Major field study on self refraction with FocusSpecs in Ghana

Alex Azuka Ilechie, Samuel Abokyi, Andrew Owusu-Ansah, Samuel Bert Boadi-Kusi, Andrew Kofi Denkyira, and Carl Halladay Abraham conducted a study among a total of 203 eligible schoolchildren who completed an examination consisting of SR with FocusSpecs adjustable spectacles, visual acuity with the logMAR (logarithm of the minimum angle of resolution) chart, cycloplegic retinoscopy, and CSR. 

The conclusion of the study was that self-refraction offers acceptable visual and refractive results for young people in a rural setting in Ghana, although myopic inaccuracy in the more negative direction occurred in some children.
