What is keratoconus?

Keratoconus is characterized by the thinning and bulging of the cornea, which causes it to form a cone-like shape. This alteration in the cornea's structure leads to various visual distortions and can significantly affect a person's vision. The irregular curvature of the cornea prevents light from being focused properly on the retina, often resulting in blurred or distorted vision. This condition typically begins in the teenage years or early twenties and can progress over time, requiring various interventions, such as glasses, contact lenses, or even surgical procedures for management. This definitive description aligns perfectly with the characteristics of keratoconus, thus making it the correct choice.
