Keratoconus, illustration 插畫檔

Illustration of a normal eye (left) and an eye affected with keratoconus (right). This is an eye condition where the cornea gradually thins and bulges outward into a cone shape. This irregular shape prevents light from focusing correctly on the retina, leading to distorted and blurred vision. Mild to moderate keratoconus can be treated with eyeglasses or contact lenses. Advanced cases can be treated with corneal grafts
