Outcome Measures
Primary Outcomes (2)
to obtain a predetermined number of valid ocular biometry measurements per participating site
The test that will be performed are the eye dominance, uncorrected and corrected distance visual acuity (UDVA and CDVA), (accommodation, ocular refraction (automatic refraction), spectacle refraction, axial length (optical, ultrasound), anterior segment biometry (anterior chamber depth), corneal topography (keratometry), contrast sensitivity (Pelli-Robson/ Sine Wave Contrast Test (SWCT), pupil size (gauge)), intraocular pressure, the VFQ-25 questionnaire and some demographic data (age, gender, ethnicity, eye color, highest education).
