The Z-View™ Aberrometer is based on the theory of wavefront measurements. If the cornea and lens of a patient's eye were perfect, a matching set of plane waves entering the eye would focus onto a very small spot on the retina.

However, in actual human eyes the waves are distorted causing a slight blur on the retina. Although this is sub-optimal, it is 20/20 vision. Conversely, in the perfect eye, light from a single point on the retina would form a perfect set of plane waves leaving the eye. The Z-View™ Aberrometer measures the shape of these waves with a proprietary wavefront sensor. The deviations of these waves from normal are then analysed with Ophthonix's proprietary computer algorithms and converted into your HIGH DEFINITION prescription.
