Astigmatism is due to an irregularity of the corneal curvature resulting in blurred vision at all distances. It is corrected by spectacles or contact lenses with a cylindrical (toric) lens.
Toric lens implants are used for patients with significant astigmatism, who require glasses for both distance and near vision. Toric lens implants can achieve good distance vision without the need for glasses. I use lenses from Abbott and Alcon.
