Abstract
Objectives: To investigate incident cataract surgery and to investigate determinants of cataract surgery uptake in Chinese adults.
Design: This nationally representative longitudinal study recorded self-reported incident cataract surgery, and measured biological, clinical and socioeconomical characteristics at baseline and endline.
Setting: In the first stage, 150 county-level units were randomly chosen with a probability-proportional-to-size sampling technique from a sampling frame containing all county-level units. The sample was stratified by region and within region by urban district or rural county and per capita gross domestic product. The final sample of 150 counties fell within 28 provinces of China.
Participants: Urban and rural Chinese persons aged 45 years and older.
Primary and secondary outcome measures: Incident cataract surgery (primary outcome) and the factors associated with incident cataract surgery (secondary outcome).
Results: Among 16 663 people enrolled in 2011, 13 705 (82.2%) attended follow-up in 2015. Among these, 167 (1.22%) reported incident cataract surgery. Those receiving surgery were significantly older (66.2±8.79 vs 58.3±9.18, p≤0.001) and more likely to report: illiteracy (44.9% vs 27.1%, p
Conclusions: In China, cataract surgical rates remain low; underserved groups such as rural dwellers are less likely to receive cataract surgery.
