If you have astigmatism and wish you could wear contacts, we have good news for you. Contact lens technology continues to improve the wearability of lenses that provide correction for a variety of conditions, including astigmatism.
Astigmatism is an irregular shape of the cornea causing errors in light refraction. Some people think that astigmatism is a disease but it’s not. It is actually the most common refractive error because it can be associated with nearsightedness, farsightedness or exist on its own.
Most people who have astigmatism also have difficulty with near or distance vision. Because of the irregularity of the cornea in patients with astigmatism, finding the correct fit and comfort for a contact lens is more challenging. In the past, people with astigmatism were limited to gas permeable lenses, which are more rigid and, thus, even out the surface that light travels through to the eye. But not everyone finds gas permeable lenses comfortable enough for daily wear.
With the development of toric lenses, which are designed to fit the specific shape of each patient’s cornea, people with astigmatism are able to experience the comfort of soft lenses. These lenses continue to improve, and we are now fitting more patients with daily disposables. Many patients like the convenience of daily disposables, which require no cleaning. There is the added health benefit of lower risk of eye infections and discomfort, as each day starts with a fresh new lens. (Even the best cleaning regime can’t remove all the build-up on lenses.)
