Utilizing a proprietary, non Hartmann-Shack technology (patents pending) the Z-View Aberrometer quickly and accurately measures high order aberrations (3rd-6th order), as well as sphere, cylinder and axis to arrive at a fully optimized prescription in less than a minute. This compact, flexible instrument performs like a high-end surgical aberrometer, but at a fraction of the cost.* Your patients will receive a highly customized wavefront guided prescription, and you will have more quality time to spend with them.

The small footprint fits easily into the dispensing practice, and provides objective wavefront measurements via through-the-lens optics, virtually eliminating instrument myopia.

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 world 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 Ophthonix Z-View Aberrometer measures the shape of these waves with a proprietary wavefront sensor. The deviations of these waves from perfect are then analyzed with Ophthonix's proprietary computer algorithms and converted into the patient's prescription.
