TL;DR
The prevalence of blindness in > or =50-year-olds in Nakuru district was low, in part due to the high cataract surgical coverage, and the RAAB is easy to use and inexpensive and provides information about the magnitude and causes of avoidable blindness that can be used for planning and monitoring eye care services.
Abstract
The prevalence of blindness in > or =50-year-olds in Nakuru district was low, in part due to the high cataract surgical coverage.

In situations where quality of fieldwork can be guaranteed, the EPI random walk method can give accurate and precise results, however, compact segment sampling is generally to be preferred as it ensures objectivity in household selection and permits the estimation of population totals, which are helpful for planning service provision.
British Journal of OphthalmologyDoes prospective monitoring improve cataract surgery outcomes in Africa?
110 Citations2002David Yorston
This study demonstrates improvement in visual outcome results after cataract surgery over a 1 year period, associated with a change in surgeons' attitudes, leading to greater emphasis on appropriate case selection, better management of surgical complications, and improved visual outcomes.

Ass assessments indicate that outcome with available correction was poor in 15-25% of eyes following cataract surgery, and visual outcome is likely to improve when better correction for aphakia can be provided.

Rapid assessments for cataract blindness in those aged > or = 50 years can be conducted at district level in India with existing resources and at affordable costs and provide reliable data, essential for effective monitoring and planning.

81 Citations2003Rainald Duerksen, Hans Limburg +2 more
There is a need to increase the cataract surgical coverage in Paraguay because the number of eye surgeons is adequate but the accessibility of cataracts surgical services in rural areas and the affordability of surgery to large sections of society are major constraints.

54 Citations2002Sh A Amansakhatov, Z P Volokhovskaya +2 more
To increase the cataract surgical coverage in Turkmenistan the intake criteria should be lowered to VA <6/60 or less, and the visual outcome of surgery can be improved by expanding the number of IOL surgeries and routine monitoring ofCataract outcome.

46 Citations2004Hans Limburg
Routine monitoring of cataract outcome should be used by individual surgeons or centres to follow trends in their own results over time, and not to compare surgeons, in an atmosphere of trust and support.

Most of the cases of blindness and of serious deficiency in visual acuity in persons 50 years old or older in Piura and Tumbes are due to uncorrected refractive defects, especially cataract, which could be reduced with measures that facilitate access to appropriate treatment.

The number ofCataract operations in Chakwal District can be increased by reducing the threshold for cataract surgery to VA < 6/60 or less, and a special approach to operate more females may be required.

As in other settings, cataract surgical coverage was lower in women than in men, and surgical promotion programs will need to focus on differentiating intraocular lens surgery from (previously practised) intracapsularCataract extraction surgery.
