What is Keratoconus? Understanding the Causes, Symptoms, and Treatment Options

What is Keratoconus?

Keratoconus is an eye condition that affects the clear front part of your eye, called the cornea. Normally, the cornea is round and smooth. However, with keratoconus, the cornea becomes thin and bulges outward into a cone shape. As a result, vision can become blurry or distorted. This condition often starts in the teenage years or early adulthood. Although it can get worse over time, early treatment can help manage symptoms.

Symptoms of Keratoconus

Early on, keratoconus symptoms may be mild. Over time, they can become more noticeable. For example, you may notice changes in your vision that glasses cannot fix. Common symptoms include:

  • Blurry or distorted vision
  • Increased sensitivity to light and glare
  • Frequent changes in eyeglass prescriptions
  • Difficulty seeing at night
  • Double vision in one eye
  • Seeing halos around lights

    • Because these symptoms can be similar to other eye problems, it is important to see an eye doctor for a proper diagnosis.

    Causes and Risk Factors

    Doctors do not know the exact cause of keratoconus. However, several factors may increase your risk. For instance, genetics can play a role, as the condition sometimes runs in families. Other risk factors include:

  • Frequent eye rubbing
  • Having certain allergies
  • Conditions like asthma or eczema
  • Family history of keratoconus
  • Some connective tissue disorders

    • While anyone can develop keratoconus, it often starts in teens or young adults. Early detection can help slow its progress.

    How Keratoconus is Diagnosed

    Eye doctors use several tests to diagnose keratoconus. First, they will ask about your symptoms and family history. Then, they will check your vision and examine your eyes. Common tests include:

  • Corneal topography: This test maps the shape of your cornea. It can show even small changes.
  • Pachymetry: This measures the thickness of your cornea.
  • Slit-lamp exam: The doctor uses a special microscope to look for signs of keratoconus.

    • Because early keratoconus can be hard to spot, regular eye exams are important. If you notice vision changes, see an eye care specialist right away.

    Treatment Options for Keratoconus

    Treatment for keratoconus depends on how severe your symptoms are. Early on, glasses or soft contact lenses may help. As the condition progresses, other options may be needed. These include:

  • Rigid gas permeable lenses: These hard lenses can improve vision by covering the irregular cornea.
  • Scleral lenses: These larger lenses rest on the white part of your eye and can be more comfortable.
  • Corneal cross-linking: This procedure uses special drops and light to strengthen the cornea. It can slow or stop keratoconus from getting worse.
  • Intacs: These are small implants placed in the cornea to help flatten its shape.
  • Corneal transplant: In severe cases, doctors may replace the damaged cornea with a healthy one from a donor.

    • Because treatment options vary, it is important to talk to your doctor about what is best for you. If you are looking for keratoconus treatment in your area, ask your eye care provider for recommendations.

    Living with Keratoconus: Lifestyle Tips

    Although living with keratoconus can be challenging, there are ways to protect your vision. For example, you can:

  • Avoid rubbing your eyes, as this can make the condition worse
  • Wear sunglasses to protect your eyes from bright light
  • Follow your doctor’s advice about contact lens care
  • Keep up with regular eye exams
  • Tell your doctor about any changes in your vision

    • With the right care, many people with keratoconus can lead active lives.

    Prevention and Early Detection

    While you cannot always prevent keratoconus, early detection can help. For instance, regular eye exams can catch changes before they become serious. If you have a family history of keratoconus, tell your eye doctor. Also, avoid rubbing your eyes, especially if you have allergies. Early treatment can slow the condition and protect your vision.
