Cataract may cause moderate vision impairment (<6/18 to 6/60), severe vision impairment, (<6/30 to 3/60) or blindness (<3/60). People may have bilateral or unilateral cataract, so it is more useful to consider the number of eyes than the number of people who require surgery. Cataract surgical rate (CSR) is the number of cataract operations performed in one year, per million population. It is a ...

In many countries, the number of cataract operations performed is inadequate to deal even with the people who have newly become blind from cataract, let alone those who are already blind or visually impaired. There is, therefore, a backlog of cases needing surgery. This could be due to low surgical capacity (people are on a waiting list) or to a lack of demand for cataract surgery (people haven...

To begin to meet the need for cataract surgery in sub-Saharan Africa, the cataract surgical rate (CSR) should be at least 2,000 to 3,000; i.e. there should be 2,000-3,000 cataract operations per million population, per year. The current levels are below 1,000 (and often much lower). Sub-Saharan Africa poses a unique set of challenges: low population density; inadequate transportation systems th...

OBJECTIVE Cataract though avoidable remains as leading cause of blindness in Nepal. Though, Himalaya Eye Hospital rendering high quality surgical service through its base hospital and out reach service in Gandaki Zone having cataract surgical rate is below 1500 per million. Therefore, it is mater of interest to investigate the reason and the finding would be helpful to plan the future cataract ...
