A LASIK treatment is the correction of refractive errors such as myopia, hyperopia and astigmatism with an excimer laser. This method is also known as “eye cutting”. Myopia means near-sightedness and hyperopia long-sightedness. Astigmatism, on the other hand, is a crooked and distorted view, because the light shining on the eye, falls on several points of the retina. Astigmatism can result from the cornea (the translucent layer in front of the colored area of the eye) or the eye lens. During eye laser surgery, the cornea is reshaped with the laser in order to correct refractive errors such as myopia, hyperopia and astigmatism.
