PURPOSE. To assess presbyopic spectacle coverage, willingness to pay, and the impact of correcting uncorrected presbyopia in individuals 40 years of age and older in Zanzibar and whether assessment of presbyopia can be incorporated into Rapid Assessment of Blindness (RAAB) surveys. METHODS. A cross-sectional, population-based survey of presbyopia was incorporated into a RAAB survey. The sample size of 400 included individuals older than 50 years (from RAAB survey) and those 40 to 50 years old (from the same household) who had a corrected visual acuity (VA) of at least 6/18 in either eye. An Ophthalmic Clinical Officer (OCO) administered visual function (VF) and ...
