Current refraction assessment in children is dependent on the Eye Care Specialist and lacks standardization. Essilor has developed new algorithm assisted subjective refraction software dedicated to children of 6-12 years old and suitable for use with Vision-S™ and Vision-R™ phoropters, in addition to existing software.
Two different versions of the software have been developed: the first incorporating only the steps needed to perform an entire subjective refraction process (vA), and the second, identical to the first but incorporating additional steps useful for managing the child's attention and cooperation (vB).
The software performance in terms of subjective refraction results will be compared to a conventional subjective refraction method performed with the Vision-R™700 phoropter in manual mode.
