  • Accuracy of a Smartphone-based Autorefractor Compared with Criterion-standard Refraction. [Journal Article]
  • OVOptom Vis Sci 2018; 95(12):1135-1141
  • Jeganathan VSE, Valikodath N, … Woodward MA
  • CONCLUSIONS: Uncorrected refractive error is a prevalent problem throughout the world especially among the low-income population who have limited access to professional eye care and cannot afford eyeglasses.The portable autorefractor had small but clinically significant differences from subjective refraction. The device's scores on the usability scale indicate good overall patient acceptance. The device may be valuable for use where there is limited access to a trained refractionist.
  • Human resources for refraction services in Central Nepal. [Journal Article]
  • CEClin Exp Optom 2015; 98(4):335-41
  • Kandel H, Murthy GV, Bascaran C
  • CONCLUSIONS: The study findings demand a major effort to develop appropriately trained personnel when planning refraction services in the Central Region and in Nepal as a whole. The equitable distribution of the refractionists, their community-outreach services and awareness raising activities should be emphasised.
  • Accuracy of rural refractionists in western China. [Multicenter Study]
  • IOInvest Ophthalmol Vis Sci 2014 Jan 07; 55(1):154-61
  • Zhou Z, Zeng J, … Congdon N
  • CONCLUSIONS: Rural refractionists in western China have little formal training and frequently fail to optimize VA among children, even when autorefractors are used. Training is needed emphasizing better use of automated refraction, particularly in children with astigmatism and hyperopia.
  • A guide to performing basic manifest refractometry. [Review]
  • JOJ Ophthalmic Nurs Technol 2000 Mar-Apr; 19(2):84-93; quiz 94-5
  • Garber N
  • Refractometry provides the ophthalmologist with the prescription that has the most plus power with the best vision. This eliminates the need for the patient accommodating to achieve clear vision at d…
  • A fully automated remote refraction system. [Journal Article]
  • JTJ Telemed Telecare 2000; 6 Suppl 2:S16-8
  • Dyer AM, Kirk AH
  • Traditional methods of performing refractions depend on a trained refractionist being present with the subject and conducting an interactive form of subjective testing. A fully automated refraction s…
