Surgery Laser for the View

The cornea is a part of the eye that helps to the light to be focused to create an image in the retina. It works very seemed like the lens of a camera focusing the light to create an image in the movie. This inflection and focus of light is known like refraction. Frequently the form of the cornea and the eye are not perfect and the image in the retina is blurry (out of focus) or themselves tuerce.the defects of the power of focus of the eye are called the refractive errors. There are three primary types of refractive errors: myopia, hyperopia and the astigmatism. The people that suffers from myopia has more difficulty in seeing objects to the distance so clearly as to the objects closely. The people with the hyperopia has more difficulty in seeing closely the objects so clearly as to the distant objects. The astigmatism is a distortion of the image in the retina caused by irregularities in the cornea or the lens of the eye. The combinations of the myopia, the hyperopia and the astigmatism are very common. The eyeglasses or the contact lenses are designed to balance the imperfections of the eye. The surgical procedures directed to the improvement of the power of focus of the eye are called refractive surgery. In the surgery laser for the view, the exact retreat and controlled of the fine weaving of the cornea by a special laser forms again the cornea that changes their power of focus and that corrects the refractive errors of which the person suffers.
