Assessment centreEye measuresRefractometry ⏵ Refractometer 1


This 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 and continued through the repeat visit in 2012.
