Purpose:
China has among the lowest cataract surgical rates in Asia. This study was conducted to identify barriers to cataract surgery in rural China.
Methods:
All subjects having undergone cataract surgery and persons with presenting visual acuity
Results:
Interviews were completed on 71% to 86% of eligible subjects in both sites. Interviewed subjects did not differ significantly from nonrespondents with regard to age, sex, and presenting acuity in the better-seeing eye. A total of 214 (80.4%) nonsurgical and 131 (76.6%) surgical participants were interviewed, with a mean age of 71.8 +/- 8.0 and 73.7 +/- 7.4 years, respectively (P > 0.1).
