This review of wavefront technology looks at 2 aspects. The first is the basics and principles of the optics of the eye, how to decompose the wavefront in a more adequate way for interpretation and how these aberrations affect the visual acuity. It addresses the diversity and complexity of wavefront sensors; how these devices transform the principles into clinically useful data, with the advantages and limitations of each system. The second major aspect is the clinical uses of the technology: wavefront-guided and newer and enhanced profiles related to wavefront as well as the limitations of the technology. Recent innovations made possible by wavefront technology that are not limited to refractive surgery are reviewed.
