AIM:To investigate the prevalence situation of age-related cataract, cataract operation load and the situation of patients voluntarily accept the operation in Zhongshan City, and to establish appropriate intervention policy in order to better carry out the work of prevention and cure blindness.METHODS:Cataract epidemiology investigation were performed in ≥50 year-old permanent population by cluster sampling method in east, west, south, north, center 5 townships of Zhongshan City. All subjects were examined history, visual inspection, slit-lamp microscope to check whether the crystal is muddy. Based on cataract diagnostic criteria, local prevalence of cataract was known.RESULTS:In 66 034 subjects, cataract overall prevalence rate of ≥50 year-old subjects was 46.71%. The female prevalence was higher than male, and with the growth of age, prevalence of cataract increased significantly. Cataract surgery load capacity was 15.83%, the surgery acceptance rate of patients was 43.00%.CONCLUSION:Cataract surgery load is high, while the situation of patients voluntarily accepting the operation is low. Cataract blindness prevention is a long-term work, making appropriate intervention strategies and improving the surgery acceptance rate of patients.
