Comparison of 2Win and plusoptiX A12R refractometers with Retinomax handheld autorefractor keratometer

ConclusionsIn manifest conditions, the accuracy of the 2Win and plusoptiX A12R refractometers is low in hyperopia and astigmatism, but the devices are well correlated with each other, and both have high specificity and low sensitivity in hyperopia, resulting in the underestimation of hyperopic refractive error. The optional Plusoptix sensitive referral criteria seems to be appropriate for the A12R. The 2Win provided fewer inconclusive results and was preferred for use with younger and developmentally delayed children.
