Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Agreement in refractive prescriptions between operators from different professional backgrounds and senior optometrists using the same automated refraction program | Day 1, after completion of both subjective refraction examinations | |
| Secondary | Examination time for comparison operators and senior optometrists using the automated refraction program | Day 1, during each subjective refraction examination. | |
| Secondary | Participant acceptance, comfort, and satisfaction with the automated refraction procedure | Day 1, after completion of both subjective refraction examinations. | The questionnaire assesses three aspects: understanding and operation, comfort and visual fatigue, and acceptance and willingness to use. Each item is rated on a 5-point Likert scale from 1 ("strongly disagree") to 5 ("strongly agree"), with higher scores indicating a more favorable evaluation. |
| Secondary | Adverse events and ocular discomfort during the examinations | Day 1, during both subjective refraction examinations. |
