I recently purchased the WAM700 (Wave Analyzer Medica 700 Wavefront Abberrometer) after reviewing other similar instruments on the market. This instrument is great! By doing 7 different measurements within 2 minutes per eye, it is a time saver and money generator! My staff loves the ease of this machine, I like the data it provides without having to use multiple different devices and the patients are impressed with the technology. I highly recommend the WAM700.
