If you've ever looked through an oddly-curved piece of glass or clear plastic, you probably saw a pretty distorted view of the world. That's the kind of problem you experience when you have the eye disorder known as keratoconus. If your corneas are bulging outward and interfering with your vision, you should know that the proper treatment can help you compensate for this difficult challenge. Here at Primary Eyecare and Optical of Meridian, we can help you see clearly again.
Keratoconus is a condition in which your corneas take on a cone-like shape instead of the usual smooth semi-spherical curvature. This is a serious problem as far as the refraction of incoming light is concerned. A normal corneal curvature helps to direct the light toward the back of the eye so it can make sharply-focused images. A cone-shaped cornea interferes with this function so that the light enters in irregular patterns and falls far short of the back of the eye. The result is usually a combination of severe astigmatism and myopia (nearsightedness).
Keratoconus can be more difficult to correct than other refractive disorders. In addition to the severity of the visual distortion it creates, the odd shapes of the corneas can make ordinary soft contacts a less-than-effective solution because the contacts simply conform to the irregular curvature instead of compensating for it. In some cases, the corneas may occasionally split, causing periods of even more severe vision trouble.
It's hard to say why people develop keratoconus. UV exposure, oxidative damage, eye rubbing, and family history of the disorder may all be risk factors. Some individuals simply have thin or weak corneal tissue that lends itself to irregularities.
Our Meridian eye clinic can help you fight back against the vision problems caused by keratoconus. We can confirm the condition through a comprehensive eye exam, with corneal mapping and measurement revealing the exact nature and degree of distortion. GP (gas permeable) contact lenses are usually a good starting point for correcting the refractive errors caused by keratoconus. This rigid lens maintains a steady corrective curvature. Hybrid lenses add a soft rim for greater comfort. Scleral lenses are highly effective against keratoconus because they don't rest on the corneas at all -- they rest on the white of the eye and extend completely over the corneas.
