Refraction Determination Analysis

September 3, 2015 updated by: Coad Dow, MD, Lee, Steven, M.D.
Correlating the accuracy of a refraction done over telemedicine to that of a standard refraction, with a study hypothesis that the results will be equivalent.

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Telemedicine refraction before traditional refraction
We will first refract an individual using telemedicine refraction, and then refract them using a traditional refraction method.
Device: Telemedicine refraction
Other Names:
  • Glasses,
  • Contact lenses,
  • Refractive surgery,
Device: Traditional refraction
Experimental: Traditional refraction before telemedicine refraction
We will first refract an individual using a traditional refraction, and then refract them using a telemedicine refraction method.
Device: Telemedicine refraction
Other Names:
  • Glasses,
  • Contact lenses,
  • Refractive surgery,
Device: Traditional refraction
