Keratoconus Care at Lone Star Vision


When you look into someone’s eyes, you may naturally assume that those eyes are perfectly spherical in shape –but looks can be deceiving. The transparent tissue of the cornea, the “window” at the front of the eye, often takes on irregular curvatures or contours, as in astigmatism. In some people, the corneas actually bulge out, almost resembling cones. This is keratoconus, and it can cause major refractive errors and other vision problems. Fortunately, you can get treatment for your keratoconus symptoms here at Lone Star Vision.

Keratoconus Symptoms and Causes

The shape of the cornea plays an important role in refracting incoming light so that it can be processed into clear images. A normal cornea has a smooth, consistent curve to it. Individuals with keratoconus, the cornea may be highly irregular, often assuming a cone-like shape. This interferes with refraction to cause severe myopia (nearsightedness), astigmatism, glare sensitivity, and even double vision. Sometimes the tissues of the cornea develop tiny cracks that cause a temporary but acute worsening of vision.

No one is entirely sure why keratoconus strikes certain people, usually starting in early adulthood. But it’s believed that some eyes may suffer from weaknesses in the corneal tissue which may be aggravated by oxidative damage or excessive rubbing of the eyes. Whatever the cause, keratoconus can pose serious challenges to your everyday eyesight.

Turn to Our Optometry Team for Keratoconus Treatment

Lone Star Vision can diagnose keratoconus and prescribe treatments to compensate for its symptoms. Our comprehensive eye exam includes refractive testing, vision testing, and close evaluation of the corneas, allowing us to detect keratoconus easily and accurately. Once we know exactly how the condition is affecting your vision, we can employ keratoconus treatment methods such as:

  • Eyeglasses – Eyeglasses generally do a good job of correcting the refractive errors caused by keratoconus. You may require frequent prescription updates while the condition is progressing.
  • Contact lenses – While standard contact lenses may be able to correct a mild case of keratoconus, more advanced conditions are best served by scleral contacts. Because these lenses extend over the cornea, instead of resting on it, they do a great job of compensating for irregular corneal curvature.

Even if your keratoconus cannot be adequately corrected with glasses or contacts, don’t panic. We can refer you to a specialist for implanted devices and other advanced treatments to help you enjoy clear vision.
