Collection of the wave front

The collection of the wave front presides over the conduct of a review aberrometrique. The optical quality of the eye is very correlated with the existence of phase shifts (optical path differences) within the wave front. Applications of wave-front collection mainly the study of Visual symptoms, suspected the origin to be optical. Surgery [...]
