The Wave Contact Lens System
capable of designing custom contact lenses
. No two fingerprints are identical
and the same is true for your eyes, especially the cornea (the clear tissue that
a contact lens sits upon). Each cornea has its own shape or topography just like
The Scout Keratron is used by the Wave System to
determine the exact curvature of your cornea. This instrument photographs the
cornea while projecting a series of concentric rings on the corneal surface. Thousands of these data points are analyzed to create a
topographical map of the cornea, capturing any variations that may be
present. In the normal cornea this irregularity may reflect only the
presence of astigmatism. Astigmatism is present in most eyes because the cornea
is not totally spherical like the surface of a basketball, but rather shaped
somewhat like a football.
The rings that are projected onto your cornea contain thousands of data
points. These rings are then converted into a
topographical map that undergoes further analysis.
An example of the topographical map that illustrates a small
amount of normal astigmatism (the oblique bowtie configuration).
