    Screening for hyperopia in infants using the Power Refractor

    Stiani NG., Mutti DO. Optom Vis Sci 2011;88(8):905-911

    Accessory +4.50 diopter sphere spectacles appeared to successfully extend the operating range of the PR with cycloplegia, allowing for detection of high levels of hyperopia that occurred in a large proportion of 2-month old infants with adequate sensitivity and specificity compared with cycloplegic retinoscopy.
