Can astigmatism go away on its own?
No. About 30% of all people have astigmatism. In the vast majority of those, the condition does not change much after the age of 25. The presence of astigmatism as a child or young adult does not signify that an eye disease will later occur. Progressive astigmatism can occur with corneal trauma, repeated infections of the cornea, and degenerative diseases such as keratoconus.
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 (rigid) 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. Wavefront guided LASIK or photorefractive keratectomy (PRK) can also reduce irregular astigmatism. Various considerations involving ocular health, refractive status, and lifestyle frequently determine whether one option may be better than another.
