Corneal scarring occurs when the clear front surface of the eye, known as the cornea, becomes damaged and develops opaque areas. This can result from various factors, including infections, injuries, or conditions like keratitis. The scarring can affect vision by obstructing light as it enters the eye. Symptoms of corneal scarring may include blurred vision, sensitivity to light, and discomfort. Treatment options vary depending on the severity and cause of the scarring, ranging from medications to surgical procedures, such as corneal transplantation, to restore clear vision.
