Comparison of a Novel Binocular Refraction System with Standard Digital Phoropter Refraction.

There was also no systematic bias, although a slight trend to more minus spherical power (0.03 D) was found with the novel technique compared with the standard refraction, which is much lower than within examiner variation. 5 , 13 , 23 Clinicians can expect equivalent refraction end points whether using the standard phoropter refraction technique or the novel Chronos binocular refracting system in adult patients.
