Hyperopia, or far-sightedness, is the opposite of myopia, or near-sightedness. It is a change in vision caused by the displacement of the point of focus, causing images to lose their sharpness when viewed close up. In these cases, the images form behind the retina.
The two main reasons for far-sightedness are that the diameter of the eye is too short, or the refractive power of the lens or cornea is too weak. In most people, hyperopia is a genetically inherited trait that presents in childhood, often with headaches.
Hyperopia can be currently corrected with glasses or contact lenses, or through intraocular surgery. These different treatment modalities are adapted to different types of patients and to different types of refractive errors. However, in most people, the method that provides greater satisfaction, with more comfort and visual freedom, is laser correction surgery.
