[Astigmatism and its treatments].
Astigmatism is a refractive error related to corneal asphericity. Congenital astigmatism is most frequent, and its correction with spectacles has been known for a long time. Contact lenses may sometimes be useful, but they may not allow a satisfactory visual correction. Anterior segment surgery (cataract, penetrating keratopasty, etc.) may often cause postoperative astigmatism. Improvement in ophthalmic surgery, and the patient's need for a rapid and effective visual recovery (as anatomical result is obtained), have highlighted prevention and treatment of post-surgical astigmatism. Astigmatism treatment is complex and varies according to its intensity and cause. Refractive surgery, modifying corneal shape, may be an elegant solution in cases where vision is low, in spite of a perfect corneal transparency.
