Wavefront: A Text and Atlas will give a personal light to the readers. Personal because it is showing personal experiences of refractive surgeons, clinical activity, and also, because it is showing a “panorama” or wavefront and aberrations “planet” without preconcepts, but based on elementary opinions, descriptions and cases.
To the reader the final judge, hopefully uncontaminated.

11Preface
In our daily activity, the ophthalmologists as well as the optometrists have dealt with refractive errors—myopia, hyperopia, presbyopia, and various forms and combinations of astigmatisms. In terms of eye aberrations, they are part of the lower-order aberrations precisely of the second-order. Lower eye aberrations include piston tilt/prisms which are zero- and first-order, and together with the second-order are estimated to form 80/85% of all eye aberrations.
The second leg of this topic—the higher-order aberrations, have come into frequent use, and with the advent of and consolidation of refractive surgery, together with the commercialization of aberrometers. Further knowledge and insight into these aberrations has been attained.
However, aberrations are newcomer in our language and practice. The effort herein, which is quite elementary seeks to deal with and offer a handy consultation atlas, simple to read and easier to consult in our offices. While lower-order aberrations are manageable with spectacle glasses, contact lenses and refractive surgery. Higher-order aberrations though quite known and understood still have treatment far from offhand.
In the atlas, the readers will find a fluent descriptive part, some clinical examples and cases. At the end of all, a few graphical elaborations and clinical pictures retrieved from present and updated literature. The topic is in full debate and evolution. My desire was that simple—provide a manual and I hope that I have met the task.
