AIM
To describe Cataract Surgical Coverage (CSC) as an indicator to measure the impact of cataract intervention programmes.
METHODS AND MATERIALS
Cataract Surgical Coverage, both for 'eyes' as well as 'persons', was calculated from community based surveys conducted in 19 rural districts in the south-west and one urban district in the north-west of India.
RESULTS
Cataract Surgical Coverage (VA<3/60) ranged from 42% to 68% (for persons) and from 22% to 45% (for eyes) in 19 districts of Karnataka State. The coverage for males was higher than for females. In Ahmedabad the coverage was high with 93% for persons and 83%for eyes.
DISCUSSION
Together with prevalence data, Cataract Surgical Coverage can provide important information on the impact of cataract intervention programmes. Regular assessment of prevalence and coverage indicators through focused community surveys will reveal trends. Coverage indicators are also important as input data for mathematical models to predict future trends in cataract blindness.
目的
将白内障手术覆盖率（CSC）描述为衡量白内障干预项目影响的一项指标。
方法与材料
“眼”和“人”的白内障手术覆盖率是根据在印度西南部19个农村地区和西北部1个城市地区开展的社区调查计算得出的。
结果
卡纳塔克邦19个地区的白内障手术覆盖率（视力<3/60），按“人”计算为42%至68%，按“眼”计算为22%至45%。男性的覆盖率高于女性。在艾哈迈达巴德，覆盖率较高，按“人”计算为93%，按“眼”计算为83%。
讨论
结合患病率数据，白内障手术覆盖率可为白内障干预项目的影响提供重要信息。通过有针对性的社区调查定期评估患病率和覆盖率指标将揭示其趋势。覆盖率指标作为数学模型预测未来白内障致盲趋势的输入数据也很重要。
