Keratoconus

Keratoconus Treatment

A healthy cornea is round. If your cornea thins and can no longer hold its shape, it can bulge into a cone shape, which is a condition called keratoconus. This condition occurs mostly in people between the ages of 10 and 25, and it can progress slowly for 10 years or longer. At NewVision Eyecare in Sammamish, WA, we provide treatment options for this condition.

Who Is at Risk for Keratoconus?

Although anyone can develop this condition, certain factors can increase your risk of getting it. These include:

  • A family history of keratoconus
  • Vigorous rubbing of the eyes
  • Having retinitis pigmentosa
  • Having hay fever
  • Having asthma

What Are the Symptoms of Keratoconus?

In the early stages, keratoconus often causes no symptoms. As the condition progresses, this condition can cause painless symptoms that affect your vision. These include:

  • Blurry or distorted vision
  • Sensitivity to bright lights
  • Difficulty driving at night
  • Needing recurrent changes in your eyeglass prescription
  • Sudden worsening of vision
  • Sudden clouding of vision

How Is Keratoconus Diagnosed?

This condition can be detected at a routine eye exam. During the exam, our eye doctor will perform a refraction and a slit-lamp exam to evaluate the shape of your cornea and detect any potential eye problems. If we suspect keratoconus, we will perform further tests.

  • Keratometry: During this test, our optometrist will focus a circle of light on your cornea to measure the reflection, which will determine the shape of your cornea.
  • Computerized corneal mapping: This is a photographic test that is designed to create a detailed map of your cornea. Keratoconus can be detected using this method before it is visible on a slit-lamp exam.

How Is Keratoconus Treated?

The treatment method our eye doctor chooses depends on the severity of your condition and how rapidly it is progressing. The most common treatment options include:

  • Eyeglasses: Our eye doctor can increase your eyeglass prescription to help with blurry and distorted vision.
  • Gas permeable lenses: Gas permeable lenses are hard, and they can hold your cornea's round shape, which will correct your vision.
  • Piggyback lenses: If gas permeable contacts are uncomfortable, our optometrist can prescribe a soft lens to wear underneath the hard lens to provide some cushion.
  • Hybrid lenses: Hybrid lenses are another option if you cannot get used to gas permeable lenses. These lenses are hard in the center and have a soft outer ring, which provides more comfort.
  • Scleral lenses: These lenses rest on the white of your eye and vault over the cornea. Sincethey won't touch the cornea, they will fit well and improve your vision.
  • Ortho-K: This involves wearing specialized contact lenses at night to reshape the cornea. In the morning, you should be able to see clearly.
