When a ray of light first enters the eye, it passes through the cornea to the lens and vitreous, ultimately reaching the retina. As it bounces off the retina and returns back through the cornea, the wavefront analysis detects and documents these distortions, which are unique to each individual. Because each patient has a unique visual optical system, the wavefront data has been likened to a fingerprint.
