keratoconus-from our comments section

Keratoconus is a condition where the structure of the cornea loses its “stiffness”, and it begins to warp. This results in irregular astigmatism, which is difficult to correct with standard glasses and contact lenses. As the changes progress, the visual acuity decreases. If keratoconus develops at a young age (ie teenage years into the 20′s), the eye is more pliable, thus the changes are more dramatic. In later years, especially after 40, the structure is more rigid, so the condition is more stable. Fortunately, a new treatment called cross-linking has been developed recently that is of great benefit. Riboflavin and UV light are used to increase the links between the collagen fibers in the cornea. This reinforces the structure, and keeps it stable. So, age is a major factor as to how far the disease will progress, but technology is now allowing us to treat those that will evolve to the worse outcomes.
