•1. Eye drops (tear fluid substitutes) used prior to the measurement (at least 2 hours without eye drops; except mydriatic agents for pupil dilatation).
•2. Any performed contact measurements or examinations in which the eye is touched on the same day prior to the investigation measurement.
•3. Physical inability to be positioned at the study devices (e.g. torticollis, head tremor, etc.).
•4. Permanent insufficient eyelid opening or eyelashes, which partially conceal alignment or keratometry reflections, inhibiting valid measurements (i.e. typical keratometry measurements with 3-4 mm zone should be ensured).
•5. Rigid contact lenses wearing within one day prior to the measurement (if worn, lenses should be removed at least one day prior to the measurements).
•6. Soft contact lenses wearing within one day prior to the measurement (if worn, lenses should be removed at least one day prior to the measurements).
•7. Principal Investigator’s determination that the subject is not suitable due to other medical condition (reasons to be listed on eCRF).
•8. Known Pregnancy.
•9. Patients who are participating in another ophthalmological clinical study.
