Custom wavefront is a tried and try technology that has many applications aside from mapping the human eye.
This is the same technology that has been used for years by astronomers to adjust the optics of their telescopes.
Because of the gravitational pull of earth when a mirror is made, there are always aberrations that are incorporated into every mirror made on earth.
To view the outer reaches of the solar system, astronomers had to develop a way to compensated for this and map their mirrors so a clearer picture could be seen.
This is the same thing that must be done to both eyes of every patient.
The reason is that there are no two eyes exactly the same.
The procedure involves the mapping of every little area of the eye to catch every aberration must be not only located but type determined.
There are low order aberrations and high order aberrations.
The low order aberrations include the spherical shape of the eye and the cylinder shape of the eye.
This is more commonly known as near-sidedness and far-sidedness.
The high order aberrations are too many to name but are all mathematical calculations like the Zemike polynomials which represent the first eight levels of these aberrations.
In America there are three different manufacturers of this technology.
Their trade names are CustomCornea with an Alcon LADARVision laser, CustomVue with a Visx S4 laser and Zyopix with the Bausch & Lomb Technolas 217z laser.
Once you have decided on a clinic and know which laser unit they use for their custom wavefront procedure, as the patient you should read up on it so you know the risks involved.
Your eyesight should not be something that is taken for granted.
