Overview
The cornea is a thin, clear tissue that serves as the front wall of the eye and plays a critical role in transmitting light from the outside world into the eye. Several eye diseases can damage the clarity or shape of the cornea and prevent the uninterrupted passage of light through it.
Additionally, the cornea may play a role in a refractive error of the eye, resulting in an improperly focused image on the retina. Several surgical options are available for treating corneal diseases and correcting refractive errors.
