Refractive errors are disorders, not diseases. Light has to be refracted or bent by the cornea and the lens to the retina in order for us to see. The eye may not bend light correctly which will cause vision to be blurred. The common refractive disorders are described below.
Myopia (distant objects are blurry)
ICL corrects higher degree of refractive error which cannot be done by laser treatments. Implantable contact lenses (ICL spherical /Toric) is surgically implanted in the eye between the iris and the natural crystalline lens through a small corneal incision.
Hyperopia (close objects are blurry)
Also known as farsightedness is usually inherited. Children are often hyperopic which may lessen as an adult.
Presbyopia (aging of the lens in the eye)
After age 40, the lens of the eye becomes more rigid and does not flex as easily. The result is that it is more difficult to read at close range. This normal aging process of the lens can also be combined with myopia, hyperopia or astigmatism.
Astigmatism (blurred vision at all distances)
Astigmatism usually occurs when the front surface of the eye, the cornea, has an irregular curvature. Normally the cornea is smooth and equally curved in all directions and light entering the cornea is focused equally on all planes, or in all directions. In astigmatism, the front surface of the cornea is curved more in one direction than in the other. This abnormality may result in vision that is much like looking into a distorted, wavy mirror. Usually, astigmatism causes blurred vision at all distances.
Difficulty reading or seeing up close
Crossing of the eyes in children (esotropia)
Refractive disorders are commonly treated using corrective lenses, such as eyeglasses or contact lenses. Refractive surgery can also be used to correct some refractive disorders.
