Epithelial thickness mapping is one of the latest technologies that can assist with determining candidacy. What’s exciting about this technology is that we can now look at the thin layer of cells on the surface of the cornea and determine if there is a potential problem in the future for someone. Even more exciting though is that it allows us to look at an even finer detail than ever before meaning that some people who had been told they might not be a candidate may now that we have even better information. Many LASIK practices do not have access to this technology, but we feel it should be standard!
