NCT07336069

Brief Summary

This clinical trial aims to assess the efficacy and safety of the Shilangqing Smart Reading Aid, a head-mounted device integrating XR and AI technologies, in improving reading performance and quality of life among children with low vision. The study employs a multicenter, randomized, controlled design with two parallel groups: an experimental group using the Shilangqing device and a control group using traditional optical magnifiers. Participants will undergo a 12-week intervention period, with primary outcomes focusing on reading speed, accuracy, and user satisfaction. Secondary outcomes include changes in visual acuity, eye health metrics (e.g., tear film stability, visual fatigue), and device-related adverse events. The trial builds on preliminary data from Zhongshan Ophthalmic Center and user feedback indicating high efficacy and safety. An estimated 120 participants aged 6-18 years with best-corrected visual acuity of 0.05 to \<0.3 will be recruited from multiple sites in China. Results will inform clinical adoption and regulatory approvals for low-vision assistive devices.

Outcome Measures

Primary Outcomes (1)

  • Asthenopia score

    Participants completed the Visual Fatigue Subjective Scale questionnaire post 30-minute reading session (MEMC and non-MEMC). This 20-item scale assessed eye strain, headaches, perceived clarity, and general comfort, with responses analyzed to identify differences in subjective visual fatigue between conditions.
