Corneal Opacity |
| The cornea is normally clear; however, it can become cloudy, or opacified, due to the presence of scar tissue, an injury, or infection. Scar tissue prevents light from passing through the cornea resulting in vision loss. Scar tissue can be removed surgically, or by use of the excimer laser in a procedure known as phototherapeutic keratectomy (PTK). When the scar tissue or opacification extends deeper into the corneal tissue, a cornea transplant may be necessary. |
