Cornea and External Eye Disease
Cornea and external eye diseases affect the front surface of the eye, impacting vision, comfort, and eye health. Early diagnosis and appropriate treatment are essential to manage symptoms, prevent complications, and maintain clear, stable vision over time.
Understanding the Cornea and External Eye
The cornea is the clear, curved front surface of the eye that plays a key role in focusing light. Along with the surrounding external structures — including the eyelids, conjunctiva, and tear film — it helps protect the eye and maintain clear vision.
Because these structures are directly exposed to the environment, they are more susceptible to irritation, infection, and injury. Even minor changes can affect comfort, clarity, and overall eye health.
The cornea is the clear front window representing one-sixth of the outer layer of your eye. The primary function of the cornea is to focus and transmit light onto the retina.

Keratoconus
A condition where the cornea thins and changes shape, causing distorted vision and requiring ongoing monitoring and care.
