I have used various autorefractors in my career, many have provided a good starting point for subjective refraction. However, with the OPD-Scan III and TRS-5100, I now have the accuracy of wave front guided refractive data to quickly and precisely generate the best refractive endpoints and visual satisfaction. Compared to traditional refraction, Wavefront Optimized Refraction what Marco calls the ‘XFRACTION’ process represents a new age in digital refractions.
