Although LASIK eye surgery successfully corrected a high degree of nearsightedness, farsightedness and astigmatism, younger people with mild myopia and astigmatism is usually the best candidates for a good result.

Their expectations before the LASIK may also play an important role in how happy you are after. Remember, the goal of LASIK is to reduce your dependence on glasses and you look very well without glasses. The results vary from person to person.

Although many people who had LASIK they believe are better than they did with glasses or contact lenses before surgery, not all have the same experience. After LASIK, you can expect your vision a little better, about the same as with the glasses.

A small percentage of people may not notice their vision as good as it was before with glasses. But you should be able to drive safely and perform other routine daily tasks without glasses or contact lenses.
