Corneal cross-linking uses eye drops and UV light to strengthen the cornea’s collagen fibers. It usually stops the cornea

Corneal dystrophies are rare diseases that run in families and progress slowly over many years. With corneal dystrophies, abnormal material builds up in the cornea. This can cause blurred vision or even loss of vision. Corneal dystrophies may be treated with eye drops, ointments or special contact lenses.

A corneal laceration is a cut on the cornea. They are usually caused by something sharp flying into the eye. A corneal laceration needs to be treated right away to avoid vision loss.
