Keratoconus is a progressive eye disorder in which the normally round, dome-shaped cornea gradually thins and bulges outward into an irregular cone shape, distorting light entering the eye. This structural change causes increasingly blurred and distorted vision that becomes difficult to fully correct with standard eyeglasses as the disease advances. It typically begins during the teenage years or early adulthood and can progress over one to two decades before often stabilizing. The exact underlying cause is not fully understood, though genetic predisposition and chronic eye rubbing are strongly linked to its onset and progression.

What are the main symptoms of Keratoconus?

The most common symptoms include: progressively blurred or distorted vision; increased sensitivity to light and glare; frequent changes in eyeglass prescription; difficulty seeing at night. Early recognition is key to prompt diagnosis and effective treatment.

Is Keratoconus contagious?

No, Keratoconus is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

How is Keratoconus treated?

Treatment options include: In early stages; glasses or soft contact lenses correct vision adequately; while rigid gas-permeable or scleral contact lenses are often needed as the cornea becomes more irregular. Corneal collagen cross-linking. Treatment should always be guided by a qualified Ophthalmology specialist. Do not self-medicate.

Can Keratoconus be prevented?

While Keratoconus cannot always be fully prevented, several measures can reduce risk: avoiding vigorous eye rubbing; treating underlying allergic eye conditions promptly; regular eye exams to detect early corneal changes.

When should I see a doctor for Keratoconus?

Consult a Ophthalmology specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
