Abstract

PURPOSE: To compare the aberrometry-derived refractive error measurements from the IRX3 aberrometer (Imagine Eyes, Orsay, France) with a standardized measure of refractive error from the Shin-Nippon SRW-5000 (Japan) autorefractor in a large sample of school-aged children.METHODS: Participants were a subgroup of children from the Northern Ireland Childhood Errors of Refraction Study phase 2 (n = 161 9 to 10 years; n = 147 15 to 16 years). Refractive error was measured under cycloplegia (1.0% cyclopentolate HCl) with the IRX3 aberrometer followed by measurement with the Shin-Nippon autorefractor. Mean differences and 95% confidence intervals and limits of agreement were calculated for refractive vector components (M, J0, and J45).RESULTS: Participants had a wide range of refractive error ranging from -6.00 to +8.00 diopters (D) spherical equivalent refraction. Fixed measurement biases (±95% confidence interval) between instruments were small for both groups (9- to 10-year-olds: M, -0.20 ± 0.65 D; J0, -0.005 D; J45, 0.05 D; 15- to 16-year-olds: M, 0.03 ± 0.61 D; J0, -0.04 D; J45, -0.02 D). Statistically significant differences were found between instruments for M and J45 for the 9- to 10-year-old group (p <0.0001) and for J0 for the 15- to 16-year-old group (p = 0.003). A statistically significant proportional measurement bias was found for the cylindrical components J0 and J45 for both groups (p <0.0001), but no statistically significant proportional bias was found for M for either group.CONCLUSIONS: This is the first study to explore refractive error measurements from the IRX3 aberrometer in children. The differences between instruments for all refractive components (M, J0, and J45) were small for both groups (
