Management of Keratoconus
 |
|
Keratoconus is an irregular protrusion of the cornea, the clear surface over the colored part of the eye. It is similar, structurally, to the crystal of a watch. If this crystal or windowpane is not smooth, the light will not bend evenly and an irregular image will be formed, like looking through a bumpy piece of glass.
In the early stages, eyeglasses or soft contact lenses may be used to correct the mild nearsightedness and astigmatism caused in the early stages of Keratoconus. As the disorder progresses and the cornea continue to thin and change shape, rigid gas permeable (RGP) contact lenses are generally prescribed to correct vision more adequately.
Keratoconus management must take place with a corneal specialist or contact lens specialist who is trained and experienced in handling patients with Keratoconus. Management requires a greater understanding of Keratoconus and a history of treating similar patients diagnosed with Keratoconus. This Keratoconus management often requires cooperation between an ophthalmologist and an optometrist as each provides their specialist knowledge to provide the best possible care.
Keratoconus management can vary depending upon the level of progression of the disease. Mild cases of Keratoconus can often achieve good vision with eyeglasses or soft contact lenses. In these cases Keratoconus management is limited to observing the progression and providing good vision. As the disease progresses, the cornea thin and changes shape. At some point glasses and soft contact lenses will no longer provide the best possible vision. |
