LASIK is the correction of "lower order aberrations" which is exactly what glasses correct. Wavefront or Custom LASIK was developed to treat small imperfections in the vision but in reality mostly was helpful in reducing the creation of new aberrations that were a side effect of the laser treatment. These corrections were popular at first but didnt always fix the lower order aberrations as well and thus not as popular as was originally hoped. Wavefront optimized is the current state of the art for most people since this maintains the normal shape of the eye and induces few new aberrations while very effectively treating the lower order aberrations giving most patients the desired 20/20 result that they seek.

There are several laser platforms that provide this optimized custom treatment.  Some patients need a more customized treatment, and for these patients, a topography guided treatment or topo guided may be best.  This is because we only want to fix the aberrations which come from the cornea when we laser treat the cornea, and not those from other eye structures such as the lens.
