- The cornea is normally clear transparent tissue in the eye, which allows light to pass and focus so that we can see. The cornea can become cloudy or opacified, due to the presence of scar tissue secondary to injury (or after eye surgery) or infection (e.g., Herpes infection of the
eye).
- Scar tissue prevents light from
passing through the cornea, resulting in loss of vision.
Scar tissue can be removed surgically or by use of the
excimer laser in a procedure known as phototherapeutic
keratectomy (PTK).
- In those with severe scarring and opacification of the cornea, a cornea transplant may be necessary.
