Keratoconus is a condition of the eye that affects the shape of your cornea. A healthy cornea is round and shaped like a dome. If you have keratoconus, your cornea will gradually bulge out into the shape of a cone. If you have this condition or suspect that you do, there are a few things that you should know.

Who is at Risk Of Developing Keratoconus

Doctors don't know what causes this condition; however, there are a few factors that put you at greater risk.

  • Family history

  • Frequent rubbing of the eye

  • Down syndrome

  • Ehlers-Danlos syndrome

  • Hay fever

  • Asthma

  • Retinitis pigmentosa

What Are the Symptoms of Keratoconus?

In the early stages of this condition, you may not experience any symptoms. The signs and symptoms may change as the disease progresses. The symptoms include:

  • Blurry vision

  • Distorted vision

  • Sensitivity to bright light and glare

  • Difficulty seeing at night

  • Sudden worsening of the vision

  • Cloudy vision

  • Frequent changes in your eyeglass prescription

How is Keratoconus Diagnosed?

There are a few tests that your eye doctor will perform to diagnose this condition.

  • Slit-lamp exam: Your optometrist will use a low-powered microscope to view your eye. They will evaluate the shape of the cornea to check for abnormalities.

  • Keratometry: During this test, your optometrist would focus a circle of light on your cornea. This allows them to measure the reflection to determine the shape of your cornea.

  • Computerized corneal mapping: This test can create a detailed shape map of the surface of your cornea. It also measures its thickness.

How Is Keratoconus Treated?

There are several treatment methods for this condition. The treatment that your optometrist will recommend would determine on your eyes and the severity of your condition.

  • New prescription: In the early stages of the condition, your eye doctor can give you a new eyeglass or contact lens prescription to correct the blurry or distorted vision.

  • Gas permeable lenses: Gas permeable lenses are rigid and hold their shape. This makes it possible for them to keep the round shape of your eye.

  • Piggyback lenses: If you find that gas permeable lenses are uncomfortable, piggyback lenses can help. This is where you put a soft pair of lenses under the gas permeable lens to act as a cushion.

  • Corneal Inserts: This is a surgical procedure where your doctor would place a clear, plastic insert that is designed to flatten the cone shape of your corneas.
