Torisoft contact lenses from CIBA Vision are designed for patients suffering from astigmatism. They are worn as daily wear lenses for up to a year and replaced. The double thin zone design of the Torisoft contact lens uses a lid-lens interaction to keep lenses properly oriented and the lenses are positioned under the eye lids easily and comfortably.
The lens material is 37.5% water and 62.5% tefilicon. The lens material, tefilcon, is a hydrophilic polymer of hydroxyethylmethacrylate.
