What is Understanding Myopia and Hyperopia about?
Myopia, or nearsightedness, results when light rays focus in front of the retina due to a cornea with too much curvature or an eye that is too long. Laser treatment for myopia flattens the cornea to lessen its focusing power and allow light to focus on the retina. Hyperopia, or farsightedness, is caused by a cornea that is too flat or an eye that is too short, focusing light behind the retina. Laser treatment for hyperopia steepens the cornea to increase focusing power and focus light on the retina. Astigma
