PURPOSE: To study the optimal method for delivery of spectacles at eye camps to maximize procurement and use.
METHODS: A cluster randomized controlled trial, undertaken in the catchment districts of Aravind Eye Hospital - Theni, in the state of Tamil Nadu, India. Community eye camps (n = 21) were allocated to offer one of three types of service for purchase of spectacles to correct refractive error: (1) Issuance of a prescription only; (2) booking orders for spectacles with subsequent delivery; (3) on-the-spot fitting and dispensing of spectacles. Follow-up questionnaires were administered 6 weeks after interventions to assess patient outcomes. The primary outcome measured was spectacle procurement at follow-up 6 weeks post-screening. Secondary outcomes included use of and satisfaction with spectacles. Reasons for purchase/non-purchase were also assessed.
RESULTS: Compared to those who were issued only a prescription and adjusting for distance from base hospital, spectacle procurement was significantly higher for those allowed to book spectacles for subsequent delivery (odds ratio, OR, 8.79, 95% confidence interval, CI, 4.61-16.78) and for those receiving spectacles on the spot (OR 13.97, 95% CI 8.12-24.05). Among those with spectacles at 6 weeks, spectacle use was nearly universal and satisfaction with spectacles varied between 92 and 94% among the three different dispensing modalities.
CONCLUSION: Making spectacles available on the spot is important to ensure procurement in a context where availability and access to dispensing opticians is poor.
