Rapid assessment of cataract surgical coverage in rural Zululand
1International Centre for Eye Health (Department of Preventive Ophthalmology), Institute of Ophthalmology, London.
Objective:
Cataract surgical coverage (CSC) is a useful indicator of the degree of success of a cataract intervention programme. However, because previously described methods are time-consuming and labour-intensive, they are rarely performed. This study describes a simple and inexpensive assessment of CSC based on screening of pensioners at pension delivery sites in a rural district.
Design:
Random cluster-based cross-sectional survey.
Setting:
State pension distribution sites in Hlabisa, a rural district in KwaZulu-Natal, South Africa.
Subjects:
562 old-age pensioners.
Method:
Subjects found to be blind (visual acuity < 3/60) and those reporting a history of eye surgery were examined using a torch and direct ophthalmoscope by an ophthalmologist.
Outcome Measures:
Cases of blindness due to operable cataract and post-cataract surgical subjects were identified.
Results:
CSC was found to be 38.5% (95% confidence interval 29.1-47.9%). Blindness prevalence was 10.3%, with 69.0% due to cataract.
