Astigmatism Correction with Toric Contact Lenses
|Toric contact lenses are quickly gaining in popularity with people who have astigmatism. While popularity continues to grow, recent studies show 4 in 10 astigmatics are unaware they can wear contact lenses. Fortunately, advancements in contact lens technology now allow virtually any person with astigmatism to wear contacts.
Astigmatism is most often caused by a misshaped cornea, or corneal astigmatism, and can also be caused by a misshaped lens behind the cornea, called lenticular astigmatism. Commonly called "A Stigmatism" in the doctor's office, astigmatism can now be corrected with toric contact lenses, eyeglasses, or surgery.
Toric contacts have two different powers to correct for both the astigmatism itself and for the near or far-sightedness in the eye. It's not uncommon for someone to have astigmatism in one eye. In these cases, your eye doctor can prescribe an astigmatism contact lens for one eye and an ordinary spherical lens for the other eye.
Torics can come in soft or rigid gas permeable. Unlike a spherical lens though, toric lenses have a definite up and down position due to the nature of the astigmatism.
Cooper Vision, Bausch & Lomb, Ciba Vision, and Johnson & Johnson VisionCare, Inc. all make toric contacts. Soflens 66 Toric and Purevision Toric have been around while newcomers such as Acuvue Oasys for Astigmatism and Proclear Toric are starting to gain market share.
