Rapid assessment of avoidable blindness (RAAB) is a rapid survey methodology developed at ICEH. It is a population-based survey of visual impairment and eye care services among people aged 50 years and over.
The main aims of RAAB are:
- To estimate the prevalence and causes of avoidable blindness and visual impairment in people aged 50 and above
- To assess cataract surgical coverage
- To identify the main barriers to the uptake of cataract surgery
- To measure the outcome after cataract surgery.
