What researchers measure

Primary outcomes

  1. Best Spectacle-Corrected Distance Visual Acuity (BSCDVA)

    BSCDVA will be assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts. The score ranges from 0 to 100, with a higher score representing better visual functioning.

    Time frame: Baseline to 12 months

Secondary outcomes

  1. Vision-related Quality of Life as Assessed by the National Eye Institute 25-Item Visual Function Questionnaire (NEI-VFQ-25)

    The score on the NEI-VFQ-25 ranges from 0 to 100, with a higher score indicating greater functioning.

    Time frame: Baseline to 12 months
