I have to say there is only one word to describe the Marco RT-5100. WOW. That word not only describes how much easier, faster, and more efficient it is to do refractions, but also is the word my patients use when I am done. They are positively amazed at the technology and convinced that my office is cutting edge and engaged in the latest and best equipment in fulfilling their eye care needs. The investment made in the purchase of the RT-5100 is an investment in patient management and patient retention. My only regret is not buying it sooner. I absolutely look forward to filling all my lanes with this system. Way to go Marco, thanks for making my life simpler.
