Corneal abrasions can cause astigmatism

Corneal abrasions can cause astigmatism depending on the specific condition.

Astigmatism refers to parallel light rays entering the eye can not form a focus, but produce two focal lines, resulting in unclear imaging on the retina. Because the cornea is an important part of the eye refractive system, some patients will cause refractive power changes after severe corneal abrasions, thus affecting light refraction, and astigmatism may occur. However, if corneal abrasions are mild, they usually do not cause astigmatism.

Patients usually need to pay attention to eye protection and use their eyes reasonably.
