ABSTRACT
The objective of this study was to establish the prevalence of cataract and measure vision related quality of life among elders in Sri Lanka. The 4-part study consisted of a survey to establish cataract prevalence, a case control study of risk factors, an assessment of the National Eye Institute Visual Functional Questionnaire (NEI-VFQ), and a comparison of quality of life among elders with and without cataract. Cataract prevalence was 56%. Significant risk factors were age, being female, occupational exposure, lower social class, presence of chronic illnesses, and smoking. The NEI-VFQ was validated for use in Sri Lanka and quality of life of elders with cataract was significantly lower on the NEI-VFQ and 2 other standard measures. The findings inform the development of public health strategies for treatment and prevention of cataract in Sri Lanka where the impact of cataract is increasingly being felt with rapid population aging and are applicable to other developing countries.
