"Keratoconus" Natural Recordings by Native Speakers
Keratoconus is a rare eye disorder characterized by a progressive thinning and bulging of the cornea, the clear dome-shaped surface at the front of the eye. This causes the shape of the cornea to change from its typical round shape to a cone-like shape, leading to blurry or distorted vision, as well as sensitivity to light. Keratoconus often begins in the teen years and may worsen over time if left untreated. Treatment options may include glasses, contact lenses, corneal cross-linking, and surgical implantation of a clear lens to correct the shape of the cornea.
