Corneal scarring refers to permanent opacities in the normally clear cornea. These marks can interfere with the passage of light and reduce visual quality.
Causes
Common causes include previous corneal ulcers, trauma, keratoconus, infections such as herpes simplex, and some types of eye surgery. The impact on vision depends on the size, depth, and location of the scar.
- Central scars affect vision more than peripheral ones
- Can cause glare, halos, or ghosting around lights
- May coexist with irregular astigmatism
Treatment options
Mild scarring may be managed with glasses or contact lenses to improve focus. More severe cases can require procedures such as phototherapeutic keratectomy or corneal transplantation, usually organised through general ophthalmology or corneal services.
