Keratoconus is a non-inflammatory condition that can affect one or both eyes. In patients with keratoconus, the normally rounded dome-shaped cornea which acts as the natural lens of the eye begins to progressively thin, causing it to bulge outwards in a cone-like fashion. This abnormality affects the patient’s vision since the light that enters the eye is no longer refracted properly onto the retina, which is responsible for converting the light into signals that are sent to the brain for interpretation.
If you have refractive eye errors that mean that you need to use prescription corrective eyewear to see clearly, and you suffer from a condition called keratoconus, you could be forgiven for thinking that you don’t have very many options available to you. In the past, patients who had keratoconus would only be considered suitable for glasses due to the nature of their condition. While glasses are extremely popular and effective, they also require patients to make some compromises – both in their appearance and in some cases, in the activities that they participate in. This is because it is impossible or impractical to wear glasses in some situations, such as when swimming, boxing and in cases where protective eyewear should be worn. Fortunately, the design of contact lenses has evolved and now there are varieties that enable people with keratoconus and other eye irregularities to benefit from using them. Here’s what you need to know about keratoconus and how scleral contacts can help.
