Wavefront or custom lasik makes use of a laser to reshape the cornea in order to improve your eyesight. The term wavefront lasik comes from the sensor that is used to make a three dimensional map of your eye. The wavefront laser will not damage the eye, but it does provide an accurate map of how the retina reflects light. With this information, your lasik doctor can determine what type of reshaping will improve your vision.
For those of us that have worn glasses, it is easy to understand the need to have better vision. Clearly, with the advances in lasik, including wavefront lasik, the benefits of such a surgery can have lasting positive effects through your life. Once the wavefront lasik surgery is complete, you may not need to fumble with contacts or glasses in order to have perfect vision, in most cases. As a result of the advances in custom lasik technology, there is a good chance the outcome of the surgery will be known well before the actual surgery takes place.
Basically there are three eye surgery methods. All of them are called almost the same: LASIK, LASEK and LASAK. Those methods can be combined with two other treatments to give a better result. Those two methods are: Wavefront treatment and Aspheric treatment.
