Background: In India, overall prevalence of blindness is 1.1%, the principal cause being cataract (62.6%) affecting over 9 million people. Aim: The present study was carried out to find the prevalence, barriers and facilitating factors related to cataract health services in a rural community of Tamil Nadu. Methods: The study was carried out in four villages in sub-center Kondur, under Primary Health Centre (PHC) Kondur, Villupuram district, Tamil Nadu, during November-December 2010. All adults of more than 50 years (n = 331) residing in the sub-center Kondur, were examined for lenticular opacity and visual acuity. A structured proforma was used to assess the awareness, barriers and facilitating factors related to available cataract health services. Results: The prevalence of cataract among the population studied was 62.8% (95% confidence interval [CI]: 57.5-67.9%). There was a significant increase in cataract with increase in age (P < 0.001). Only 13% (95% CI: 9.6-16.3%) of the persons with cataract were operated at the time of interview. The major barriers were no one to accompany (25.5%) and absence of felt need (22.6%). Less than one-fifth (17.8%) reported the awareness of cataract as a condition affecting eye. The facilitating factors were free surgery in camps (83.7%), self-decision due to defective vision (69.7%) and quality of service provided (65.1%). More than one-half (56.7%) of subjects diagnosed for cataract during the survey were willing to be operated. Conclusion: Prevalence of cataract was high in Kondur PHC area. It is vital to increase the level of awareness regarding the need and availability of cataract health services.
