What Is Laser Refractive Surgery?

Laser refractive surgery is a surgical technique in which a special cutting laser is used to redesign the shape of the cornea to correct problems of far-sightedness, myopia or astigmatism, which are collectively called refractive errors of vision.

In the normal vision, the cornea and the lens of the eye can focus light in proportion with the depth of the eyeball, meaning that light rays fall directly on the retina after going through the cornea and the lens.

Refractive Errors on the Retina

Refractive Errors on the retina which results in one or more of these problems are:

  • Nearsightedness (myopia): In this case, distant objects cannot be clearly seen, because light entering the eye is focusing in front of the retina and not on the retina itself.
  • Hyperopia (farsightedness): in hyperopia far objects can be seen better than near objects, but the vision is generally blurry, and this occurs when the lens cannot adjust its focusing power or when the eyeball is short in length.
  • Astigmatism: in astigmatism the eye has difficulty focusing light on one point in the retina, so that things appear blurry from all distances, and this problem usually accompanies nearsightedness or farsightedness.
  • Presbyopia is an age-related change in the lens structures, usually begins at the age of forty, when the lens of the eye loses its ability to adjust its convexity due to its increased rigidity.
