Comparison Visual Acuity among different smart phones using PEEK Acuity Application.

Abstract

Objective: To compare visual acuity with Snellen standard chart and peak acuity application using different smart phones.

Methodology: On 398 eyes belonging to 199 patients older than 20 years old, an analytical form of observational study was conducted. Patients with significant ocular disease and a VA of less than 6/60 were not included in the study. For the purpose of simplifying statistical analysis, VA measured via mobile phones (Vivo, Infinix, Redmi, Google pixel) and snellen chart were converted to a log MAR scale. The VA measured using various smartphones and the snellen chart were compared using a one-way ANOVA with Bonferroni.

Results: In the 398 eyes analyzed, there was no significant difference (statistically) between VA determined using the smartphone-based application Peek Acuity and the standard Snellen chart.

Conclusion(s): Visual acuity measured through the application Peek Acuity in different smartphones of varying resolution was comparable to snellen, which concludes that it is advisable that it can be utilized as an efficient, trustworthy, and practical substitute to evaluate VA in tele-ophthalmology despite what phone the professional is using.
