wavefront aberrometry technology

How wavefront works

Wavefront aberrometry is an advanced technique used in ophthalmology to measure how light through passes through the cornea and the crystalline lens, the refractive (light focusing) components of the eye. Distortions to the wavefront of light that occur as the wavefront of light travels through the eye are called aberrations, representing specific vision errors, and are captured with specialized optics called a Shack-Hartmann wavefront sensor. These specialized optical components are not typically found in traditional desktop autorefractors.

In the clinic, wavefront aberrometry technology can be used to precisely measure lower-order aberrations objectively ("autorefraction"), often with more accuracy with respect to subjective refraction than a traditional desktop autorefractor. Low-order aberrations can be corrected by spherical and cylindrical eyeglass lenses for nearsightedness, farsightedness, and astigmatism.
