Study Purpose: To evaluate the level of agreement between the Acuvera Capture application and traditional paper-based methods for recording Best Corrected Visual Acuity (BCVA) in ophthalmic clinical trials. The study aims to determine whether the electronic capture system provides equivalent or improved accuracy, consistency, and error reduction compared with paper-based recording, thereby supporting its potential adoption as a reliable method for BCVA data collection in clinical research.
30 participants (33%) in the normal/near-normal BCVA range (≤0.3 logMAR ≥70 letters); ≈20/40 or better);
30 participants (33%) with mid-range BCVA (0.4-0.9 logMAR (36-69 letters); 20/50 to 20/200)
30 participants (33%) with low vision BCVA (≥ 1.0 logMAR (≤35 letters); worse than 20/200) including off-chart acuities using protocol low-vision procedures).
Adults ≥18 years old
Any condition preventing reliable completion of BCVA testing (e.g., severe cognitive impairment, language barriers)
Inability or unwillingness to comply with study requirements
Non-ophthalmic condition that precludes safe or reliable testing (e.g., immediate post-operative systemic status preventing cooperation).
Any circumstance that, in the investigator's opinion, makes the eye/participant unsuitable for accurate BCVA testing or for completing both data-capture methods during the same visit.
