LASIK is an eye surgery done to correct a patient's dependency on wearing contact lenses or eyeglasses. This surgery is most common in patients that have nearsightedness, farsightedness, or astigmatism. There are a few different types of LASIK surgery to be performed. Which one is used depends on the patient and that particular patient's problem. The first step towards having this procedure done is to talk with your Ophthalmologist to see if you are a good candidate.
