Keratoconus is a progressive eye condition characterized by the thinning and bulging of the cornea into a cone shape, which leads to distorted and blurred vision. It typically manifests in late adolescence or early adulthood and can worsen over time, resulting in increased sensitivity to light, glare, and difficulty seeing at night. While the exact cause is not fully understood, genetic and environmental factors may contribute.
Treatment options depend on the severity of the condition and can include glasses, rigid gas-permeable contact lenses, and corneal cross-linking to strengthen the cornea. Scleral lenses are particularly beneficial for individuals with keratoconus, as they provide a stable fit and create a tear-filled reservoir over the cornea, improving comfort and visual acuity. In more advanced cases, corneal transplants may be necessary. Regular monitoring by an eye care professional is essential for effective management of keratoconus.
