What is Custom LASIK?

Custom LASIK uses a technology called "wavefront" to diagnose the unique shape of the patient's cornea, then to create a map that the surgeon can use to perform very precise LASIK adjustments. The wavefront technology has been around for decades, used by astronomers to adjust the large mirrors in their telescopes to correct for distortions caused by the earth's atmosphere. Only recently has it been applied to the improvement of human vision. Many surgeons will perform a wavefront diagnostic for all patients requesting vision correction surgery. Not all will use this diagnostic to create the surgical map, either because they do not find it necessary or because the diagnostic shows the patient is not a good candidate for laser surgery.
