Durr NJ, Dave SR, Lim D, et al. Quality of eyeglass prescriptions from a low-cost wavefront autorefractor evaluated in rural India: results of a 708-participant field study. BMJ Open Ophthalmology 2019;4:e000225. doi:10.1136/ bmjophth-2018-000225

Key findings
  • Eyeglass prescriptions can be accurately measured by a minimally trained technician using a low-cost wavefront autorefractor in rural India.
  • Data from 708 participants indicate a marginal difference in both prescription preference and resulting visual acuity between eyeglasses derived from subjective refraction versus QuickSee autorefraction (VA from QuickSee was on average only one eye chart letter worse).
  • Among the 438 participants 40 years old and younger, there was no statistically significant difference in the preferences for eyeglasses derived from subjective refraction versus QuickSee autorefraction.

Key findings
  • It is possible to build an autorefractor that is portable, affordable, and robust using low-cost components and no moving parts.
  • A prototype version of the QS technology is as accurate as a high-end commercial autorefractor in predicting refraction of an adult population
