Paul M. Karpecki, OD, FAAO, explains how the Point Spread Function (PSF) Refractor by Vmax Vision, differs from a typical phoropter. He highlights that patients value his ability to off them the latest technology. A key differential is the perception that he has the latest technology in his practice and it’s ability to show patients their old prescription compared to any new correction with just a touch of a button. Mark Schaeffer, OD, further describes how the PSF Refractor helps clinicians achieve visual acuities better than 20/20 for their patients and allows for a sharper, more accurate prescription.
