lasik laser surgery
Since higher order aberrations are entirely unique to a particular patient, much like fingerprints, a wavefront analysis system (known as an Aberrometer) is used to measure these aberrations. The Aberrometer is digitally interfaced with a sophisticated, computer controlled laser, which is directed in a precise manner over the cornea. In essence, the laser custom sculpts the cornea – a completely customized reshaping of the corneal surface.
The procedure employed by the wavefront analyzer to measure higher order aberrations would appear quite complex to a layman.
