Astigmatism is a refractive eye condition that results in blurred vision. LASIK surgery can be a great solution for the blurred vision because the procedure treats the underlying cause of the condition rather than just improving the vision like glasses or contact lenses. “For people who are active and have Astigmatism, LASIK surgery can be very convenient because it eliminates the need to wear contacts or glasses.” People who develop Astigmatism have a cornea with an irregular curvature, like an oval shape, which is why blurred vision results. Since the cornea focuses light into the eye, the cornea of a person with Astigmatism doesn’t refract the light properly, thereby sending a skewed image to the retina, which in turn sends that image to the brain. LASIK surgery helps to fix this problem by reshaping the cornea so it becomes more spherical by removing small amounts of tissue that cause the cornea to be shaped irregularly through the use of a laser. The procedure is often quick and painless, with a short healing period.
