Section snippets
Study Population
The Liwan Eye Study is a population-based cohort study carried out in an urban district of Guangzhou, Southern China. Detailed information of the baseline methodology of the Liwan Eye Study has been described elsewhere.22 In brief, 1405 subjects ≥50 years of age who resided in the selected district for >6 months were recruited and completed the eye examinations in 2003. With the exception of those who died, moved away from the study area, or were unable to be reached, all participants in the
Results
Among the 1405 participants who participated in the baseline examination, 791 (86.2%) of the 918 eligible survivors attended the 10-year follow-up visit. Of the 294 participants (27.1% of survivors) who did not attend the 10-year follow-up examination, 167 (56.8%) had moved from the study area and 127 (43.2%) declined participation. The basic characteristics of participants and nonparticipants have been reported elsewhere.23 In brief, the 791 participants were younger, more likely to be male,
Discussion
The incident rate of cataract surgery is constantly changing with the rapid development of the economy and population aging. Therefore, updated data on the incidence of cataract surgery may play an important role in effective policy formulation and resource allocation through an improved knowledge of the distribution and demand for cataract surgery and factors associated with uptake. This study describes the 10-year incidence and factors associated with cataract surgery in an older adult
