Keratoconus is an inherited condition causing the clear window at the front of the eye, the cornea, to become distorted and irregular, causing myopia (nearsightedness) and astigmatism. Often one eye is more affected than the other. Accurate mapping of the cornea is recommended to detect and monitor progression of keratoconus.
In the early stages of keratoconus spectacles can improve vision. Vision may become unsatisfactory with spectacles; therefore specialized contact lenses will be required. In advanced keratoconus the thinned cornea is weaker and more susceptible to damage from minor trauma. Recent advances in technology mean some individuals may benefit from collagen cross-linking, a procedure to reinforce the cellular bonds within the cornea to prevent further distortion. Occasionally a cornea may become cloudy from scarring or too irregular to allow useful vision and a corneal transplant is necessary.
Regular visits to your Optometrist are recommended to ensure vision is optimized.
