The awe expressed by patients after experiencing the Marco TRS Digital Refractor provides a value that cannot be quantified. Further, the precision of the final refraction allows for truly excellent vision, a great reduction in remakes and, most importantly, happy patients. From the data upload to final refraction is 3-5 minutes, allowing for more than two patients more per day, which, in turn, generates an increase in revenue of $696. Our optical sales have increased each year at least 15 percent on average.
