Follow-up survey of cataract surgical coverage and barriers to cataract surgery at Nkhoma, Malawi.

Purpose: Nkhoma Eye Hospital, Malawi provides high volume, high quality free cataract surgery to people in its catchment region of Central-Malawi. However, a previous survey in 2000 indicated that only 1 in 7 people with bilateral blindness from cataract had received surgery in a 10-mile radius of Nkhoma.Methods: We conducted a population-based survey in 2006 in the 32 villages within a 10-mile radius of Nkhoma Hospital in people aged ≥ 40 years in order to investigate the cataract surgical coverage (CSC) and barriers to cataract surgery.Results: The prevalence of blindness (visual acuity [VA] <3/60 in better eye) in 835 people aged ≥ 40 was 1.3% (95% CI 0.5–2.1), of which 36.4% was due to cataract. Overall, the CSC was 83.3%, and for eyes (VA<3/60) was 66.0%. The CSC was lower in females compared to males (73.3% vs. 100.0%. P < 0.001). The most common barrier to surgery was cost (58%).Conclusion: Our results demonstrate a 5-fold increase in coverage in the 6 years, primarily by increasing efficiency of t...
