Traditional eye exams used in Lasik operations can single detect two corneal abnormalities, these man cylindrical and spherical. A cylindrical abnormality results in astigmatism, while a spherical abnormality results in myopia and hyperopia (near sightedness and farsightedness).

Wavefront technology, on the other hand, can detect an infinite number of aberration. It accomplishes this by using a fixation target along near an input laser beam. The laser shaft generates a buoyant source, which is a wavefront sensor that is used to calculate the slope of the wavefront as it exits. The software then determines the excimer ablation’s characteristics.

So, if you suspect you own eye problems other than astigmatism, nearsightedness or farsightedness, Wavefron is worth the extra cost.
