Wavefront aberrometry for precise autorefraction

e-see’s core measurement technology, the patented PlenOptika Wavefront Refraction Engine™, offers eye care professionals and healthcare providers an unprecedented combination of clinical power and usability suited equally for the modern clinic, optical retail store, home visit, and global health mission. Peer reviewed research shows strong agreement in both prescription preference and resulting visual acuity between eyeglasses derived from subjective refraction versus those derived from wavefront aberrometry autorefraction.

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.

Anywhere Anytime Accurate Eye testing

With e-see, you can conduct autorefraction easily, anywhere—without compromising quality.
That means you can see more patients, and help them make the best vision care choices.
