Key findings
Visual acuity resulting from correction based on QuickSee measurements was the same as that achieved by subjective refraction in 87% of the eyes. This improvement in visual acuity is comparable to that reported for clinically established benchtop systems.
Agreement between the three refraction components (M, J0, J45) provided by QuickSee and subjective refraction is within 0.5 D in more than 85 % of the cases.
This research suggests that QuickSee provides measurements that agree more closely with subjective refraction than other handheld autorefractors.
