Design outcomes

Primary

Measure	Time frame
- Refractive outcomes Values of the sphere, cylinder and axis components, obtained by the following tests: 1: automatic, 2: manifest and 3: online (Easee). These are converted into vectors by Fourier analysis.	—

Secondary

Measure	Time frame
- Visual acuity (converted into LogMAR values for statistical analysis) - Gender (men/women) - Telemetry (duration of the test in minutes) - Age (in years) - Degree of ametropia (in diopters)	—
