Why is corneal thickness important when considering LASIK?

The thickness of the cornea is one of the major factors in determining if LASIK is the most appropriate refractive surgery for an individual.  During LASIK a flap is cut on the surface of the cornea.  The flap is peeled back, and a laser reshapes the cornea by removing tissue before the flap is laid back down.  The amount of tissue removed is determined by the prescription power being corrected, thus someone who is more myopic would require more tissue removed.  A certain amount of corneal bed thickness must be maintained to prevent an increased risk of post-surgery complications such as corneal ectasia.  However, just because one doctor feels a patient has corneas that are too thin to safely undergo LASIK does not mean that would be the consensus among all doctors.  Experienced surgeons using advanced equipment might be able to perform LASIK on a patient who was denied by another physician.  And conversely, one doctor might recommend LASIK where another would not.  For this reason, it is important to visit a reputable doctor, and in some cases, seek several opinions before proceeding with a refractive surgery.
