For instance, keratoconus , an uncommon eye condition caused by a narrow, pyramid-shaped cornea, can contribute to severe astigmatism.

If you have severe astigmatism or keratoconus, your optometrist may recommend multiple treatment options, including corrective eyewear.

Your eye exam will start like most, with a quick discussion about your vision concerns and a vision test with an age-appropriate eye chart.

This test is done using different methods to evaluate how the eye focuses light. Firstly, your visual acuity will be measured, using a letter chart, to determine the clarity of your vision.
Then, the focusing power of your eye will be measured with a series of lenses placed in front of them. Finally, a Keratometer is used to measure the curvature of the cornea, while corneal topography can be used, if required, to provide an even more in-depth study of the surface of your eye.

There are three options to correct astigmatism — corrective spectacles, toric contact lenses, and refractive surgery.
Besides from refractive surgery, which can be very expensive, toric contact lenses are often the most convenient and effective option for correcting astigmatism. They differ from normal contact lenses in that instead of being spherical, they are actually a torus shape — more similar to a slice of a ring donut shape than a slice of a football shape. This allows them to bend and adjust to help your eyes focus on light effectively, therefore offering clearer and undistorted vision.
In most cases, other contact lenses contain one power all the way through the lens. In addition, toric contacts have a design that enables them to rotate into position so that the meridians of power are lined up with the meridians of your eyes that are in need of visual correction. Toric contact lenses are typically soft contact lenses , however toric editions of rigid gas permeable lenses can be used for correcting irregular astigmatism only.
Both glasses and toric contact lenses effectively correct astigmatism but generally contact lenses are preferred more. This is because they hold the shape of your eye and are considered more convenient to wear over glasses. As our eyelids loosening as we age, the pressure that the eyelids usually place on the cornea actually subsides, resulting in a decrease in the steepness of the vertical meridian curve.
In turn, the severity of the horizontal meridian curve is increased, resulting in a switch from direct to indirect astigmatism, which can worsen at a gradual rate itself.
Unfortunately, astigmatism cannot simply disappear. Sometimes direct astigmatism can lessen in severity, however can often go the other way and result in indirect astigmatism.
However, as stated above, you can correct your astigmatism with toric contact lenses, or can look for a permanent solution with refractive eye surgery. So, if you frequently experience any of these symptoms, please pay a visit to your eye doctor or go for an eye exam. Privacy Policy. Do not show me.
