s myopia, the laser makes the cornea flatter while in a hyperopic situation, the laser makes the cornea steeper. The problem does not come during the surgery but after it when the cornea bed reshapes itself to match the new cut cornea. They call it the cornea bed because it is just like a bed because as you lie on a mattress, it will reshape itself to the contour of your body. Once the cornea is made flatter, the cornea bed has no problem reshaping itself to the new contour; however, this is not always the case for hyperopia and astigmatism. The corneal bed, which is located behind the outer layer of the cornea, has trouble reshaping itself to either a steeper or narrower shape. Ophthalmologist do no fully understand why this occurs, but they do urge that LASIK provides better results for people who suffer from myopia and therefore, that is why the vast majority of people who undergo LASIK do so to correct nearsightedness (Buratto, 9).The results of LASIK are astounding (Gallo, 129). The obvious goal of LASIK is to get a vision of 20/20, which is perfect vision. 20/20, 20/40, and so on are measures of visual acuity; a person with 20/40 needs to stand twenty feet away from something that a person with 20/20 can see fine from forty feet away. Last March, the Journal of Ophthalmology stated that 3 months after the surgery, seventy-percent of the patients who have had LASIK, have 20/20 vision. A follow up 2 years after the surgery showed that sixty-three-percent kept the perfect vision while ninety-nine-percent had at least 20/40 vision. The amount of vision improvement generally is tied to the degree of nearsightedness and farsightedness before the surgery. Dr. Stephen Slade, who is one of the pioneers of LASIK said, The less nearsighted or farsighted you are, the more likely youll get 20/20. For low myopes, ninety-five percent can get 20/20. For high myopes, the figure might drop to sixty percent.Usually, for every good thing...
