Design outcomes

Primary

Measure	Time frame
Absolute error correction of intra-pupillary distance (IPD) measured with a novel device versus a reference standard (digital pupillometer operated by an experienced optometrist)Timepoint: Baseline dispensing visit (Day 0): single measurement session. Analysis metrics: mean absolute error and proportion within the success threshold, with between-group comparison (novel device versus existing AI-based device)	—
