Regular eye appointments are very important to make sure contact lenses fit properly and continue to correct vision. Because the eye’s shape is changing over time, these may not fully correct the problem in the later stages, but rigid gas permeable lenses can still produce significant improvements.
While there are no medications that can prevent keratoconus from progressing, its effects on vision are correctable with glasses or contact lenses in the early stages.
#The vision disorder due to a misshapen cornea is crack
When a crack forms, the cornea will swell, significantly impacting vision for weeks or months as it heals, leaving a scar behind that also impacts vision. In rare cases, the thinned cornea may develop a tiny crack because of the strain of the cone-like shape. As keratoconus worsens, it can produce double vision, multiple images, glare around lights, and poor night vision. Typically these symptoms will appear in the late teens or 20s, and may progress for up to twenty years before slowing. In early stages, keratoconus results in slightly blurred and distorted vision, as well as sensitivity to light and glare. With keratoconus, because of the misshapen cornea, the image reflected through the lens of the eye becomes distorted at any distance, producing multiple images or warping them before they reach the retina. This makes the image reflected through the lens fall in front of the retina or behind it, making images blurry at different distances. The reason many people need glasses at an early age is that their eyes are too long or too short. The different structures of our eyes need to have very specific shapes in order to reflect light onto the light-sensitive retina and enable us to see clearly. That pointed cone shape of the eye in such scenes isn’t much different from the effects of keratoconus, a vision disorder in which the cornea (the front part of the eye) goes from being its normal rounded shape to thinner and more pointed.
