Epidemiology and trends in the uptake of refractive error services in Harare, Zimbabwe: a hospital-based retrospective study.

Abstract

The study aimed to determine the epidemiology and evaluate the trends in the uptake of refractive error services in Harare. A clinic-based retrospective study at the Greenwood Park Eye Centre and its three subsidiaries was conducted from January 1, 2015 to December 31, 2020. 12,216 patients' records were retrieved, out of which 1074 (8.79%) had refractive error cases. The prevalence of visual impairment at presentation was 5.80% [95% CI: 5.39 - 6.23]. Among those with refractive error, the sample prevalence of visual impairment before correction was 41.30% [CI: 38.3 - 44.3, 95%], and 2.20% [95% CI: 1.4 - 3.3] after correction. There was inconsistency in the percentage utilization of refractive error services, with the highest being 42.60% in 2015. Refractive error types were related to age, employment position, and type of visual impairment prior to refractive error treatment. There was a low percentage of refractive error services uptake in urban Zimbabwe.
