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.

Outcome Measures
Primary Outcomes (1)
Spherical equivalent
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.
Day 1
Interventions
As of today, no published clinical studies have been conducted with the Vision-S™ 700 neither Vision R 800
Eligibility Criteria
6 to 16 years old patients followed in the Brest University Hospital Center, in France, between the 1st of November 2022 and the 30th of April 2023 and requiring a cycloplegic refraction not presenting an exclusion criteria
You may not qualify if:
- age below 6 years or above 16 years
- presence of other ophthalmological pathologies rather than ametropia
- non-French language proficiency, and absence of parental authorization
