The cornea is the outer surface of the eye. In normal vision, light rays first pass through the cornea and are directed through the pupil. The light is then focused by the lens so that a sharp image is projected onto the retina. With astigmatism, the curvature of the cornea is irregular. The lack of uniform curvature creates a random, inconsistent focus pattern, especially when combined with near-sightedness or far-sightedness.
Ocala Eye ophthalmologists can correct astigmatism in several ways. Two of the most common are limbal relaxing incisions (LRIs) and the use of CustomVue LASIK.
