious, these treatments are like the heavy-duty tools in your doctor’s toolbox. For severe injuries, infections, or even conditions like corneal ulcers, surgery might be the only necessary option to save your vision.

Whether it’s a corneal transplant or a laser surgery, these procedures are designed to fix severe problems.

How Does Red Light Therapy Help with Cornea Injuries?

Red light therapy basically involves exposing the affected area to low levels of red or near-infrared light. This treatment has shown astounding results in promoting tissue repair and reducing inflammation. Here’s how it can help with cornea injuries:

Reduced Inflammation

Red light therapy aids in regulating the inflammatory response, decreasing swelling and pain linked with cornea injuries.

Accelerated Healing

By stimulating cellular activity, red light therapy can easily speed up the healing process of corneal wounds.

Pain Relief

Patients with cornea injuries often experience severe discomfort and sensitivity issues to light. Red light therapy can aid with these symptoms, improving comfort during recovery.

Non-Invasive Nature

Unlike some other treatments, red light therapy for eyes is painless. Plus, it doesn’t involve strong meds or surgery, making it a safe option for many patients.

Improved Corneal Transparency

Studies suggested that red light therapy may contribute to the regeneration of corneal tissue, leading to improved transparency and vision. However, more research is needed to conclude this statement.

Bottom Line

Cornea injuries can have a significant impact on vision and the overall quality of life. From minor irritations to even severe trauma, the range of injuries to the cornea requires different treatments.

However, red light therapy comes as a promising treatment, offering different benefits and even giving the most comfortable treatment of all time.

In a nutshell, whatever you do, make sure you always consult with an expert before going on for any treatment!
