LASIK is a treatment that corrects refractive errors. This eye surgery reshapes the cornea, making clearer vision possible. Refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism hinder a person’s focusing ability of the eye, thus making them dependent on eyeglasses and contact lenses. LASIK provides patients with an alternative. This safe and effective procedure removes a predetermined amount of corneal tissue and reshapes the cornea, which improves the focusing power of the eye and visual acuity. LASIK helps to reduce a patient’s reliance on eyeglasses and contact lenses.
