Hyperopia also known as farsightedness is a condition in which a person has difficulty focusing on close objects. The eye is shorter than normal; the light rays diverge before reaching the retina, and are therefore out of focus on the retina. Nearby objects can appear blurry, while distant objects are clearer. Very farsighted patients may report that they are unable to focus on objects at any distance.
This condition can be treated with LASIK surgery. LASIK surgery works by reshaping the surface of the cornea, enabling it to better focus light. The surgeon cuts a flap into the epithelium, the outer layer of the cornea. Tissue underneath is removed, or ablated with an excimer laser. The goal in farsighted people is to create more of a slope in the cornea, making it easier to focus light on the retina.
