Rigid lenses correct astigmatism by creating a spherical service on the surface of the eye. A third option is Orthokeratology (Ortho-K) treatment. Patients wear Ortho-K rigid lenses for a period of time to reshape the cornea curvature. The correction will occur as long as treatment is ongoing.
What type of lens is used for astigmatism?

Conclusions: Toric IOLs reduce lifetime economic costs by reducing the need for glasses or contact lenses following cataract removal. These results can inform physicians and patients regarding the value of toric IOLs in the treatment of cataract and preexisting astigmatism.

This is true for moderate to severe astigmatism, since a survey of normal eyes shows that almost every human eye has a baseline corneal astigmatism of at least 0.25 to 0.50 diopters- in other words a small bit of mild astigmatism is very common and needs no treatment at all.
