At Eyes on Henry, we often find patients with astigmatism along with nearsightedness or farsightedness. This condition is due to a misshaping of the cornea or lens of the eye and can cause patients to have a hard time focusing at any distance. It's one of the most common eye conditions we see, and one of the easiest to treat.
For healthy eyes without astigmatism, light passes through the lens and focuses on the retina to transmit images we see and signals the brain. For patients with astigmatism, the cornea or lens are not normally curved and instead are shaped more like an oval, rather than a circle. This means that some of the light rays will fall short of their focus point, and light cannot reach the retina as clearly, causing pictures to be blurry instead of sharp.
While most people with astigmatism are born with it, some can develop it due to an accident, eye injury or eye surgery.
Astigmatism can also occur due to a rare condition call keratoconus. With this condition, the cornea of the eye becomes thinner and thinner, causing it to develop a cone shape. This usually causes a severe amount of astigmatism that even eyeglasses can't help support with vision. Special contact lenses are usually the best option for patients with keratoconus.
The eye doctors at Eyes on Henry offer multiple options for dealing with your astigmatism. The best method for you depends on the degree of correction your eyes need, along with your lifestyle.
Most patients opt for eyeglasses to correct their vision. We offer glasses with a special cylindrical lens that can compensate for the shape of your eyes. These lenses provide different prescription powers in different parts of the lens.
If you'd rather wear contact lenses instead of eyeglasses, we offer toric lenses to correct your eyesight. They can correct for many types of astigmatism. We also provide rigid gas permeable lenses as another option. Because of the wide variety of focus problems with astigmatism, fitting contact lenses correctly will often take more than one try, but for most patients, we can find the right type of lens for their eye.
