Is Astigmatism Causing Your Blurry Vision? (Ezine Ready)
Some of the sophisticated diagnostics used at Bellevue Lasik and Cornea in Seattle , Washington include: Visual acuity -- This is done through a phoropter, where the chin and forehead rest against the designated surfaces and you look through an aperture at the Snellen chart. The eye doctor or his assistant flips between different lenses, asking you to read the smallest line of letters you can see. This test measures your eyes’ refractive error and yields a corrective prescription for glasses or contacts. Keratometry -- A keratometer measures corneal curvature. A circle of light is focused on the cornea and its reflection is measured. This is a critical measurement in determining proper fit for contact lenses. Corneal topography, a more sophisticated procedure, may be used to gain greater details about the shape of the cornea. The measurements from these tests and others help your eye doctor determine if you have astigmatism, to what degree, and which treatment option will work best to help you achieve your best vision. Diagnosing and Treating Astigmatism Medical doctors do not know why astigmatism occurs. In some case it appears to be hereditary. In many cases it is present at birth but symptoms may not be obvious until early adulthood. Astigmatism can improve or worsen over time. To determine if astigmatism is contributing to your blurry vision, a visit to an experienced ophthalmologist is needed for a comprehensive eye examination. If astigmatism is diagnosed, treatment may be: Glasses or contact lenses to alter the way your eyes refract light. Laser vision correction, such as LASIK or any of its variants.Pages: 1 2 3 4 [5] 6
