Gil A, Hernández CS, Pérez-Merino P, Rubio M, Velarde G, Abellanas-Lodares M, et al. (2020) Assesment of the QuickSee wavefront autorefractor for characterizing refractive errors in school-age children. PLoS ONE 15(10): e0240933.
Key findings
The high-level of agreement between QuickSee and subjective refraction, as well as the resulting VA achieved by the patients in both study groups, suggest that the device would serve as a useful autorefraction tool for pediatric populations.
The device’s robust screening metrics, along with its ease of use and handheld form factor, support its use as a pediatric vision screening tool.

Key findings
Visual acuity resulting from correction based on QuickSee measurements was the same as that achieved by subjective refraction in 87% of the eyes. This improvement in visual acuity is comparable to that reported for clinically established benchtop systems.
Agreement between the three refraction components (M, J0, J45) provided by QuickSee and subjective refraction is within 0.5 D in more than 85 % of the cases.
This research suggests that QuickSee provides measurements that agree more closely with subjective refraction than other handheld autorefractors.

Key findings
Es posible construir un autorrefractor que sea portátil, económico y robusto utilizando componentes de bajo costo y sin partes móviles.

Key findings
Un técnico mínimamente capacitado puede medir la prescripción de gafas con precisión utilizando un autorrefractor de frente de onda de bajo costo en la India rural.
Los datos de 708 participantes indican una diferencia marginal tanto en la preferencia de prescripción como en la agudeza visual resultante entre las gafas derivadas de la refracción subjetiva frente a la autorefracción del QuickSee (la AV del QuickSee fue en promedio solo una letra de la tabla optométrica peor).
Entre los 438 participantes de 40 años o menos, no hubo diferencias estadísticamente significativas en las preferencias por las gafas derivadas de la refracción subjetiva frente a la autorrefracción del QuickSee.
