The customized procedure of LASIK, also known like WAVEFRONT LASIK or LASIK guided by wavefront, uses the three-dimensional measures of the eye to try it processes and them to guide the laser and to reform the cornea.

All the corneas are different, as a fingerprint and to be able to establish these differences must take a special examination from the eye, the aberrometría or corneal Wavefront.

This diagnostic examination the optical aberrations produced by the small deformities in the curvature of the cornea, that are responsible for 15% of the refracting defect. (The other 85% are due to the defocusing produced by the myopia, hipermetropía or the astigmatism). These optical aberrations are the people in charge of annoying visual symptoms such as the ghost sparkles, or images around the lights at night and that makes see, for example, the traffic lights with some images around or to see defocused stars. This measurement system allows the profit of results of correction of vision extremely precise and individualized or customized (the correction with wavefront considers these small differences and when being used, the correction that is reached gives incomparable a visual quality), effects that would be impossible with the conventional surgery of LASIK.
