The problem of senile cataract blindness (SCB) is very acute in India, contributing to 80 per cent of total blindness. The national objective of reducing the prevalence of blindness from 1.49 per cent, during 1986-89 to 0.3 per cent by AD 2000 has necessitated the surgical correction of SCB to be the major activity. With the introduction of District Blindness Control Society (DBCS), there has been a substantial increase in the number of operations of SCB in those districts. However, in the absence of standard, feasible, simple and cost effective methods to estimate the prevalence and incidence of SCB, the DBCS may find it difficult to plan and execute its major activity in a realistic way. The paper suggests two such methods for the use by DBCS. Only five seemingly rational assumptions have been adopted for the purpose. The authors feel that proper field testing is required to be sure about the reliability and validity of these methods.
在印度，老年性白内障致盲（SCB）问题非常严重，占总失明人数的80%。将失明患病率从1986 - 1989年期间的1.49%降低到公元2000年时的0.3%这一国家目标，使得对老年性白内障进行手术矫正成为主要活动。随着地区失明控制协会（DBCS）的引入，这些地区老年性白内障手术的数量大幅增加。然而，由于缺乏估计老年性白内障患病率和发病率的标准、可行、简单且具有成本效益的方法，地区失明控制协会可能会发现难以切实地规划和开展其主要活动。本文为地区失明控制协会建议了两种这样的方法。为此仅采用了五个看似合理的假设。作者认为需要进行适当的实地测试，以确保这些方法的可靠性和有效性。
