Correcting Myopia Among Secondary School Children to Increase Academic High School Attendance Rates in Rural Communities (SWISH)
Refractive Errors
About this trial
This is an interventional treatment trial for Refractive Errors focused on measuring Refractive error, Myopia, Academic high school attendance, Education attainment, Spectacle wear compliance, Mental health well-being, Progression of shortsightedness
Eligibility Criteria
Inclusion Criteria:
- Year 1 and 2 classes (likely age 12-15 years) at the recruited schools
- Have uncorrected (without glasses) visual acuity of ≤6/12 in either eye;
- Refractive error meets cut-offs shown to be associated with significantly greater improvement in visual acuity when corrected (myopia ≤-0.75 diopters (D), hyperopia ≥2.00 D, or astigmatism (non-spherical refractive error) ≥1.00 D);
- Visual acuity can be improved to >6/12 in both eyes with glasses.
Exclusion Criteria:
- Presence of visually-significant ocular condition besides refractive error
Sites / Locations

Control
Children at Intervention schools will receive free spectacles of a design they select, based on the child's measured refractive power and dispensed at school by the study optometrist. Additionally, teachers (but not children) in eligible classes will be informed that if 80% spectacle compliance as measured across three separate unannounced inspections was achieved, they will be given an incentive of an conditional cash transfer. The cash transfer will be deposited into the teacher's bank accounts directly.
Children at Control schools will receive a glasses prescription and letter to the parents informing them of the refractive status of their child, with free glasses provided only at the end of the trial. No teacher incentive will be offered. Service offered to the Control group exceeds standard care, in that no school-based programs of vision screening and refraction currently exist in the study area, or in most of rural China.
