Keratoconus Q & A

Cascade Vision Center

What is keratoconus?

Keratoconus is an eye condition that affects the shape of your cornea. Your cornea is the dome-shaped surface of your eye that helps focus light to your retina for clear, crisp vision.

If you have keratoconus it means the center of your cornea has thinned out, causing it to bulge and create a cone-shape. This affects light refraction to your retina, leading to vision changes.

Keratoconus affects about 1 in 2,000 people in the United States, and usually develops when you’re in your teens or early 20s. Researchers are still investigating why some people are more susceptible to the eye condition than others, but theorize it may be a combination of genetic, environmental, or hormonal factors.

What types of vision changes occur with keratoconus?

The vision changes you experience with keratoconus can vary depending on the extent of the corneal change, and may even be different in each eye.

Common vision changes include:

  • Blurred vision
  • Sensitivity to light and glare
  • Eye swelling and redness
  • Myopia (nearsightedness)
  • Astigmatism, when your eye can’t focus
  • Being unable to wear contact lenses


Keratoconus is a progressive disease that worsens over time, in most cases over the course of several years. Your eye care specialist at Cascade Vision Center can determine if your vision problems are due to keratoconus during your comprehensive eye exam by measuring the curvature of your cornea.

How is keratoconus treated?

Treatment for your keratoconus depends on the severity of your symptoms. During the early stages of the condition, your doctor at Cascade Vision Center can correct your vision with eyeglasses or special keratoconus soft or rigid gas permeable contact lenses.

The progression of keratoconus usually slows down as you get older. But if glasses or contact lenses are no longer effective at improving your vision, your specialist at Cascade Vision Center may recommend surgical intervention, such as:

  • Intacs, a surgically implanted device that helps flatten the curvature of your cornea
  • Corneal transplant


The most important thing if you have keratoconus, however, is that you make a conscious effort not to rub your eyes. Rubbing may damage your already thin cornea and worsen your vision.
