Wavefront Technology
(Aberrometry):
Aberrometry measures the way
a wavefront of light passes
through various refractive
or focusing components of
the eye, such as the eye's
clear front surface (cornea)
and crystalline lens.
Different distortions that
occur as light travels
through the eye are known as
monochromatic aberrations,
representing specific vision
errors.
Wavefront technology, or
aberrometry, diagnoses both
lower- and higher-order
vision errors represented by
the way the eye refracts or
focuses light. Higher-order
aberrations are more complex
vision errors, whereas
lower-order aberrations are
more common vision errors
such as nearsightedness,
farsightedness, and
astigmatism.
