What is Keratoconus?

Keratoconus is a progressive eye condition where the cornea thins and bulges into a cone shape, distorting vision. It typically starts in adolescence or early adulthood and can worsen over time. Key facts: it affects about 1 in 2,000 people, is not contagious, and early diagnosis is crucial to prevent severe vision loss. Treatments like corneal cross-linking (CXL) can halt progression, while advanced cases may require ICL implants or corneal transplant.
