Astigmatism is an eye defect caused by the imperfect curvature of the cornea or the eye lens. Astigmatism due to irregularly shaped cornea is called corneal astigmatism, while irregular shape of the lens is called lenticular astigmatism. Symptoms of astigmatism are vision problems like near or farsightedness, blood shot eyes, crusty eyes, sensitivity of the eye and lump in the eye.
HOW IS ASTIGMATISM DIAGNOSED?
The ophthalmologist can diagnose Astigmatism with a comprehensive eye exam. Astigmatism may occur with other vision problems such as nearsightedness and farsightedness. The exam may include Visual acuity, Keratometry/Topography, Refraction, etc.
HOW IS ASTIGMATISM TREATED?
The treatment of this condition is conducted by an ophthalmologist who will prescribe corrective surgery. Also, procedures that can be used to install eyeglass lens so as to counteract the defective shape can be used.
