Correlation between autorefractor and PlusOptix A09. Top left graph: Correlation between non-cycloplegic autorefraction with PlusOptix A09 and cycloplegic autorefraction with a autorefractor (r = 0.81, p < 0.001); top right graph: non-cycloplegic autorefraction with PlusOptix A09 and with autorefractor (r = 0.70, p < 0.001), down left graph non-cycloplegic autorefraction and cycloplegic autorefraction (r = 0.77, p < 0.001)
