Keratoconus is a progressive eye condition in which the cornea — the clear front surface of the eye — becomes thin and gradually bulges outward into a cone-like shape. This change in shape prevents light from focusing properly on the retina, causing blurred and distorted vision.

The condition usually begins during the teenage years or early adulthood and may progress slowly over time. Many people may not notice symptoms in the early stages, which is why regular eye examinations are important for early detection.

Common symptoms include blurred vision, sensitivity to light, frequent changes in glasses prescription, and difficulty seeing at night. With proper diagnosis and monitoring, keratoconus can be managed effectively, and most patients can maintain clear and comfortable vision.

Early diagnosis is the key to protecting your eyesight and preventing disease progression.
