To determine the cataract surgical coverage (CSC) in the close proximity of Nkhoma Hospital, Malawi.
A rapid epidemiological assessment of the population aged 40 years and over was undertaken to determine the proportion of eyes and patients with cataract blindness that had previously received cataract surgery within a 10-mile radius of the hospital.
A total of 993 people aged 40 years and above from all 31 small villages in the 10-mile radius were examined. The prevalence of blindness in this age group was 3.72%, of which 62% was due to cataract. The cataract surgical coverage for people with blinding cataract was calculated at 14.8%, and for eyes with cataract (visual acuity <3/60) 8.5%.
Nkhoma Hospital has provided affordable cataract surgery for more than 20 years. Despite this, within a ten-mile radius of the hospital, only 1 in 7 people with bilateral blindness from cataract has received surgery.
确定马拉维恩科马医院附近地区的白内障手术覆盖率（CSC）。
对40岁及以上人群进行快速流行病学评估，以确定在医院10英里半径范围内曾接受白内障手术的失明眼及患者的比例。
对半径10英里内所有31个小村庄的993名40岁及以上人群进行了检查。该年龄组失明患病率为3.72%，其中62%由白内障所致。致盲性白内障患者的白内障手术覆盖率为14.8%，白内障眼（视力<3/60）的手术覆盖率为8.5%。
恩科马医院提供价格亲民的白内障手术已逾20年。尽管如此，在医院10英里半径范围内，每7名双侧白内障致盲患者中仅有1人接受了手术。
