When the cornea is affected by keratoconus, it begins to change shape from a sphere to a cone. This alters the vision, as light cannot pass through the cornea evenly when it takes on this new shape.
Keratoconus is thought to be a condition present from birth that is related to the collagen structure that gives the cornea its somewhat rigid shape. The most identifiable market of keratoconus is nearsightedness, which can only be corrected through hard or rigid contacts. Corneal transplant is a treatment option, but it is only necessary in rare cases of keratoconus.
