Low-light vision problems
In addition to those vision problems you've probably heard of before —
the lower order aberrations like nearsightedness and farsightedness —
there are common vision problems known as higher order aberrations
that can also affect your vision. Higher order aberrations are widely
believed by ophthalmic experts to contribute to common night vision
problems, including glare and halos.

Higher order aberrations cannot be corrected through traditional LASIK procedures. Similarly, glasses and contact lenses are unable
to help with these vision problems. An exciting new procedure,
called
CustomCornea®, is the first laser
vision procedure that's capable of correcting both lower order and
higher order aberrations.
Diagnosing higher order aberrations
Higher order aberrations are diagnosed and measured using wavefront
maps. These maps are plotted by passing a narrow ray of eye-safe
light through the optical system and measuring the optical
distortions as the light exits the eye. These patterns are then
compared with the flat wavefront associated with normal vision. An
ideal wavefront map would be perfectly flat.
