What Is Keratoconus?

Keratoconus is an eye condition in which the cornea, the clear front surface of the eye, gradually becomes thinner and changes shape. This can cause irregular astigmatism, blurred vision, glare, and difficulty seeing clearly. Early diagnosis and appropriate monitoring are important for protecting long-term vision.
