The Custom Wave Contact Lens System


The Wave Contact Lens System is state-of-the-art technology 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 a “fingerprint”.
 

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.
