There are significant differences between wavefront-guided LASIK and conventional LASIK. First, there is a difference in the way the eye is measured. Wavefront-guided LASIK uses a wavefront scanner to measure the passage of light from the front surface of the eye to the back, creating a unique wavefront map for each eye. Second, the laser treatment is more precise, removing more of the aberrations that cause glare and halos. The data shows that wavefront-guided LASIK outcomes are better than conventional LASIK with a higher percentage of patients achieving 20/20 vision or better.
