Many patients with mild astigmatism have no symptoms from this and require no treatment. If there is regular astigmatism and it causes blurred vision, the astigmatism can be compensated for satisfactorily with eyeglasses or contact lenses. If myopia or hyperopia are also present, the glasses or contact lenses can also correct that condition. If the astigmatism is irregular or of a high degree, glasses or a soft contact lens may not fully correct the astigmatism and a hard contact lens may be necessary to allow the eye to see normally. Neither glasses nor contact lenses permanently correct the curvature abnormality. Modern refractive surgery, which reshapes the surface of the eye with a laser, can also be used to reduce or eliminate the astigmatism. Various considerations involving ocular health, refractive status, and lifestyle frequently determine whether one option may be better than another.
