Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference between spherical, cylindrical measurements & axis alignment obtained by the 3nethra Specto and those obtained by subjective refraction using trial frame and Difference between spherical, cylindrical measurements & axis alignment obtained by the 3nethra Specto and those obtained by the Topcon Phoropter.Timepoint: In one visit at a time span of 1 hour | — |
Secondary
| Measure | Time frame |
|---|---|
| Repeatability (Precision) of Measurements: The consistency of spherical, cylindrical, and axis measurements obtained by the 3nethra Specto over two repeated tests. Time Efficiency: The time taken to complete the refraction process with the 3nethra Specto compared to the time taken using subjective refraction with a trial frame. Patient Comfort: Patient-reported comfort levels during the refraction process with the 3Nethra Specto, assessed using a standardized comfort questionnaire.Timepoint: In one visit at a time span of 1 hour | — |
