Brief summary
This study aimed to compare refractive measurements using Vision-S™ 700, an immersive and compact phoropter with a tunable-focus lens, and Vision-R™ 800, a phoropter with a tunable-focus lens without immersion, with cycloplegic refraction serving as the gold-standard. This a retrospective study aimed to enroll 41 children, aged 6 to 16 years, who underwent refractive assessments with Vision-S™ 700, Vision-R™ 800, and cycloplegic refraction. The primary objective involves a comparison of the spherical equivalent between both devices and compared to cycloplegic refraction. Secondary outcomes include the analysis of astigmatism components (J0° and J45°) and subgroup analyses in myopic and hyperopic children.

| Spherical equivalent | Day 1 | The primary outcome of this study was to compare the spherical equivalent, obtained using two different devices: Vision-S™ 700, an immersive phoropter with a tunable-focus lens, and Vision-R™ 800, a phoropter with a tunable-focus lens without immersion. The study aimed to assess the overall agreement of these measurements with cycloplegic refraction, considered the gold standard in this context. |
