CHICAGO – Vmax Vision Inc. announced the addition of voice-guided instruction software to the Point Spread Function Refractor, its subjective refraction technology. The software audibly guides patients through each refraction test, according to a company press release distributed here at Optometry’s Meeting.
“The addition of automated voice instruction decreases the learning curve for mastering the PSF Refractor from an average of 2 weeks down to 2 or 3 days,” Shui Lai, PhD, founder and CEO of Vmax Vision and inventor of the PSF Refractor. The decrease in refraction training can bring profits to the practice because of the decrease in chair time and more interaction with patients, according to the release.
The instructions activate by pressing a button and are operated by the doctor or technician. The instructions can be repeated as necessary and are provided in English, with other languages available in future software updates.
The PSF Refractor measures a patient’s subjective visual response to a point source and has five times greater accuracy than the phoropter, according to the company. It corrects for higher-order aberrations and corrects nighttime specific visual aberrations.
