 Your
eye and vision are like your fingerprint-truly distinctive
and personal. They are distinctive because light is
scattered unevenly to form a pattern that is unique
to your eye and because your cornea has a unique shape.
Each Zyoptix treatment assessment involves an extra
diagnostic (screening) process extensive enough to let
the surgeon to let the surgeon see every individuals
patient’s unique optical characteristics.
How
Zyoptix Works
Zyoptix software combines data from two different types
of diagnostic equipment ,then programmes the laser with
your unique treatment , based on this data. Data is
collected to assess the structure of your cornea (Called
topography). Data is also collected from a measurement
of your optical system using the advanced wavefront
technology, a measurement not normally taken with standard
LASIK treatments. The next section will explain how
topography and wavefront work together to ensure the
most thorough screening and treatment programme.
The
wavefront factor: measuring your vision
Wavefront was first developed by astrophysicists and
has now been applied to Zyoptix. It provides the most
technologically advanced measurement not just of standard
visual but also of scattered light errors Known as ‘aberrations.’
Wavefront technology or aberrometry is based on the
principle that if an eye had no imperfections at all,
light passed through it would not scatter. But because
no eye is perfect, light scatter to form distinct patterns-
called a wavefront. Wavefront technology Measures your
eye’s optical system enabling the surgeon to plan
a treatment that exactly matches individuals vision
errors.
Wavefront Aberration
3 dimensional view
Your wavefront will be measured by the market –
leading aberrometer, the Zywave™ From . The Zywave aberrometer measure the eye from the
center to the outer edges (the periphery) of the pupil.
This is especially important, because at night your
pupils open up and more light is scattered in the periphery
of the pupils. Your surgeon needs to know as much about
your night-time as your day-time vision.

topography: assessing your corneal surface
While it is important that your surgeon measures your
optical system, it is equally important to know the
shape of your cornea. This screening test enables the
surgeon to assess the general health and thickness of
your cornea and so to determine if you are suitable
for laser eye treatment.
The Zyoptix system collects this information form over
9,000 points across the cornea, using Orbscan® llz market-leading topographer.
