Contact Lens for Astigmatism

Astigmatism is a very common vision problem that occurs when the cornea is more oval than round. Astigmatism can be corrected by glasses or contacts.

Soft Toric Contact Lenses vs. Rigid Gas Permeable (RGP):Either a soft toric lens or a rigid gas permeable lens can be used to correct astigmatism. Toric soft contact lenses must remain stable on the eye to produce good vision. If there is too much rotation of a toric soft contact lens, a patient will not have clear vision. Toric soft contact lenses are available in both hydrogel and silicone hydrogel material. There are also multifocal toric lenses available which correct both astigmatism and presbyopia (normal aging process in which a patient’s near vision becomes blurry).

For patients with a high amount of astigmatism, an RGP lens may be a better option.

An RGP lens will provide crisper vision. It is made of a stiffer material. RGP lenses are less comfortable initially than a soft lenses and do take some time to adjust to. Your eye care professional can decide which lens choice is the best for your astigmatism.
