Autorefraction ⏴ Eye measures ⏴ Physical measures ⏴ Assessment Centre
DescriptionThis category contains data on measurements related to the assessment of the participant's eye prescription (refractive error), using a TomeyRC - 5000 device. This category includes data on whether the measurement was made, and the test result for refractometry (Sphere, Cylinder, Axis, Pupil diameter) and keratometry (corneal refraction and astigmatism) for each eye. This measure was added to the assessment visit towards the end of recruitment.
Please note that these data fields have not yet been summarised into a form suitable for non-specialists and require expert knowledge for analysis. Derived summary variables will be incorporated into the resource when this work is complete.
