Tidsramme |
|---|---|---|
|
Effective Refractive Error Coverage
Tidsramme: At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Effective refractive error coverage among the surveyed population, calculated at the person level as the proportion of participants with met refractive correction need among all participants with met, under-met, or unmet refractive correction need.
The primary threshold will be worse than 6/12 in the better eye, corresponding to decimal visual acuity less than 0.5, with improvement to 6/12 or better through habitual correction, pinhole, or refraction used to classify met, under-met, and unmet need.
|
At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
|
Effective Cataract Surgical Coverage
Tidsramme: At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Effective cataract surgical coverage among the surveyed population, calculated at the person level as the proportion of participants with operated cataract and a good visual outcome among all participants with operated or operable cataract.
Good visual outcome is defined as presenting visual acuity of 6/12 or better; the final operable cataract threshold should be confirmed before release.
|
At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
|
Effective Hearing Technology Coverage
Tidsramme: At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Effective hearing technology coverage among the surveyed population, calculated as the proportion of participants with moderate or greater hearing loss who regularly use hearing technology and report perceived benefit from its use.
Hearing loss classification will be based on WHOears app screening and study questionnaire data.
|
At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.

Prevalence and Correction Status of Common Eye Diseases
Tidsramme: At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Prevalence and correction or treatment status of common eye diseases, including refractive error and cataract, based on standardized eye examinations and questionnaire data.
|
At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
|
Prevalence of Dual Sensory Impairment
Tidsramme: At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Prevalence of dual sensory impairment, defined as the proportion of participants who meet both the study visual impairment criterion and the study hearing impairment criterion.
The visual impairment criterion will use worse than 6/12 in the better eye, corresponding to decimal visual acuity less than 0.5; the hearing impairment criterion will be based on WHOears app screening and study questionnaire data.
|
At the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.

Feasibility and Satisfaction of the SENSIIS System for Primary-Level Vision and Hearing Screening
Tidsramme: At or after the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
|
Feasibility and satisfaction of the SENSIIS system for primary-level vision and hearing screening, assessed through questionnaires and interviews.
|
At or after the cross-sectional survey visit during the 2026-06 to 2026-12 data collection period.
