Wavefront mapping system was first used in the field of astronomy. Every mirror made on earth has aberrations due to the gravitation. In order to get a clearer picture of the outer space of the solar system, the mirror of the telescopes should be compensated. Thus, wavefront mapping technology was first developed by astronomers, and it is used to adjust the optics of the telescopes.
With the same principal, custom wavefront mapping system is developed as an advanced guiding system that is widely used in eye laser surgery, such as Lasik. This mapping system is used to exam the type of your eye, for example nearsightedness or farsightedness, and so on. Then it is used to exam every little area of the eye to find low order aberrations and high order aberrations, then make sure which part of the eye should be cut and how much should be cut by laser, and finally the shape of your current eye shape and the shape it should be after eye surgery was drown by the system after a really complex mathematical calculations. With all this information done before the eye surgery, laser eye surgery can be done mostly under the guidance of computer.
There are three big manufacturers of custom wavefront mapping system in America. Their trade names are CustomCornea, CustomVue, and Zyopix, respectively. And their products are the Alcon LADARVision laser, the Visx S4 laser, and the Bausch & Lomb Technolas 217z laser, respectively. You can get more information about these products through internet.
As the eye is an extremely important part of human beings and it is very fragile, you should avoid any risk that may happen during the eye surgery. So, before you make decision, you should know every aspect of the eye surgery.
